How to Select the Proper Diameter and Duty of a Coiled Spring Pin

Truly an “engineered-fastener,” the Coiled Pin is available in three “duties” to enable the designer to choose the optimum combination of strength, flexibility and diameter to suit different host materials and application requirements. The Coiled Pin distributes static and dynamic loads equally throughout its cross section without a specific point of stress concentration. Further, its flexibility and shear strength are unaffected by the direction of the
applied load, and therefore, the pin does not require orientation in the hole during assembly to maximize performance.
