Heavy Duty Spring Pins

(ISO 8752 / DIN 1481 – Coiled Spring Pins)

The ISO 8752 standard heavy duty spring pin, also known as a coiled spring pin, features a thicker wall and enhanced elasticity compared to standard spring pins (such as JIS B 2808). This structure provides higher shear strength and improved resistance to deformation, making it ideal for high-load and high-impact applications.

Its multi-turn coil construction ensures consistent fastening under cyclic stress and prevents loosening or pin failure. These pins are widely used in heavy machinery, mechanical assemblies, and automated components requiring robust load-bearing capability.
