SPIROL’s Slotted Spring Pin offering consists of 1) SPIROL Standard Metric Slotted Pins, 2) SPIROL Standard Inch Slotted Pins and 3) ISO 8752 Slotted Pins. A Slotted Pin is a general purpose low cost component used in numerous fastening applications. Compressed as it is installed, the pin applies continuous pressure towards the sides of the hole wall. The primary spring action of the Slotted Pin is focused on the area opposite the slot as the two halves of the pin compress during installation. This flexibility allows the Slotted Pin to accommodate wider hole tolerances than rigid Solid Pins which results in reduced manufacturing costs of the component.

Otherwise known as Roll Pins, Split Pins, Expansion Pins, Tension Pins or simply Spring Pins, SPIROL’s Slotted Spring Pins are available in high carbon steel and stainless steel in diameters ranging from 1.5mm up to 12mm for metric pins and .062” (1/16) up to .500” (1/2) for inch pins.

SPIROL offers Coiled Spring Pins in light, standard and heavy duty, to match the required strength and flexibility for each application. A pin too strong for the applied force will not flex and could cause damage to the hole. A pin too flexible could prematurely fatigue the assembly. A Coiled Pin with the optimal combination of strength, flexibility and diameter will result in the prolonged useful life of an assembly. Otherwise known as Spiral Pins, Coil Pins, Roll Pins or simply Spring Pins, Coiled Spring Pins are available in both inch and metric sizes in a variety of materials and finishes from .031” (1/32)/0.8mm in diameter up to .750” (3/4)/20mm in diameter. Select from our expansive standard offering, or allow us to work with you to design a custom Coiled Pin to meet your unique requirements!
