Coiled Spring Pins

Standard Duty Coiled Spring Pins

The Coiled Spring Pin was invented by SPIROL in 1948. SPIROL offers Coiled Pins in three duties, light, standard and heavy, to provide a variety of combinations of strength, flexibility and diameters to accommodate different host materials and applications. Standard duty (sometimes called "medium" duty) Coiled Spring Pins are generally recommended for use in nonferrous and mild steel assemblies and provide the optimum combination of strength and flexibility in these materials. Standard duty Coiled Pins are also preferred in hardened components when there is enough space to accommodate the larger diameter to withstand the applied force because of their ability to absorb shock and vibration.
