Custom Coiled Spring Pins for Shock Absorption, Vibration Resistance & Mechanical Retention

Coiled spring pins are formed from multiple layers of strip material rolled into a cylindrical section. Unlike a single-slit spring pin, the coiled structure allows the pin to flex radially and distribute applied loads through the wound material. This makes the pin suitable for shaft-to-hub connections, lever and linkage assemblies, hinge joints, and components exposed to repeated shock or vibration.

Standard and custom coiled spring pins can be manufactured in light duty, standard duty and heavy duty configurations, with the pin diameter, length, material, coil configuration and mechanical requirements defined according to the mating hole, host material and applied load. Metric and inch configurations can be produced to applicable standards including ISO 8750, ISO 8748, ISO 8751.
