Alloy Artifacts  

The Armaloy Era

Armstrong's earlier alloy tools had been marked as "Chrome-Vanadium", "Alloy Steel", or some equivalent, but in August of 1946 the company began using "Armaloy" as the standard marking for alloy steel tools. ("Armaloy" was registered as a trademark in 1957.)

Since it probably took some time to change over the markings, a beginning year of 1947 is reasonable for "Armaloy" marked tools. Within this era there were relatively few changes in design to allow for estimation of manufacturing dates, but in 1978 the model number system was revamped to use 5-digit numbers. Unless other factors are known, we will use a range of 1947-1978 for Armaloy tools in the older numbering system.

For tools with a flat face, such as open-end or combination wrenches, the change from the Standard Armstrong Face Marking to the Armstrong Shank Marking has recently (2022) been estimated to have occurred around 1970. See the section on Manufacturing Dates for details.

Hopefully further review of the catalogs (and available examples) will help refine our date estimation guidelines.

Tappet Wrenches

For the Armaloy era Armstrong offered tappet wrenches in a 109x series, using the same design with unequal openings and 15 degree offset angles as the older 42x series.

The older 40x series wrenches with asymmetric offsets remained in production up until 1970, but appear to be quite rare.

The overall length is 8.4 inches, and the finish is chrome plating, with losses due to wear and rust.

The Standard Armstrong Face Marking indicates production up to around 1970.


1090-D Armaloy (Blackhawk-Armstrong) 1/2x9/16 Tappet Wrench

Some earlier examples of Armaloy tappet wrenches can be seen in tools marked for the Blackhawk-Armstrong line. These tools all bear the standard Armstrong markings of the time, clearly illustrating that these were really just standard Armstrong production with the Blackhawk name added. Blackhawk Manufacturing was acquired by New Britain Machine in 1955 and the tool production changed after that, providing a 1947-1955 date range for the Armaloy-marked tools.

[Armstrong (Blackhawk-Armstrong) 1090-D 1/2x9/16 Tappet Wrench]
Fig. 143. Armstrong (Blackhawk-Armstrong) 1090-D 1/2x9/16 Tappet Wrench, with Insets for Back Side and Marking Detail, ca. 1947-1955.

The overall length is 8.9 inches, and the finish is chrome plating.

This wrench is marked with Armstrong's "Armaloy" trademark, indicating production in 1947 or later.


Box-End Wrenches

Armaloy box wrenches were available in several different configurations, all denoted by industry-standard numbers with a 4-digit prefix to specify the design. Specifically, the 6xxx series denoted short angled wrenches, the 7xxx series denoted long angled wrenches, the 8xxx series denoted long offset wrenches, and the 9xxx series denoted short offset wrenches.

By the time of the Armaloy era, an earlier 5xxx series used for extra-heavy-duty offset box wrenches had been moved to the 8xxx series.


8723 Armaloy 3/8x7/16 Offset Box-End Wrench

[Armstrong Armaloy 8723 3/8x7/16 Offset Box-End Wrench]

8727 Armaloy 9/16x5/8 Offset Box-End Wrenches

The next two figures show examples of the 8727 offset box wrench.

[Armstrong Armaloy 8727 9/16x5/8 Offset Box-End Wrench]
Fig. 147. Armstrong Armaloy 8727 9/16x5/8 Offset Box-End Wrench, with Insets for Edge View and Back Side Detail, ca. Mid 1940s?

Fig. 147 shows an earlier Armstrong 8727 9/16x5/8 offset box wrench, stamped "Made in U.S.A." with the Strong-Arm logo on the shank, and with "Armaloy" on the back side.

The overall length is 9.7 inches, and the finish is plain steel.

The rough, unplated finish of this wrench suggests that it was probably made during the wartime period, but the "Armaloy" marking would normally indicate a manufacturing date after 1946. To reconcile these observations, this wrench may a very early example of the use of "Armaloy", perhaps an informal marking before the trademark was actually registered.

[Armstrong Armaloy 8727 9/16x5/8 Offset Box-End Wrench]
Fig. 148. Armstrong Armaloy 8727 9/16x5/8 Offset Box-End Wrench, with Inset for Back Side Detail, ca. 1947-1978.

Combination Wrenches

Armstrong offered Armaloy combination wrenches in an 11xx model series, the same numbering used by J.H. Williams. The 1948 catalog offered 18 sizes from 7/16 up to 1-7/16.

By 1956 combination wrenches were available in smaller sizes from model 1157 (7/32) to 1160 (3/8). Sizes 5/16 and under were made with hexagonal broachings.

By 1961 (catalog 700) Armstrong was offering extra-long combination wrenches in an 11xxL series, with 24 sizes from model 1160L (3/8) up to 1190L (2 inches).

After the introduction of the extra-long combination wrenches, the standard length wrenches remained available in 16 sizes from model 1157 (7/32) to 1167 (7/8).

Later Production

In 1978 Armstrong changed its model numbers to a 5-digit system, and this provides a convenient marker for the company's later production.

Armstrong's production after the 1994 acquisition by Danaher is believed to have omitted the "Armaloy" marking.

After Danaher's 1997 GearWrench acquisition, ratcheting box ends based on the GearWrench design began appearing in Armstrong tools.

27-513 9/16 Ratcheting Box-End Wrench

This next figure shows a wrench in a less common design, with one flat ratcheting box end and an angled box end of the same size. To be honest, we're not sure of the use cases that would call for this design, although it could be complementary to the first-generation GearWrench flat combination wrenches.
