Description:
The adjustment on this open end wrench is a stud at the intersection of two slots. The stud has teeth on the underside of its head. The teeth mesh with grooves on the surface of the adjacent wrench half. The stud is held in place by a spring, and can be pushed back sufficiently to slide, thereby changing the adjustment.
