Pins

Grooved Pins are solid and cylindrical with three longitudinal grooves, manufactured from bar or coil stock. The three grooves are pressed into the cylindrical body to expand its diameter to a size greater than its nominal diameter in a precisely controlled way. Material is displaced, but not removed, from the pin the process. This works by pressing the pin into a hole the size of the nominal diameter, the constraining action of the hole compresses the expanded material in a spring-like manner and produces a holding force. This unique locking action is accomplished without permanent deformation of either the base material or the pin. Pins have several advantages: They provide excellent holding power in cases of severe vibration and shock, even in the case of axial displacement. They require only a straight-drilled hole and may be driven with a hammer, air cylinder or hydraulic press. They allow easy installation and quick assembly. Pins can be removed and reused.
