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. 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. Often referred to as a 'spiril' pin in the Midlands.
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.
Standard duty coiled spring pins offer the best balance between flexibility and strength and are recommended for most applications.
Heavy duty coiled spring pins are typically used in high shear strength applications and hardened host materials.
Light duty pins are used in applications with soft metals and plastics holes where there is a high risk of enlarging or breaking the host using a traditional press fit solid pin.
