ABSTRACT:
A tool having several coaxially disposed socket members housed within each other and corresponding to conventional sizes. The sockets are spring loaded, and each reduces its diameter towards the outer end that prevents the abutting sockets contained therein from falling off as a result of gravity or the spring force of the different spring members associated with each one of the sockets. The springs members urge these sockets outwardly, and the springs members of the sockets that are smaller than the head of the bolt or screw being matched are overcome and retracted, thereby the matching socket cooperatively engages with the head. Corresponding covers provide the necessary support area for the springs to exert their force against their corresponding socket members. An upper master socket assembly is removably mounted to the larger socket member, and it provides suitable engagement for a crank or lever to produce the necessary torque to rotate the socket members.
