ABSTRACT:
A spin welded fastening assembly is constructed of two interfitting components. A circular base member formed of thermoplastic material has a circular disc portion with a workpiece engaging surface for friction welding and has a circular upstanding coupler portion integrally formed on the opposite surface of the disc portion for mounting a standoff member. The standoff member has a downwardly extending circular flange portion which snaps over the upstanding circular coupler portion of the circular base member. The circular flange portion of the standoff member has a closed end in the form of a transversely extending mounting plate portion having a central mounting aperture formed therethrough. The head of a quarter turn type fastener is installed in the mounting aperture of the standoff member. The snap fitting connection between the circular flange portion of the standoff member and the upstanding circular coupler portion includes a ratchet means for permitting the standoff member to be turned in one direction only. This rotating direction is opposite to the direction which the quarter turn fastener must be turned to be is installed into the mounting aperture of the standoff member.
