Roll/Spring
A roll spring pin, also known as a tension pin, is a hollow cylindrical fastener designed for aligning and joining components in mechanical assemblies. Constructed with a split down its length, the pin exerts outward radial force upon insertion into corresponding holes, ensuring a secure fit and alignment. Roll spring pins excel at transferring both tension and shear loads between connected parts, distributing forces evenly and resisting stress concentration. Their ease of installation and removal, coupled with vibration resistance, makes them a cost-effective choice for various applications, particularly in automotive, machinery, and manufacturing industries. The pin's spring-like action provides flexibility and reliability, contributing to its widespread use in scenarios where movement and vibrations are common.
