ABSTRACT:
A generally U-shaped attachment of resilient sheet metal is adapted to be axially captured relative to the drive shank and wrench socket of a socket wrench assembly so as to extend along opposite sides of the socket and then inwardly of the fastener receiving opening in the wrench socket to releaseably retain the head of the fastener therein during application or removal of the fastener from a mating part. The inwardly extending portions of the attachment provide cam surfaces which facilitate reception, retention and removal of a fastener head from the wrench socket opening.
