Spring Pins & Roll Pins — Slotted and Coiled Pins for Shaft and Linkage Applications
Spring pins (also called roll pins or slotted spring pins) are hollow cylindrical pins with a longitudinal slot that allows them to compress slightly during installation — creating a tight interference fit in the hole without requiring precision-machined clearances. AIMS Industrial stocks metric and imperial roll pins from Champion, GJ Works and Work Shop Buddy in individual sizes and assortment kits.
How Spring Pins Work
The slot in the pin wall allows the pin to compress radially when driven into an undersized hole. The spring tension of the compressed pin locks it in place and provides vibration resistance. Spring pins can be removed and reinserted — making them more reusable than solid dowel pins in applications where disassembly is required.
Metric Spring Pins
Metric roll pins are available in diameter and length combinations from 1.5mm × 5mm through to 10mm × 50mm. Champion stocks individual metric roll pins as well as large and small assortment kits. Work Shop Buddy metric roll pin grab kits (315 pieces) provide a convenient range of sizes for workshop use. Assortment refill packs are available for both standard kit sizes.
Imperial Spring Pins
Imperial roll pins from Champion are available in standard inch-dimensioned sizes for use with imperial-dimensioned shafts and linkages — common in agricultural machinery, older industrial equipment and North American-designed machines.
Applications
Spring pins are used for: shaft-to-hub connections (locking gears, pulleys and collars), pivot pins in linkages, door and hinge pins in panels and enclosures, shear pins in torque-limiting applications, and position pins in jigs and fixtures. They are manufactured to DIN 1481 (slotted spring pin) or ISO 8752 standards.
