History
Allen created the Allen key in 1913 and created the Allen Manufacturing Company Inc advertisement for the Allen Safety Set Screw, a brand of
set screw, in the Automobile Trade Directory, January 1913.

W.G. Allen filed the first related patent in 1909 for its recessed hex-driven safety screws, a safety improvement over fasteners which protruded from machinery. While other hex keys were patented before and after this date, the name would persist. Allen left the company shortly after.
An advertisement for Allen safety screws would appear in the 1910 Annual Convention of International Association of Factory Inspectors.
In 1922, Allen Manufacturing Company produced sets of tools under the company name "Bay State", suggesting that they may have privately acquired another hardware manufacturer, namely the Bay State Pump Company.
Apex Tool Group owns the current trademark and has since renewed it.

No public announcement has been made for the end of productions under the Allen name.
