Coiled Spring Pins

Light Duty Coiled Spring Pins

SPIROL invented the Coiled Spring Pin in 1948. Truly an engineered fasteners, the Coiled Pin is available in three duties, light, standard and heavy, to enable the designer to choose from the optimum combination of strength, flexibility and diameter to suit different host materials and application requirements. Their shock absorbing design dampens forces and vibration to prevent hole damage and prolong assembly life.

Light Duty Coiled Spring Pins are generally recommended for soft, brittle or thin materials such as plastics, aluminium, 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.
