Abstract

This end-type wrench or spanner is used with a straight knurl nut. The wrench includes handle 1 and arcuate arms 2 and 3 formed at one end. The internal surface 4 of arms 2 and 3 is formed on approximately a 200 degree arc of constant radius. An inwardly projecting tooth 5 is formed on the distal end of arm 3 which can be longer than arm 2. The arcuate opening defined by internal surface 4 is dimensioned to fit around the periphery of a selected size nut while tooth 5 is dimensioned to be received within the knurled recesses of the nut. By engaging tooth 5 in a knurled recess and then moving handle 1 away from the tooth, the nut can be turned to either tighten or loosen it as desired.
