摘要：
A removable rivet (11) of the type comprising a shank (12) and a preformed head (13) at at least one end of the shank (12), the shank (12) being insertable through workpieces (19) and being capable of being permanently deformed to rivet the workpieces (19) together, includes the following features in combination:-
an annular groove (23) at the junction of the shank (12) and the head (13), the annular groove (23) extending radially inwardly of the diameter of the shank (12), thereby to facilitate separation of the head (13) from the shank (12) when a drill (22) of diameter substantially equal to that of the shank (12) is applied to the head (13) of an installed rivet (11) co-axially with the shank (12) until it meets the annular groove (23);
an annular rim (25) carried by the head (13) of the rivet (11) for co-operating with drilling apparatus (31, 32) comprising a drill (22), thereby to locate the drill (22) co-axially with the annular groove(23); and
abutment faces (28) carried by the head (13) of the rivet (11) for engaging dogs (34) a non-rotating sleeve (34) of the drilling apparatus thereby to prevent rotation of the rivet (11) under the influence of the rotating drill (22) (Figure 4).
