Coiled Spring Pins are available in three duties, light duty, standard duty and heavy duty, to match the strength and flexibility required for each application. A pin too strong for the applied load will not flex and may cause damage to the hole. A pin too flexible may prematurely fatigue in the assembly. The Coiled Pin with the optimal combination of diameter, strength, and flexibility will extend the useful life of the assembly. Light duty Coiled Spring Pins are generally recommended for use in soft or brittle materials, or where the hole is located close to the edge of an assembly. In assemblies not subjected to high forces, light duty Coiled Pins are a great choice as installation will be easier due to their lower insertion forces.

SPIROL’s light duty inch Coiled Spring Pins conform to ASME B18.8.2 and are available in diameters ranging from .062” (1/16) up to .250” (1/4). Light duty pins are also available in Ø.312” (5/16) upon request. Standard materials include high carbon steel, 302/304 austenitic (nickel) stainless steel and 420 martensitic (chrome) stainless steel.

In addition to being able to purchase light 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, or submit your request for quote through the configurator.
