Early Plomb Wrenches
Troy Dietz found a very early wrench and asked us to post a page describing them.
These wrenches date from the early 1920's. They are named "Cap Screw" wrenches in an early undated and unnumbered catalog. By catalog #8, from 1928, they are listed as "Garage Wrenches".
The early wrenches were made from Ford Model T axles, which were plentiful and inexpensive. In the early 1900's, Model T axles were a great source of alloy steel strong enough to be forged into tools.
