SPIROL invented the Coiled Spring Pin in 1948. Coiled Spring Pins are available in three duties to enable the designer to select the right combination of strength, flexibility and diameter to suit different host materials and application requirements. Standard duty Coiled Spring Pins, sometimes referred to as “medium duty”, provide the optimum combination of strength and flexibility in nonferrous and mild steel assemblies. Standard duty Coiled Pins are also recommended in hardened components because of their shock absorbing abilities.
SPIROL offers inch (imperial) standard duty Coiled Spring Pins in diameters ranging from .031” (1/32) up to .750” (3/4). Standard materials include high carbon steel, 302/304 austenitic (nickel) stainless steel, and 420 martensitic (chrome) stainless steel; as well as 6150 alloy steel for diameters .625” (5/8) and larger. Standard duty inch Coiled Pins conform to ASME B18.8.2.
In addition to being able to purchase standard duty Coiled Spring Pins, you are also able to download 2D Sales Drawings and 3D models of all Coiled Pins through our website. Just select the Coiled Pin that you require, and then download the drawing from a choice of 40 different file types.
SPIROL’s standard offering of Coiled Spring Pins can be purchased through eCommerce in standard box quantities. Should you require a different quantity, custom size, special material or finish, please feel free to contact us directly by emailing us at info@spirol.com, calling us at the nearest SPIROL location or submitting your request for quote through the configurator.
