ABSTRACT:
A spanner socket wrench driveable by conventional socket wrench drivers and provided with a face having a pair of diametrically opposed pins held by means of set screws. A spring is disposed behind each pin so as to permit adjusting the amount of projection of the pin from the socket face by loosening the set screw, adjusting the free length of each pin to an appropriate value, and tightening the set screw. The spanner socket of the invention is particularly well adapted to install, adjust and remove rings, seals and like mechanical parts adapted for driving by spanner wrenches, and more particularly when they are disposed at the bottom of a recess or cavity.
