Installation Initiated Bolt Capturing Compression Limiter

摘要

A one-piece compression limiter that is simple to manufacture and install with a bolt or having a head, a smooth shank portion, and an enlarged lead portion including threads. The limiter and bolt can be supplied separately. At the time of installation into the though hole of a component, the limiter is first advanced with clearance along the lead portion toward the head into a loose position around the shank. The bolt is then aligned within the hole and the head is pushed to urge the remainder of the bolt and limiter into the hole together such that the wall of the hole compresses the limiter radially inwardly into close proximity to the shank, thereby trapping the limiter between the head and lead portion of the bolt. The disclosed limiter is a cylindrical tube with a longitudinal slit and a plurality of inwardly projecting dimples.
