Abstract
A stud (1) for mounting a pulley (2) to a plate (3) by a cold forming process has a large diameter head (5), a cylindrical shank (6) which acts as the stub shaft for the pulley (2), the end of the shank remote from the head being connected to a smaller diameter shank (7) via a shoulder (9) (which may include an annual grove (10) into which the plate (3) is deformed), and, beyond the smaller diameter shank, an e.g. threaded shaft (8). To resist rotation after the stud (1) is cold formed to the plate (3), the stud (1) has ribs or studs or flat facets on the shoulder or on the narrow shank (7) against which the plate is cold formed.
