Coiled spring pin / headed
Coiled Spring Pins are shock-absorbing fasteners that supply mobility, consistent energy, similar strain distribution, better size tolerances, no interlocking, trouble-free computerized feeding, and also reduce cost.
Series 410 is a flared headed pin used when retention to the very end of the pin or absolute limitation of movement in one direction is required. The flare also facilitates removal from a blind hole. A hole with a countersink is required for flush insertion.
