Abstract
An improved assembly for mounting a part onto a base member is provided by incorporating a tubular insert having a hollow inner core in a mounting hole in the part. A fastener, such as a bolt, machine screw or rivet, may then be inserted through the insert in the mounting hole for attachment to the base member. The tubular insert has an integral flange on the end which engages the fastener. The flange functions as the "washer" in conventional fastener assemblies. When the assembly is subjected to axial compression by the fastener, the insert collapses uniformly in an axial direction to absorb a substantial amount of the total compressive load exerted upon tightening the fastener.
