  • Heavy Duty Coiled Spring Pins

SPIROL offers Coiled Spring Pins in three different duties, light duty, standard duty and heavy duty, to match the required strength and flexibility for each application. A pin too robust for the applied force will not flex and can cause damage to the hole. A pin too flexible could prematurely fatigue in the application. The Coiled Pin with the optimal combination of strength, flexibility and diameter will result in the prolonged useful life of an assembly. Heavy duty Coiled Spring Pins are generally recommended for use in hardened materials where space or other design limitations prohibit the use of a larger diameter standard duty Coiled Pin

SPIROL’s heavy duty inch (imperial) Coiled Spring Pins conform to ASME B18.8.2 and are available in standard diameters ranging from .062” (1/16) up to .500” (1/2). Standard materials include high carbon steel, 302/304 austenitic (nickel) stainless steel and 420 martensitic (chrome) stainless steel. Larger diameters of .625” (5/8) and .750” (3/4) are available upon request in 6150 alloy steel.

In addition to being able to purchase heavy duty Coiled Spring Pins online, you are also able to view or download 2D Sales Drawings and 3D models of all Coiled Pins simply by selecting the Coiled Pin that you require, and then downloading the drawing in the desired file type.

Should you require a custom size, special material or finish, or different quantity, please feel free to contact us directly at info@spirol.com, call us at any one of our global offices or submit your request for quote through the online configurator.
