  • Heavy Duty Coiled Spring Pins

SPIROL’s heavy duty metric Coiled Spring Pins range in diameter from 1.5mm up to 12mm, and are available in larger diameters up to 20mm by request. Standard materials are high carbon steel, 302/304 nickel (austenitic) stainless steel and 420 chrome (martensitic) stainless steel. Diameters larger than 12mm are available in 6150 alloy steel. SPIROL’s heavy duty metric Coiled Spring Pins conform to both ISO 8748 and ASME B18.8.3M.

Coiled Spring 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.

In addition to being able to request a quote or purchase heavy duty Coiled Spring Pins, you may also download 2D Sales Drawings and 3D models of all Coiled Pins through this website. Simply select the Coiled Pin that you require, and then download the drawing from a choice of 40 different file types.

If you require different quantities, custom sizes, special materials and finishes, please contact SPIROL directly at info@spirol.com, call any one of our global offices or request your requirements through the online configurator.
