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.

The Series 500 Extra Light Duty Coiled Pins were specifically designed for use in soft or fragile materials. The 1½ coil formation ensures that the radial force exerted against the hole wall does not exceed the strength of the hole material to prevent deformation. These pins are also an economical solution where pin strength is not a major design consideration. Typical applications for Series 500 Extra Light Duty Pins include: hinge pins in plastic or ceramic assemblies, alignment pins, and fastening applications where the hole is close to an edge of an assembly component.

SPIROL's Series 600 Superflex Coiled Pin has a loosely wrapped outer coil and a diameter at 90° to the seam equal to the hole size to provide a low insertion force and enhanced flexibility after insertion. The Superflex Pin eliminates insertion problems associated with hardened holes with sharp edges. A Superflex Coiled Pin is not distorted during insertion and maintains its straightness. One example of a great application for the Superflex Pin is when the pin is inserted into a shaft with both ends exposed for engagement into a slotted clutch component.
