SPIROL Standard Slotted Spring Pins
SPIROL 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 for SPIROL Standard Slotted Pins compared to ISO 8752 pins including:
- 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 pins.
SPIROL Standard Slotted Spring Pins can be certified to ASME B18.8.4M (metric) and ASME B18.8.2 (inch). However, the SPIROL Standard Slotted Spring Pin offers enhanced benefits over the ASME specifications in that the pin is rounder, has a better chamfer configuration and end condition.
