SPIROL's Coiled Spring Pin were specifically designed to address deficiencies associated with conventional methods of fastening such as threaded fasteners, rivets and other types of pins subject to lateral forces. Easily recognized by its unique 2¼ coil cross section, Coiled Pins are retained by radial tension when installed into the host component, and they are the only pins with uniform strength and flexibility after insertion. The Coiled Pin is available in three “duties” to allow choice for the optimum combination of strength, flexibility and diameter to suit different host materials and application requirements.
