Only Coiled Pins utilize the coiled spring concept; a recognized superior pin design. This imparts to SPIROL Coiled Spring Pins unique features not found in other Spring Pins or Solid Pins. More than fasteners, SPIROL Coiled Pins are shock-absorbing elements that are integral, active components of a total assembly. There are other pinning methods, but when the total assembly’s manufacturing cost, quality and useful life are important, the pin of choice is the SPIROL Coiled Spring Pin.
SPIROL provides general design guidelines and complimentary Application Engineering support to help you design your assembly to achieve the desired form, fit and function for the life of the product.
Take advantage of SPIROL’s complimentary Application Engineering support to help you select the proper Coiled Pin to meet both your application and assembly requirements.
