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.
