Coil Pins (Spiral Pins)
A coiled spring pin, also known as a spiral pin, is a self retaining engineered fastener manufactured by roll forming metal strip into a spiral cross section of 2-1⁄4 coils. They are related to the split roll pin which serves the same purpose.
Coiled spring pins have a body diameter larger than the recommended hole diameter and chamfers on both ends to facilitate starting the pin into the hole, the spring action of the pin allows it to compress as it assumes the diameter of the hole.
When coiled spring pins are installed, the compression starts at the outer edge and moves through the coils toward the center. Coiled pins continue to flex after insertion when a load is applied to the pin thus providing excellent performance to counter fatigue in dynamic applications.
Coiled pins are commercially available in standard duty [this is what we provide] (ISO 8750), heavy duty (ISO 8748), and light duty (ISO 8751), which provide for a variety of combinations of strength and flexibility to suit different performance requirements. Typical materials for coiled spring pins include steel and stainless.
