IMPROVED BLIND FASTENER AND METHOD OF SETTING

摘要

There is disclosed herein a method of connecting together at least two workpieces (30, 32) using a blind rivet (10), which comprises the steps of biasing a blind side end face of a blind rivet (10) against a workpiece (30) and subsequently effecting rotation (41) of the blind rivet (10) whilst in abutment with the workpiece (30) to create a heat weakened region of the workpiece through which the blind rivet (10) can subsequently be inserted by a biasing force less than a biasing force normally required to effect piercing of the workpiece (30, 32) by such a blind rivet (10).
