Abstract: The present invention provides a socket wrench for electrical locknuts that is highly tolerant of size differences of electrical locknuts of a nominal size and the number and spacing of lugs thereon. The socket wrench, in its most simple form, is machined from a single piece of metal, and includes a cylindrical wall that is unitary with a socket ceiling having a square drive aperture centered therein. A pair of diametrically-opposed semi-cylindrical vertical projections extend inwardly from the cylindrical wall. The vertical projections operate on a pair of diametrically-opposed lugs on the electrical locknut. The semi-cylindrical shape of the vertical projections causes the socket to self-center on an engaged locknut when the socket is turned in either clockwise or counterclockwise direction.

Abstract: A pipe extraction tool grips the inside of a pipe or other such conduit to facilitate removal of a pipe which can not otherwise be removed. The extraction tool uses expandable jaws to grip the inside of the pipe.
