FASTENER WITH A BELLEVILLE HEAD

摘要

The present invention relates to headed push-in fasteners of the type produced by Penn Engineering & Manufacturing Corp. known as TackPins and TackScrews. More specifically it relates to a Tack Pin or a Tack Screw with a Belleville head that provides the functionality of a Belleville washer without needing a separate part. When installed, the compression of the Belleville shaped head will cause a permanent loading to be applied under the head of the fastener, essentially creating a clamping force to the members being attached.
