Do you mean Allen keys? Named after the company.

The Allen wrench trademark of the Allen Manufacturing Company of Hartford, Connecticut was taken out in 1943, and Allen became such a successful brand of hex key that many consumers in subsequent decades have assumed (reasonably but incorrectly) that the internal-wrenching hexagon drive was invented by someone named Allen.
