A socket drive and socket having a stable univeral coupling, which is characterized by a drive shaft having a drive member at one end for interfacing with a ratchet wrench and the other end provided with a universal coupling configured to receive a socket, which is capable of adjustment both in alignment with the drive shaft and in 360 degree, angular rotation with respect to the drive shaft. Multiple, stable angular orientation of the socket in a 360 degree path of travel is facilitated by operation of a spring-loaded collar which is seated on the drive shaft by means of a snap ring and sleeve combination, and is biased against the socket.
