Tagline "We are the Original!"

Allen is a brand of hand tools, most widely known for its eponymous hex key wrenches. It is owned by Apex Tool Group.[1][2]


Originally named Allen Manufacturing Company,[3] the business produced hexagonal set screws and wrenches to fasten them. The terms "Allen wrench" and "Allen key" are derived from the Allen brand name and refer to the generic product category "hex keys."

W.G. Allen filed the first related patent in 1909 for hex-driven safety screws.[4] Prior to this recess driven fastener style, the driving end of fasteners tended to protrude out from machinery and create a safety hazard.

Apex Tool Group currently manufactures Allen-branded products in Dallas, Texas and Shanghai, China. They are made in L-key, folding, and T-handle styles.
