Extending the Superrench Line

After the initial introduction of Superrench alloy-steel tools in 1925, Williams quickly expanded the line to include other wrench styles. By late 1930 Williams was offering a full line of sockets and drive tools, and box-end, waterpump, and S-shaped wrenches were available by 1931 (or earlier).

In this section we'll look at some of these later additions to the Superrench line.


Water-Pump Wrenches

In the late 1920s the Blue Point division of Snap-On introduced a new type of wrench that combined features of both open-end and box-end wrenches. The wrench opening had a 12-point broaching but was partially open, allowing it to slip over a shaft and turn a nut with more points of contact than an open-end wrench. The new wrench was intended for servicing the fragile packing nut on automobile water pumps, leading to its common name, the water-pump wrench.

The wrench design was based on a patent by B.B. Gillett, issued first as patent #1,626,809 in 1927, but reissued in 1929 as patent #RE17,417, the latter with an assignment to Blue Point Tools. An example of the Blue Point production can be seen as the Blue Point 940 Water-Pump Wrench.

J.H. Williams licensed the Gillett patent and produced water-pump wrenches similar to those offered by Blue Point, and also offered a double-ended version unique to Williams. Our earliest catalog reference for the Williams water-pump wrenches is from an A-341 Catalog Update dated July of 1931, which offered 15 models of single-ended wrenches and five models of the double-ended style. The Williams water-pump wrenches were produced at least through 1945, but were no longer listed in the A-50 catalog of 1947.

8960 3/4x1-1/32 Double-Ended Water-Pump Wrench

In addition to the single-ended water-pump wrenches, Williams also offered the water-pump design in a double-ended style believed to be unique to Williams. The 1931 Williams A-341 catalog offered five models of double-ended water-pump wrenches, which together covered the sizes needed to service the more popular automobiles. The models and sizes were 8960 (3/4x1-1/32), 8960B (7/8x1-1/8), 8962 (1x1-3/16), 8962D (1-1/16x1-1/4), and 8966 (1-5/16x1-1/2). These five wrenches were also available together as a "Water-Pump Set" No. 8960 with a $20.25 list price. (Note that the set oddly has the same number as one of the component wrenches.)

The next figures show examples of this unusual double-ended style.

[Williams 8960 3/4x1-1/32 Double-Ended Water-Pump Wrench]
Fig. 190. Williams 8960 3/4x1-1/32 Double-Ended Water-Pump Wrench, with Inset for Reverse Detail, ca. 1931 to Early 1940s.

Fig. 190 shows a Williams 8960 3/4x1-1/32 water-pump wrench, stamped "Williams" and "Made U.S.A." with the W-Diamond logo, and with a "Patent RE.17417" patent notice. The shank is marked with "Water Pump Superrench" forged into the front, with "Chrome-Molybdenum" forged into the reverse.

The overall length is 8.0 inches, and the finish is chrome plating with polished faces.


S-Shaped Wrenches

The S-shaped style of open-end wrench was not among the earliest models in the Superrench line, but was introduced some time after 1933. The 1937 A-409 catalog update offered S-shaped wrenches under the heading "General Service Wrenches", apparently to distinguish them from their light-duty carbon-steel counterparts. A total of 29 models were available, ranging in size from the 3/8x7/16 model 1075B up to the 1-1/8x1-5/16 model 1085K.


1077-S 7/16x1/2 S-Shaped Open-End Wrench

[Williams 1077-S 7/16x1/2 S-Shaped Open-End Wrench]
Fig. 194. Williams 1077-S 7/16x1/2 S-Shaped Open-End Wrench, with Inset for Reverse Detail, ca. Mid 1930s.

Fig. 194 shows a Williams 1077-S 7/16x1/2 S-shaped open-end wrench, marked "Forged in U.S.A." with the W-Diamond logo on one face. The markings on the shank are stamped instead of forged, with the "Superrench" trademark on the front and "Chrome-Molybdenum" on the reverse.

The overall length is 7.2 inches, and the finish is chrome plating with polished faces, though some finish has been lost to wear and rust.


1085 1x1-1/8 S-Shaped Open-End Wrench

[Williams 1085 1x1-1/8 S-Shaped open-end Wrench]
Fig. 195. Williams 1085 1x1-1/8 S-Shaped Open-End Wrench, with Inset for Reverse Detail, ca. Mid 1930s.

Fig. 195 shows a similar Williams 1085 1x1-1/8 S-Shaped open-end wrench, marked "Forged in U.S.A." with the W-Diamond logo on one face. The markings on the shank are stamped instead of forged, with the "Superrench" trademark on the front and "Chrome-Molybdenum" on the reverse.

The overall length is 12.1 inches, and the finish is chrome plating with polished faces.


Round-Shank Box-End Wrenches

Williams introduced 12-point box-end wrenches some years after the first "Superrench" wrenches were offered. Although the exact date is not known, box-end wrenches were definitely available by 1931, based on an A-373 catalog update from that time. These first generation box wrenches featured round shanks and were marked "Duohex-Box", with "Duohex" signifying the double-hex (12-point) broaching.

The early 12-point wrenches were also marked with a notation for patent #1,424,069, issued in 1922 to F. Blackmar. This patent describes the design of a 12-point box wrench with an offset handle, and appears to have a bit of a curious history. There's no patent assignment listed with the initial patent document, but Snap-On seems to have acquired it at a later date, possibly around 1930. In the early 1930s Snap-On marked some 12-point wrenches with the patent number, and a few other companies did so as well. (Snap-On also marked some 12-point sockets with the patent.)

The Williams catalogs for 1931 and 1933 acknowledge licensing the Blackmar patent, but by 1937 were no longer mentioning it in the catalogs. Thus the presence of the patent marking on a wrench indicates a likely production date in the early 1930s.

Box wrenches were initially offered in three styles or patterns: a single-offset style with both openings of the same size, plus standard and short double-offset styles with different-sized openings. In later years two new styles were added, standard and short box wrenches with straight (non-offset) shanks and angled box ends. These new angled box wrenches were also associated with the introduction of an Oval-Shank Design.

The opening sizes for the double-offset (and angled box-end) wrenches were chosen to follow the same pairings as the older industry-standard open-end wrench models. (See our table Industry-Standard Wrench Models for more information.) The model numbers for the wrenches were then assigned by adding a prefix number to the industry-standard number for the same size combination. Since box wrenches were offered in several configurations -- angled box-ends, offset shanks, and standard or short lengths -- different prefixes were needed to distinguish the models.

For the earliest models Williams used an 8000 prefix for the standard double-offset box wrenches and a 9000 prefix for the short offset models. For example, a 1/2x9/16 wrench in the standard double-offset box style became an (8000 + 725B) or Model 8725B Wrench.

Later models used a 6000 prefix for the short angled box wrenches and a 7000 prefix for the standard angled box wrenches. (A 4000 prefix was also used briefly, possibly only for military contracts during the war.) As another example, a 3/8x7/16 wrench in the short angled box style became a (6000 + 723) or Model 6723 Wrench.

What about the model numbers for the single-offset wrenches? Since these wrenches had two equal openings, they didn't fit the pattern of the industry-standard models, and so were given a separate series of 81xx model numbers.

We're now ready to look at some examples of the box wrenches, and we'll begin with a fine example of an early double-offset "Duohex" box wrench.


8725B "Duohex-Box" 1/2x9/16 Offset Box Wrench

[Williams 8725B Duohex-Box 1/2x9/16 Offset Box Wrench]
Fig. 196. Williams 8725B "Duohex-Box" 1/2x9/16 Offset Box Wrench, with Insets for Side and Reverse Detail, ca. 1931-1935.

Fig. 196 shows a Williams 8725B 1/2x9/16 offset box wrench, marked "Superrench" with the W-Diamond logo. Additional markings on the shank are "Duohex-Box" and "Made in U.S.A." with "Pat. No. 1424069".

The overall length is 9.3 inches, and the finish is chrome plating with polished ends.

The patent notice refers to patent #1,424,069, issued to F. Blackmar in 1922.


8729 "Duohex-Box" 5/8x3/4 Offset Box Wrench

[Williams 8729 Duohex-Box 5/8x3/4 Offset Box Wrench]
Fig. 197. Williams 8729 "Duohex-Box" 5/8x3/4 Offset Box Wrench, with Insets for Side and Reverse Detail, ca. 1931-1935.

Our next example in Fig. 197 is a similar early wrench in a less commonly-seen size, a Williams 8729 5/8x3/4 offset box wrench. The shank is marked "Superrench" with the W-Diamond logo, plus "Duohex-Box" and "Made in U.S.A." with "Pat. No. 1424069".

The overall length is 11.4 inches, and the finish is chrome plating with polished ends.

The patent notice refers to patent #1,424,069, issued to F. Blackmar in 1922.

The side view in the upper inset shows the proportions of the hefty round shank, and the offset bend is convex on both sides where it joins the box.


8729A "Duohex-Box" 3/4x25/32 Offset Box Wrench

This next example of the "Duohex-Box" series is a bit of a mystery.

[Williams 8729A Duohex-Box 3/4x25/32 Offset Box Wrench]
Fig. 198. Williams 8729A "Duohex-Box" 3/4x25/32 Offset Box Wrench, with Insets for Side and Reverse Detail.

Fig. 198 shows a Williams 8729A 3/4x25/32 offset box wrench, marked "Superrench" with the W-Diamond logo and "Duohex-Box", but without a patent notice.

The overall length is 11.4 inches.

This example is a bit puzzling in that the 8729A model is not listed in the Williams catalogs from 1931 through the early 1940s, when the round-shank style was in production. The 8729A size is shown in the 1945 A-409 catalog, but by that time the box wrench production would have been in the oval-shank style. It's possible that this wrench was a special-order item.


8731A "Duohex-Box" 3/4x7/8 Offset Box Wrench

[Williams 8731A Duohex-Box 3/4x7/8 Offset Box Wrench]
Fig. 199. Williams 8731A "Duohex-Box" 3/4x7/8 Offset Box Wrench, with Insets for Side and Reverse Detail, ca. 1931-1935.

Fig. 199 shows a Williams 8731A 3/4x7/8 offset box wrench, marked "Superrench" with the W-Diamond logo, plus "Duohex-Box" and "Made in U.S.A." with "Pat. No. 1424069".

The overall length is 12.9 inches.

The patent notice refers to patent #1,424,069, issued to F. Blackmar in 1922.


8032A "Duohex-Box" 13/16x31/32 Offset Box Wrench

[Williams 8032A Duohex-Box 13/16x31/32 Offset Box Wrench]
Fig. 200. Williams 8032A "Duohex-Box" 13/16x31/32 Offset Box Wrench, with Insets for Side and Reverse Detail, ca. 1931-1935.

Fig. 200 shows a Williams 8032A 13/16x31/32 offset box wrench, stamped with "Superrench" and the W-Diamond logo on the shank, with "Duohex-Box" and "Made in U.S.A." plus "Pat. No. 1424069" on the reverse.

The overall length is 12.9 inches, and the finish is chrome plating.

The patent notice refers to patent #1,424,069, issued to F. Blackmar in 1922.


8037 "Duohex-Box" 1-1/16x1-1/4 Offset Box Wrench

Our next figure shows a much larger example of the early duohex-box wrenches.

[Williams 8037 Duohex-Box 1-1/16x1-1/4 Offset Box Wrench]
Fig. 201. Williams 8037 "Duohex-Box" 1-1/16x1-1/4 Offset Box Wrench, with Insets for Side and Reverse Detail, ca. 1931-1935.

Fig. 201 shows a Williams model 8037 1-1/16x1-1/4 offset wrench, marked "Superrench" with the W-Diamond logo, plus "Duohex-Box" and "Made in U.S.A." with "Pat. No. 1424069".

The overall length is 17.0 inches, and the finish is chrome plating with polished ends.

The patent notice refers to patent #1,424,069, issued to F. Blackmar in 1922.

In 1931 this model had a list price of $5.01 and was the second-largest box-end wrench offered by Williams, exceeded only by the model 8039. But by 1950 Williams was offering much larger sizes, up to the model 8053 2-9/16x2-3/4 behemoth.


9725B "Duohex-Box" 1/2x9/16 Short Offset Box Wrench

The next two figures show examples of the Williams 9000-series "Duohex-box" short offset box-end wrenches, one of the initial styles offered in 1931. The 9000 series wrenches were offered in four models: 9723 (3/8x7/16), 9725 (7/16x1/2), 9725B (1/2x9/16), and 9727 (9/16x5/8).

[Williams 9725B Duohex-Box 1/2x9/16 Short Offset Box Wrench]
Fig. 202A. Williams 9725B "Duohex-Box" 1/2x9/16 Short Offset Box Wrench, with Insets for Side and Reverse Detail, ca. 1931-1935.

Fig. 202A shows an early Williams 9725B 1/2x9/16 short offset box wrench, stamped with "Superrench" and "No. 9725B" plus the W-Diamond logo on the shank, with "Duohex-Box" and the fractional sizes on the reverse. The reverse is also stamped with "U.S.A." and a "Pat. No. 1424069" patent notice, visible on the upper side of the lower inset.

The overall length is 5.8 inches, and the finish is chrome plating, with extensive losses due to wear.

The patent notice refers to patent #1,424,069, issued in 1922 to F. Blackmar and later licensed by Snap-On. The Williams catalogs from the early 1930s note the use of this patent for their box wrenches, providing an estimated 1931-1935 manufacturing date.

A later example of this model can be seen as the Williams 9725B Oval-Shank Short Box Wrench.


9727 "Duohex-Box" 9/16x5/8 Short Offset Box Wrench

[Williams 9727 Duohex-Box 9/16x5/8 Short Offset Box Wrench]
Fig. 202B. Williams 9727 "Duohex-Box" 9/16x5/8 Short Offset Box Wrench, with Insets for Side and Reverse Detail, ca. 1935-1939.

Fig. 202B shows a Williams 9727 9/16x5/8 short offset box wrench, stamped "Superrench" with the W-Diamond logo on one side, with "Duohex-Box" and "Made in U.S.A." on the reverse.

The overall length is 6.3 inches. The original finish was chrome plating, but much has been lost due to rust.

This wrench is not marked with the Blackmar patent generally noted on early 1930s production, suggesting a later manufacturing date in the range 1935-1939.


Single-Offset Box Wrenches

In addition to the familiar double-offset box-end wrenches, Williams also produced a series of wrenches with one offset box and one straight, and with both openings of the same size. This wrench style was popular in the later 1920s and 1930s, and could be regarded as an early form of the combination wrench. Williams referred to these as single-offset wrenches, and we'll show several examples in the next figures.

Based on a review of the Williams catalogs, single-offset wrenches were listed from at least 1931 up through 1941, but had been discontinued by 1945. We have examples with cadmium or plain finishes that were likely made during the wartime years after 1942, so it's probably reasonable to assume production through 1944.

Single-offset wrenches were also available from a number of other manufacturers, including Armstrong, Blackhawk, Blue Point (Snap-On), Bonney, Mossberg, and Walden. Examples of these other wrenches include the Blackhawk 2924, Blue Point X-18, Bonney "CV" 2818, APCO-Mossberg 974, and Walden-Worcester 2114.


8128 "Duohex-Box" 7/16 Single-Offset Box Wrench

[Williams 8128 Duohex-Box 7/16 Single-Offset Box Wrench]
Fig. 203. Williams 8128 "Duohex-Box" 7/16 Single-Offset Box Wrench, with Insets for Side View and Reverse Detail, ca. 1942-1944.

Fig. 203 shows a Williams 8128 7/16 single-offset box wrench, stamped "Superrench" with the W-Diamond logo on the shank, with "Duohex-Box" and "Made in U.S.A." on the reverse.

The overall length is 8.6 inches, and the finish is cadmium plating.

The cadmium finish indicates likely wartime production, so the estimated manufacturing date is 1942-1944.


8132 "Duohex-Box" 1/2 Single-Offset Box Wrench

[Williams 8132 Duohex-Box 1/2 Single-Offset Box Wrench]
Fig. 204. Williams 8132 "Duohex-Box" 1/2 Single-Offset Box Wrench, with Insets for Side View and Reverse Detail, ca. 1930-1931.

Fig. 204 shows an early Williams 8132 1/2 single-offset box wrench, stamped "Superrench" with the W-Diamond logo on the shank, with "Duohex-Box" and the fractional sizes on the reverse (see lower inset).

The overall length is 9.3 inches, and the finish is chrome plating.

The lack of a patent notice or "Made in U.S.A." marking on this wrench indicates a very early production date, probably in 1930 or 1931.


8140 "Duohex-Box" 5/8 Single-Offset Box Wrenches

The next figures show three generations of the Williams 8140 single-offset wrench.

[Williams Early 8140 Duohex-Box 5/8 Single-Offset Box Wrench]
Fig. 205. Williams Early 8140 "Duohex-Box" 5/8 Single-Offset Box Wrench, with Insets for Side View and Marking Detail, ca. 1930-1931.

Fig. 205 shows an early Williams 8140 5/8 single-offset box wrench, stamped "Superrench" with the W-Diamond logo on the shank, with "Duohex-Box" and the fractional sizes on the reverse (see lower inset).

The overall length is 10.7 inches, and the finish is chrome plating with polished box ends.

The lack of a patent notice or "Made in U.S.A." marking on this wrench indicates a very early production date, probably in 1930 or 1931.


[Williams 8140 Duohex-Box 5/8 Single-Offset Box Wrench]
Fig. 206. Williams 8140 "Duohex-Box" 5/8 Single-Offset Box Wrench, with Insets for Side View and Marking Detail, ca. 1931-1935.

Fig. 206 shows a slightly later Williams 8140 5/8 single-offset box wrench, stamped "Superrench" with the W-Diamond logo. The reverse is stamped "Made in U.S.A." and "Pat No. 1424069", with "Duohex-Box" and the fractional sizes on the line below (see lower inset).

The lack of a patent notice or "Made in U.S.A." marking on this wrench indicates a very early production date, probably in 1930 or 1931.


Second Line "Chrome-Alloy" or "Cromal" Wrenches

Before moving on to the next section, it's worth mentioning a second line of Williams box wrenches offered as value or economy tools. These wrenches were made with round shanks and chrome-alloy steel and were generally very similar to the Duohex-box series. These wrenches were marked with either "Chrome-Alloy" or "Cromal" without the Williams name or logo, but are easily recognizable as Williams production by their design and construction.

Currently our only catalog reference for the "Chrome-Alloy" line is the H. Channon Company Catalog No. 102, undated but from around 1936. The catalog lists the wrenches in four sets: the No. 185 and 186 sets of long offset box wrenches, a No. 193 set of short offset box wrenches, and a No. 176 set of straight (angled) box wrenches.

The catalog listing doesn't provide the model numbers for individual wrenches, as they were available only in sets. However, based on the examples found, the model numbers were derived by adding a "1" prefix to the standard Williams model number. For example, the 18731A Chrome-Alloy Box Wrench corresponds to the standard 8731A Duohex-Box Wrench.

Early Angled Box Wrenches

By 1937 Williams had introduced a new style of angled box wrenches, a design with a straight shank but with the box ends set at an angle for clearance. The new wrench models were offered in a 6000 series of short wrenches and a 7000 series of standard length wrenches, and both series were listed as part of the "Duohex-Box" line. However, the angled box wrenches were produced with an oval shank, rather than the round shank being used for the other box wrenches.

Along with the new oval shank design came a new marking style as well, with the markings consisting of two lines of text arranged around the W-Diamond logo. Initially the text included "Duohex-Box" and "Superrench" on the first line with the model number and "Forged in U.S.A." below, but this was later changed to the modern form with "Williams" and "Superrench" followed by "Forged in U.S.A." and an alloy specification.

The oval-shank design worked well and within a few years Williams had redesigned most of their other box-end wrenches to use oval shanks. The transition from round to oval shanks with the modern form of markings is believed to have occurred around 1940. Two exceptions continued to use round shanks: the single-offset wrenches and certain very large double-offset wrenches. The single-offset style was soon to be discontinued and is not known to have been produced in an oval-shank version.

The angled box wrenches with the transitional marking form were only produced for a short time, from around 1937 to 1939, and the relatively precisely known manufacturing dates makes them useful for study. In this section we'll look at some examples of angled box wrenches with the early transitional markings.


7025 1/2x19/32 Duohex-Box Wrench with Early Transitional Markings

[Williams 7025 1/2x19/32 Box-End Wrench]

Our first example of the transitional form is shown in Fig. 213, a Williams 7025 1/2x19/32 box-end wrench with an oval shank. The shank is stamped "Duohex-Box" and "Superrench" on one line, with the model number and "Forged in U.S.A." clustered around the W-Diamond logo. The fractional sizes appear to the left and right of the other markings, set off by lines above and below the sizes, and the shank is also stamped "Chrome-Alloy" on the reverse.

The overall length is 8.5 inches, and the finish is chrome plating with polished ends.

The upper inset shows a side view of the wrench, illustrating the straight shank with angled box ends.

This wrench is not marked for its alloy content.


Oval-Shank Box-End Wrenches

By around 1939 or 1940 Williams was using the oval-shank style for most of its box wrenches, and for combination wrenches as well. The only exceptions among the box wrenches were the single-offset models, which were soon to be discontinued anyway, plus certain very large offset box wrenches that continued to be made with round shanks.

The marking style of the mature oval shank design consisted of two lines of text, with "Williams" and "Superrench" stamped on the top line, followed by "Forged in U.S.A." and an alloy specification on either side of W-Diamond logo. The reverse side was stamped with the model number in the center and the fractional sizes on either side.

Box wrenches were produced with oval shanks until approximately 1954, when Williams introduced a new style with raised panels. (See our later section for examples of the Williams Raised Panel Style.)

The overall length is 25.0 inches, and the finish is gray paint.


9723 3/8x7/16 Short Offset Box-End Wrenches, Oval-Shank Style

In addition to the 8000 series of standard-length offset box wrenches, Williams offered a 9000 series of short offset box wrenches.

[Williams 9723 3/8x7/16 Short Offset Box Wrench]
Fig. 238. Williams 9723 3/8x7/16 Short Offset Box Wrench, with Insets for Side View and Reverse Detail, 1945.

Our first 9000 series example is shown in Fig. 238 at the left, a Williams 9723 3/8x7/16 short offset box wrench marked "Williams Superrench" on the top line, with "Forged in U.S.A." and "Alloy Steel" on either side of the the W-Diamond logo. The reverse is marked with the model "No. 9723" flanked by the fractional sizes. The overall length is 4.8 inches.

The finish is plain steel with some traces of gray paint, an indication of a likely manufacturing date in 1942-1945. But for this example we can do better; a careful examination shows a small "G" code stamped in front of the "9723" model (see inset).

The "G" code was used to indicate a manufacturing date in 1945 under restrictive government regulations, and its use by Snap-On is well-known. The code is sometimes seen for other manufacturers; see for example the Duro-Chrome 1027 Wrench.

The use of the "Chrome-Alloy" marking and plain finish suggest production during the early war years 1942-1943.


Combination Wrenches

Williams was relatively late in offering combination wrenches, as this style did not appear in their catalogs until sometime after 1937. The now-familiar combination style, with an open and box end of the same size, had been developed in the early 1930s by Plomb Tool and almost simultaneously by Bonney. Combination wrenches became very popular and were quickly adopted by other major manufacturers.

The Williams A-409 catalog update of 1940 shows combination wrenches with an oval shank, similar to the oval design used for most box-end wrenches at the time. But unlike the box-end wrenches, the combination wrenches were made with raised letter markings for the Superrench trademark. Combination wrenches with the oval shank remained in production until about 1954, when the raised-panel style was introduced.


1159 5/16 Combination Wrench

[Williams 1159 5/16 Combination Wrench]
Fig. 245. Williams 1159 5/16 Combination Wrench, with Insets for Reverse and Side View, ca. 1947-1954.

The overall length is 4.3 inches. The finish is chrome plating with some loss due to wear, revealing the copper undercoating in some areas.

The W-Diamond logo with "U.S.A." face marking is a variant of the "Williams U.S.A." logo used for smaller wrench faces.


1161 7/16 Combination Wrench

[Williams 1161 7/16 Combination Wrench]
Fig. 246. Williams 1161 7/16 Combination Wrench, with Inset for Reverse Detail, ca. 1947-1954.

Fig. 246 shows a Williams 1161 7/16 combination wrench, stamped "U.S.A." with the W-Diamond logo on the face. The shank is marked with the "Superrench" trademark in forged raised letters, with "Alloy" and an "II" code forged into the reverse.

The overall length is 5.3 inches, and the finish is chrome plating with polished ends and faces.

The W-Diamond logo with "U.S.A." face marking is a variant of the "Williams U.S.A." logo used for smaller wrench faces.

A later version of this model can be seen as the Williams 1161 Panelled Combination Wrench.


Early 1162 1/2 Combination Wrench

[Williams Early 1162 1/2 Combination Wrench]
Fig. 247. Williams Early 1162 1/2 Combination Wrench, with Inset for Reverse and Side View, ca. 1937-1938.

The overall length is 6.7 inches, and the finish is plain steel.

The front face of this wrench would normally be stamped with the Williams scroll logo and W-Diamond trademark, but either the markings were omitted or have been worn down.

The "Chrome-Alloy" marking suggests production in the 1930s to early 1940s, and the plain finish suggests production during the early wartime years.

[Williams 1163 9/16 Combination Wrench]

The overall length is 10.5 inches.

Some readers may have wondered about the coppery color of this wrench, and in this case it's not an artifact of the lighting. The original chrome plating has worn off to leave a fairly uniform copper coating, possibly indicating a problem with the original plating process. Normally a chrome plated finish is applied as chrome over nickel over copper, but the nickel layer might have been omitted from this example.


1167 7/8 Combination Wrench

[Williams 1167 7/8 Combination Wrench]
Fig. 257. Williams 1167 7/8 Combination Wrench, with Inset for Reverse Detail, ca. 1945-1946.

Wartime Superrench Models

The Superrench tools shown in the previous sections have all been standard models listed in the Williams catalogs, with the exception of a few "Special" models made for particular customers. But in addition to these standard models, Williams also produced wrenches in at least two other Superrench lines, a 3000-series of open-end wrenches and a 4000-series of angled box wrenches. No catalog references are known for these alternate lines, although enough examples have been found to suggest that they were produced in substantial quantities.

The 3000-series of open-end wrenches are basically very similar to the corresponding standard 1000-series Superrench models, and likewise the 4000-series of box wrenches are very similar to the corresponding standard 7000-series Superrenches. In both cases the major exception is that the alternate 3000 and 4000 series models are known only with plain or cadmium finishes, rather than the standard chrome plated finish.

The use of the plain or cadmium finishes suggests that these alternate models were produced for special wartime contracts in the 1941-1945 time frame. The use of alternate model numbers may have been due to slightly different specifications, or perhaps the standard lifetime warranty was not extended to these tools.


3000-Series Open-End Wrenches

The 3000-series of open-end wrenches are nearly identical to the corresponding standard 1000-series Superrench models, but were produced only with cadmium or plain finishes.
