SPIROL invented the Coiled Spring Pin and its production technology in 1948. Since that time, the Coiled Spring Pin has proven to be the most versatile spring pin in the industry. More than fasteners, SPIROL Coiled Pins are shock-absorbing elements that are integral, active components of a total assembly. A problem solver, SPIROL Coiled Pins offer the lowest installed cost in most applications.
Standard SPIROL® Coiled Spring Pins provide flexibility, uniform strength, equal stress distribution, closer diameter tolerances, no interlocking, trouble-free automatic feeding, and they reduce costs. Heavy, standard, and light duty pins provide combinations of strength, flexibility and diameter to meet the specific engineering objectives of your pinning applications.
Otherwise known as Spiral Pins, Coil Pins, Roll Pins or simply Spring Pins, Coiled Spring Pins are available in both inch and metric sizes in a variety of materials and finishes from 0.8mm/.031” (1/32) in diameter up to 20mm/.750” (3/4) in diameter.
