Heavy Duty Coiled Spring Pins SPIROL’s heavy duty Coiled Spring Pins are available in diameters ranging from 1.5mm (.062") up to 20mm (.750"). Standard materials include high carbon steel, 302/304 nickel (austenitic) stainless steel, and 420 chrome (martensitic) stainless steel. Diameters larger than 12mm (.500") are available in 6150 alloy steel. SPIROL invented the Coiled Spring Pin in 1948. Coiled Pins are available in light duty, standard duty and heavy duty to match the required strength and flexibility for each application. A pin too strong for the applied load will not flex and may damage the hole. A pin that is too flexible may fatigue prematurely within the assembly. The Coiled Pin with the optimal balance of strength, flexibility and diameter will result in the prolonged useful life of the assembly. Generally, heavy duty Coiled Spring Pins are recommended for use in hardened materials where design limitations restrict the use of a larger diameter standard duty Coiled Pin.
