具有贝勒维尔头之紧固件;FASTENER WITH A BELLEVILLE HEAD

摘要

本发明系有关一种宾州工程&制造公司所生产，周知为平头销及平头螺丝类型之有头的推入式紧固件。更具体地说，它是有关一种具有贝勒维尔头之平头销及平头螺丝，其提供贝勒维尔垫圈的功能性，而无需个别零件。当安装时，贝勒维尔形头部的压缩将导致永久荷载被施加至紧固件的头部下，这本质上会对待附接之构件产生夹紧力。; 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 Bellville washer without needing a separate part. When installed, the compression of the Bellville 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.
