The Coiled Spring Pin was invented by SPIROL in 1948. SPIROL offers Coiled Pins in three duties, light, standard and heavy, to provide a variety of combinations of strength, flexibility and diameter to accommodate different host materials and applications. A pin too More... strong for the applied force may not flex and may cause damage to the hole. A pin too flexible in the assembly may prematurely fatigue. The goal is to optimize the combination of strength, flexibility and diameter of the Coiled Pin to maximize the useful life of the assembly. Light duty Coiled Spring Pins are recommended for use in soft or brittle materials, or where the hole is located close to the edge of an assembly. Light duty Coiled Pins are also a great choice for assemblies not subjected to high forces as installation will be easier due to their lower insertion forces.SPIROL’s light duty metric Coiled Springs are available in diameters ranging from 1.5mm up to 6mm as a standard, and are available to order in Ø8mm. Light duty Coiled Pins are manufactured from high carbon steel, 302/304 nickel (austenitic) stainless steel and 420 chrome (martensitic) stainless steel and conform to both ISO 8751 and ASME B18.8.3M.In addition to being able to purchase light duty metric Coiled Spring Pins online, you may also download 2D Sales Drawings and 3D models of all Coiled Pins by simply selecting the Coiled Pin that you require, and downloading the drawing in the desired file type. 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.

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 More... 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.

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 More... 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 PinSPIROL’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.

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 More... 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).

SPIROL’s Standard Metric Slotted Spring Pins have a number of advantages compared to Slotted Pins produced to the ISO 8752 specification:Slot width narrower than the wall thickness, thus preventing the pins from nesting or interlocking. Smaller expanded (pre-insertion) More... diameter which results in lower insertion force and smoother insertion.Rounder pins, which in turn results in better conformance of the pin to the hole wall and eliminates the edge of the slot damaging the hole during insertion.Lower stress in the spine of the installed pin. This results in longer pin life in shock or fatigue applications.Ability to use automatic vibratory feeding of pins for installation without interlocking.Plating of pins for additional corrosion resistance or appearance without “touch marks” or the bonding of nested pinsFor more information about the benefits of the SPIROL Standard Slotted Pin over ISO 8752, click hereSPIROL’s Standard Metric Slotted Pins meet or exceed ASME B18.8.4M Type B specifications and are available in high carbon steel, nickel (austenitic) stainless steel and chrome (martensitic) stainless steel in diameters ranging from 2mm to 12mm.In addition to being able to purchase or request a quote for SPIROL’s standard Slotted Spring Pins online, you are also able to view or download 2D drawings and 3D models of all available Slotted Pins.

SPIROL’s Standard Slotted Spring Pins have a slot width narrower than the wall thickness and thus do not nest or interlock. SPIROL’s Standard Inch Slotted Spring Pins are produced with state-of-the-art technology resulting in lower insertion force, smoother More... insertion, and rounder outside diameters as compared to Slotted Pins produced with traditional methods. The edge of the slot on SPIROL’s Standard Slotted Pin does not damage the hole during installation, and there is lower stress in the spine of the installed pin resulting in longer pin life when subjected to shock and vibration. Since these Slotted Pins do not interlock, they are conducive for automatic feeding. SPIROL’s Standard Inch Slotted Pins meet or exceed ASME B18.8.2 specifications and are available in high carbon steel, nickel (austenitic) stainless steel and chrome (martensitic) stainless steel in diameters ranging from .062” (1/16”) to .500” (1/2”).In addition to being able to purchase or request a quote for SPIROL’s standard Slotted Spring Pins online, you are also able to view or download 2D drawings and 3D models of all available Slotted Pins.
