ABSTRACT:
A removable rivet which includes a shank and a preformed head located at at least one end of the shank, the shank being insertable through workpieces and being capable of being permanently deformed to rivet the workpieces together. The rivet includes an annular groove at the junction of the shank and the head, the annular groove extending radially inwardly of the diameter of the shank, thereby to facilitate separation of the head from the shank when a drill of diameter substantially equal to that of the shank is applied to the head of an installed rivet co-axially with the shank until the drill meets the annular groove; an annular rim carried by the head of the rivet for cooperating with a drill, thereby to locate the drill co-axially with the annular groove; and abutment faces carried by the head of the rivet for engaging dogs of a non-rotating sleeve of the drilling apparatus thereby to prevent rotation of the rivet under the influence of the rotating drill.
