Abstract
A self-plugging blind rivet, of the kind comprising a tubular body having a head and a shank which is deformed by means of a headed stem which is disposed in the body and pulled so as to form a blind head and, if necessary, to cause the shank to bulb so as to grip workpieces of lesser thickness than the maximum for which the rivet is designed, is so shaped and dimensioned as to avoid the need for a crimping or hardening operation to be performed on the shank. Thus the shank is made of uniform hardness, and has a waist and a tail portion, the waist being of reduced external diameter compared with the tail portion, and the tail portion having a length B and an external diameter D which are related to satisfy the expression B=mD+n wherein B is the length in millimeters, of the tail portion; D is the external diameter, in millimeters, of the tail portion; n is a length, in millimeters, of from 2.15 to 2.73 millimeters, and m is a number from 0.373 to 0.527 inclusive.
