Method for attaching a headless crimping nut to a sandwich panel

摘要

The method involves fitting a headless rivet nut (10) onto a rivet nut setting tool (40) that is provided with a pierced anvil (42) and a mandrel (41). The mandrel is screwed into the rivet nut so as to press an end (16) of the rivet nut onto a surface (42B) of the anvil. The rivet nut is positioned in a blind hole. The surface of the anvil is pressed against the end of the rivet nut coming to press against a wall (31) of a panel. The rivet nut is set so as to squeeze the wall of the panel between the anvil and a flange (18) formed by deformation of the rivet nut.
