ABSTRACT:
A wrench adapter is disclosed which can be inserted into and removed from standard size wrenches. The adapter includes a plurality of pins interconnected by a resilient retainer which operates to position the pins in an array arranged to fit into the corners of a mating wrench opening. The adapter permits the conversion of wrenches between inch and metric sizes, and also allows a wrench to be used with a damaged fastener or with cylindrical elements such as studs.
