Spirol Spring Pins are roll formed metal strips coiled 2.25x. They are used to align and secure components relative to one another. The resting diameter of the pin is larger the hole diameter into which it is to be inserted. When inserted into the hole the spring action of the pin compresses to fit the smaller diameter hole. As the pin tries to expand to the original diameter the force against the hole’s wall tightens the fit. This creates the holding power against shock and vibration. The ends are chamfered to make insertion of the pin easier.
