ABSTRACT:
A socket tool has an internal hole that is adapted to receive a standard size thread corresponding to the size of the nut being driven. A set of such socket tools may be driven using one or more hollow extensions that engage a socket tool, the extension having a hollow portion adapted to receive the largest standard size thread of the set of socket tools. In some embodiments, an adapter tool may connect various driving tools to either a socket tool or an extension.
