ABSTRACT:
A socket wrench is shown having a socket driver head pinned to a clevis on a shaft. A sleeve is receivable over the shaft end and includes open ended slots pointing away from the clevis. The shaft includes a pin press fit within a cross bore on the shaft end, and the shaft and sleeve are axially slidable relative to each other; where in one position the pin engages one of the slots, and in another position, the shaft and sleeve spin freely of each other. A handle includes an internal bore which is profiled to compressively fit over the sleeve, and a chamber is defined between the sleeve and the end of the internal bore, to provide clearance for the axial movement of the shaft and sleeve.
