Abstract
An installation tool for use with locking fasteners which reduces cam off during use. The tool comprises a cylindrical socket wrench having a central axial bore which defines a recess on one end for attachment to a socket driver and an elliptical cavity on the opposite end for engaging the collar of the locking fastener. The installation tool further comprises one or more pockets positioned on the wrenching portion of the cavity. The pockets provide space in which collar mass is deformed. As the collar is deformed to lock the collar and bolt together, collar mass is deformed into the pockets on the tool. The deformed collar mass retains the tool and collar in an engaged position until the collar is completely deformed and the fastener is locked.
