Abstract
There is disclosed a driving tool for securing a fastener collar to a threaded pin in which the collar has a plurality of external, axial lobes at equally spaced angular increments. The driving tool has a driver socket with a collar receptacle which is open on at least one end and which fixedly receives a retainer sleeve which supports a plurality of driver balls that are fixedly and non-rotationally carried at spaced apart angular increments. The retainer sleeve is bored to form spherical recesses, each of which receives a driver ball. The inwardly directed faces of the balls protrude into the interior of the collar to form spherical lugs, and the opposite surfaces of the driver balls are ground or flatted to conform to the surrounding wall of the shell of the driving tool.
