Abstract

The rotary wrenching tool or spanner (20) has an opening to receive the head (24) of a threaded member. The opening has on the inner surface a number of arcuate concave curves (26), each such surface being defined as locus of points falling a given radial distance (R) from the axis. The opening also has a number of convex curves, each surface being defined as the concave curves. The wrench can be open ended (22) similar to an ordinary spanner or closed (20) similar to a ring spanner.
