Abstract
A socket wrench universal joint includes a socket engaging element movably mounted in the drive stud of the universal joint to engage a socket. An actuator is mounted to the universal joint for manipulation by a user, and a linking element links the actuator and the socket engaging element. The actuator allows the user to alter the socket retaining forces. In a quick release version the operator can release a socket from the drive stud of the universal joint by appropriately manipulating the actuator. In another version the user can enhance socket retaining forces by properly manipulating the actuator.
