ABSTRACT:
An improved temporary support pin which may be pushed into place rather than screwed into place and used with either English or metric threads. Resilient arms protruding from the support pin are depressed when a workpiece is pushed over them, and spring back into place to support the workpiece and allow a mechanic to have both hands free for replacing screws which attach the workpiece to its permanent mounting. The embodiment further includes a non-circular cross-section at the end gripped by the mechanic, to permit easy gripping, insertion, turning, and removal of the pin. The improved pin is preferably manufactured in one-step molding, significantly reducing the cost of its manufacture.
