Self-Retaining Tinnerman Speed Clip Fasteners solve a host of Knob-to-Shaft assembly problems. They eliminate inserts and setscrews for reduced molding costs and easier, faster, assembly. Stresses are distributed evenly around the hub during application while the strength and durability of spring steel reinforces critical wearing points and harnesses cold-flow tendencies. Knob-to-Shaft fasteners can be removed and replaced repeatedly without danger of loosening or developing "knob-wobble".
