Product Details

Coiled Spring Pins are multi-layer rolled fasteners where the pin material is wound into multiple coils, providing superior flexibility, shock absorption, and fatigue resistance compared to single-layer slotted spring pins. The coiled construction distributes stress evenly across the pin wall, allowing repeated installation and removal without loss of retention force.

Manufactured to ISO 8750 / DIN 7344 standard from high-carbon spring steel or stainless steel, these pins are the preferred choice for high-vibration, dynamic load, and precision alignment applications in automotive, aerospace, electronics, and heavy machinery industries.

The chamfered ends facilitate easy insertion, while the constant radial spring force ensures a secure, self-retaining fit in the host material without additional locking hardware.
