Abstract
A molded elastomeric sleeve is carried by the rearward portion of a wrench socket. The sleeve has size indicia molded directly thereon (and may also be color coded) thereby facilitating a quick and convenient identification and selection of the respective socket from a tool box or kit. Suitable knurls on the outer diameter of the sleeve facilitate a manual rotation of the socket for seating a nut or bolt, prior to torquing with a conventional ratchet wrench. The knurls also prevent the socket from rolling, if placed sideways on a flat surface. Preferably, the rearward portion of the socket has a reduced diameter, thereby forming an annular shoulder between the forward and rearward portions of the socket, and the sleeve abuts against the annular shoulder. In an alternate embodiment, the sleeve is keyed to the socket, preferably by a "double dee" configuration, to prevent slippage or relative rotation between the socket and sleeve.
