摘要
A lockbolt has a collar (26), which may be pressed from sheet metal, swaged into transverse grooves (88) of the bolt progressively from the end of the collar remote from the workpiece along narrow circumferentially spaced segments. The setting tool accordingly has an anvil consituted by a ring of narrow jaws (50) with longitudinally extending ridges to engage the collar (26), shoulders of the jaws initially abutting the collar to clamp the workpiece between them and the head of the bolt. Operation of the tool then causes the jaws to rock about axis close to the periphery of the bolt. The shoulders of the jaws may indent the bolt to cause fracture substantially flush with the collar regardless of the workpiece thickness.
