ABSTRACT:
A universal socket tool for rotating a fastener element includes a rigid housing comprising a conventional socket casing having a polygonal shaped longitudinal chamber, the chamber having an end wall at its upper end and an open lower end. An array of primary engagement pins, each having upper and lower ends, are longitudinally oriented in the chamber. A pair of spaced apart, secondary engagement pins, each having upper and lower ends, are also longitudinally oriented in the chamber with the primary engagement pins disposed therebetween. The secondary engagement pins are preferably triangular in cross-section so as to fill the polygonal cavity of the housing. Springs are provided for attaching the primary and secondary engagement pins to the upper end of the chamber of the housing. In a second embodiment, a sleeve-type suspension mechanism is provided for positively securing the pins to the housing so that the pins cannot be pulled out of the housing. In a third embodiment, a sleeve-type suspension system incorporating a rack plate is further provided.
