Sockets and Drive Tools
Bonney was not one of the earliest producers of sockets and drive tools,
as they waited until around 1927 to introduce this group of tools.
By this time a number of other companies already had well-established lines
of socket tools,
including Blackhawk, Cornwell, Hinsdale, Milwaukee Tool & Forge, Mossberg, Snap-On,
and Walden,
plus many smaller companies.
The late entry did give Bonney one advantage though,
in that they offered a full line of alloy-steel sockets and drive tools from the beginning,
while other companies were in the process of switching from the earlier carbon-steel models.
1/2-Drive Socket Tools
The socket tools offered in 1927 were only for 1/2-drive,
but the 3/8- and 3/4-drive sizes followed later.
Although rarely seen,
Bonney also produced tools in 9/32-drive,
a drive size introduced by Snap-On in the mid 1920s.
The 9/32-drive tools were still listed in the 1938 catalog,
but by 1939 had been discontinued in favor of 1/4-drive.
4019 1/2-Drive 19/32 Socket
Fig. 184 shows
a 1/2-drive Bonney 4019 6-point socket of size 19/32,
marked "Chrome Vanadium" in a fancy script with the
CV-Circle logo in the center.
The finish is nickel plating.
The 40xx model number series was used for the first sockets offered by Bonney in 1927,
and the script "Chrome Vanadium" marking shown here is believed to be the earliest
marking style.
D14 1/2-Drive 7/16 Socket
Fig. 185 shows
a 1/2-drive Bonney D14 size 7/16 socket,
marked "Chrome Vanadium" in script with the
CV-Circle logo in the center.
The finish is nickel plating.
D40 1/2-Drive 1-1/4 Socket
Fig. 186 shows
a 1/2-drive Bonney D40 1-1/4 socket with an inset for the broaching detail.
The reduced base is marked "Made in U.S.A." with the
CV-Circle logo,
and the drive end has a drilled hole in one wall for more secure holding.
The socket construction appears to be cold-broached,
as some chatter marks are visible,
and the chips have been clipped against the walls below the broaching.
The socket base has a cross-hatched band with sufficient relief to assist with turning by hand,
a convenience feature often found on early sockets.
The socket walls are slightly tapered,
a feature of the Bonney Dxx socket series.
Bonney also offered a 1/2-drive Axx socket series with straight walls.
4081 1/2-Drive Offset (Ell) Handle
Fig. 187 shows
a Bonney 4081 1/2-drive offset handle,
marked with "Chrome Vanadium" and the
CV-Circle logo forged into the shank,
and with "Made in U.S.A." stamped on the head.
The overall length is 11.0 inches.
4095 1/2-Drive Universal
Fig. 188 shows
a Bonney 4095 universal,
marked "Chrome Vanadium" in a script font with the
CV-Circle logo in the center.
The overall length is 2.4 inches,
and the finish is chrome plating.
4096 1/2-Drive Flex-Head Handle
Fig. 189 shows
a 1/2-drive Bonney 4096 flex-head handle,
marked "Chrome-Vanadium" and "Made in U.S.A." with the
CV-Circle logo.
The overall length is 9.6 inches,
and the finish is chrome plate.
The knurled handle is equipped with a cross-bar hole with a detent ball,
as can be seen in the right inset.
The end is also broached for 1/2-drive,
allowing the tool to operate as an extension,
in addition to its other functions.
The drive head is not fitted with a detent ball,
but instead has some sort of friction mechanism to control its pivoting action.
4093 1/2-Drive Ratchets
Fig. 190 shows
a 1/2-drive Bonney 4093 female drive ratchet with its 4094 drive plug,
marked on the shank with "Bonney" and "Made in U.S.A." in forged raised letters.
The shank also has a forged-in code "GU....." visible at the right,
and shown in detail in the middle inset.
The overall length is 9.6 inches,
and the finish is cadmium plating.
Note that this ratchet is not marked with a CV or Bonaloy alloy specification.
The cadmium finish and lack of an alloy marking indicate production during the 1942-1945
wartime years.
Fig. 191 shows
a later 1/2-drive Bonney 4093 female drive ratchet,
marked "Bonney" and "Made in U.S.A." in forged raised letters,
with "Bonaloy" forged into the back side.
The shank also has a forged-in code "CX..." visible at the left.
The overall length is 9.6 inches,
and the finish is chrome plate.
Also shown is the standard Bonney 4094 drive plug (see lower left inset) with a "C.V." marking.
For this particular ratchet the "Bonaloy" marking and year code "X" indicate production in 1946.
The 4093 ratchet was among the original drive tools offered by Bonney,
and this ratchet model remained in production until being replaced by the A706 model around 1950.
4084 1/2-Drive Speeder/Brace
3/8-Drive Tools
Bonney introduced 3/8-drive tools some years after the initial 1/2-drive series,
and the new tools were given model numbers with a "T" prefix, as in "Tiny".
T2 3/8-Drive Offset (Ell) Handle
Fig. 193 shows
a 3/8-drive Bonney T2 fixed-head offset handle with a paneled shank.
The shank has forged-in markings "Made in U.S.A." on the top (see middle inset),
with "Chrome-Vanadium" and the
CV-Circle logo on the bottom.
The shank also has a forged-in code "EX" visible at the left,
near the drive head.
The overall length is 7.0 inches,
and the finish is chrome plating.
The year code "X" indicates production in 1932,
in the first cycle of the Bonney date code system.
T28 3/8-Drive Ratchets
The Bonney T28 ratchet was a 3/8-drive non-reversible model with an open gear,
introduced in the late 1920s or early 1930s.
The ratchet remained in production for a number of years,
and was still listed in the 1947 catalog.
We're fortunate to have several examples of this model as shown in the next figures.
Fig. 194 shows
an earlier 3/8-drive Bonney T28 ratchet with its T29A drive plug,
marked with "Bonney" and "Made in U.S.A." forged into the shank.
The back side has "Chrome-Vanadium" and the
CV-Circle logo forged into the shank,
with a forged-in code "KYv" visible at the right.
The overall length is 6.5 inches.
The original finish has been lost to wear and rust.
The year code "Y" indicates production in 1933.
The drive plug is marked "C.V." with the Bonney name and model.
Fig. 195 shows
a somewhat later Bonney CV T28 ratchet and drive plug,
marked with "Bonney" and "Made in U.S.A." forged into the shank.
The back side has "Chrome-Vanadium" and the
CV-Circle logo forged into the shank,
with a forged-in code "LR....." visible at the right.
The overall length is 6.5 inches.
The finish appears to be chrome plating,
but much has been lost due to wear.
The year code "R" indicates production in 1939,
in the second cycle of the Bonney date code system.
The drive plug is the Bonney model T29A.
Fig. 196 shows
a later example of a Bonney Bonaloy T28 ratchet,
marked with "Bonney" and "Made in U.S.A." forged into the shank,
with "Bonaloy" and a forged-in code "KX...." on the back side.
The overall length is 6.5 inches.
The "Bonaloy" marking and "X" year code indicate production in 1946.
T35 3/8-Drive Reversible Ratchets
In 1936 Bonney introduced the T35 reversible ratchet,
the first reversible model for the 3/8-drive line.
Fig. 197 shows
a 3/8-drive Bonney T35 reversible ratchet,
marked with the "Bonney" name forged into the shank,
with the model number and a forged-in "KV.." code on the back side.
The overall length is 6.5 inches,
and the finish is plain steel.
Note that this ratchet is not marked with a CV or Bonaloy alloy specification.
The plain finish and lack of an alloy marking indicate production during the 1942-1945
wartime years.
Bonney assembled their reversible ratchets with rivets instead of screws,
which made the tools more difficult to disassemble for cleaning or repair.
(The soft steel rivets are fairly easy to remove though.)
This particular example is badly worn from extensive use.
Fig. 198 shows
a later 3/8-drive Bonney T35 reversible ratchet,
marked with "Bonney" and "U.S.A." forged into the shank,
with the model number forged into the back side.
The shank also has a forged-in code "HY." visible at the left.
The overall length is 6.5 inches,
and the finish is chrome plating.
The "Y" year code and "U.S.A." marking indicate production in 1947.
PWA1397 3/8-Drive Flex-Head Handle
This next figure shows an example of Bonney production for Pratt-Whitney Aircraft.
Fig. 199 shows
a 3/8-drive Bonney PWA1397 flex-head handle,
stamped with the Bonney name and a model number for Pratt-Whitney Aircraft.
The overall length is 7.6 inches,
and the finish is black oxide.
The knurled handle is equipped with a cross-bar hole with a detent ball,
allowing use as a Tee-handle.
T30 3/8-Drive Flex-Head Handle
Fig. 200 shows
a 3/8-drive Bonney T30 flex-head handle,
stamped "U.S.A." with the Bonney name.
The overall length is 7.6 inches,
and the finish is chrome plating.
The knurled handle is equipped with a cross-bar hole with a detent ball,
allowing use as a Tee-handle.
V17 1/4-Drive Sliding Tee Handle
Fig. 201 shows
a Bonney V17 1/4-drive sliding Tee breaker bar,

V25 1/4-Drive Ratchet
Fig. 202 shows
a Bonney V25 1/4-drive reversible ratchet,
marked "U.S.A." with the company name.
The overall length is 4.4 inches.
The ratchet mechanism uses a 20-tooth drive gear with a pivoting pawl.
3/4-Drive Tools
By 1929 Bonney was offering a "Heavy Duty" line of sockets and drive tools in 3/4-drive.
An advertisement from that year shows a "No. H Heavy Duty Socket Wrench Set" consisting of
a "Hercules" forged ratchet, sliding Tee handle, two extensions, and ten hexagon sockets.
CV 4295 3/4-Drive Universal
Fig. 203 shows
