Light Duty Coiled Spring Pins are generally recommended for soft, brittle or thin materials such as plastics, aluminum, die castings, ceramics, and where holes are located close to an edge of the assembly. In situations not subjected to significant loads, such as when used purely for alignment or as an axle, light duty Coiled Pins are often used because of easy installation resulting from lower insertion force. Ask SPIROL for complimentary assistance with the design of your assembly to use SPIROL light duty Coiled Spring Pins. » Learn more!
