Abstract: A fastener is disclosed which is installed quickly and easily the first time by simply driving a frangible drive pin. The drive pin has ribs which cooperate with grooves in an axially extending bore in the fastener body to limit distortion of the fastener due to rotational stresses imparted thereto by a tool engaging the head of the fastener. Subsequent to the initial installation of the fastener by the driving of the frangible drive pin the fastener is reusable in the same manner as a conventional threaded fastener.

Abstract: The present invention relates generally to a resilient clip for supporting elongated articles such as cylindrical and ribbon-like electrical conductors, and the like. The invention disclosed includes a base member which may be secured to a support by an adhesive and/or a retaining fastener. The base has an integrally formed flexible arm extending upwardly therefrom which superimposes the exposed side of the base. The free end of the arm has a hinged connection and a pressure plate integrally formed therewith, with the hinged connection interposed between the end of the arm and the pressure plate. The pressure plate position when the clip is relaxed, normally is adjacent to and substantially parallel to the base. The hinged connection at the free end of the arm is formed by a reduction in the thickness of the material adjacent to where the arm attaches to the pressure plate.
