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.

Squeeze pins closed and install them in a hole slightly smaller than the pin. Tension holds them tight against the hole wall. The chamfered ends aid insertion.

Breaking strength is measured as double shear, which is the force required to break a pin into three pieces.
