ABSTRACT:
An improved tool for use in association with a deformable nut of a fastener includes a socket having inner surface that forms a cavity on the socket. The inner surface includes one or more engagement surfaces that are tapered inwardly at an angle that approaches a taper of a deformable wall of the deformable nut. In one embodiment the tapering of the engagement surfaces is provided by configuring the engagement surfaces to extend in a tapered fashion generally toward a central axis of the socket. In another embodiment, the tapering is provided by configuring the engagement surfaces to each extend in a spiral fashion about a spiral axis that may, for example, be parallel and spaced-apart from the central axis of the socket.
