Slotted Spring Pins are general purpose low cost components 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.
SPIROL’s Slotted Spring Pin offering consists of 1) SPIROL Standard Metric, 2) SPIROL Standard Inch and Slotted Pins per 3) ISO 8752. SPIROL’s standard Slotted Spring Pins have a slot width narrower than the wall thickness and thus do not nest or interlock. This feature, combined with a smaller expanded (pre-insertion) diameter, results in a number of advantages compared to ISO 8752 pins:
SPIROL offers a comprehensive line of commercial (ASME and ISO) and military (MS/NASM and NAS) standard Slotted Pins ranging from 1.5mm / .062”(1/16”) to 12mm / .500” (1/2”) in high carbon and stainless steels.
SPIROL also designs and manufactures Pin Installation Equipment, from manual to fully automatic modules. Learn more about SPIROL’s Pin Installation Equipment, or contact us for support in determining the best pin for your application.
