Coiled Spring Pins

End View

These spiral pins remain flexible after installation, so they absorb shock and vibration better than slotted spring pins. They work well in holes that are out of round. Use them for fastening, pivoting, and holding.

Squeeze pins closed and install them in a hole. Tension holds them tight against the hole wall. The chamfered ends aid insertion.

Breaking strength is measured as double shear, which is the force required to break a pin into three pieces.

Steel pins offer good strength.

Inch pins meet ASME B18.8.2 specifications for material and dimensions. Metric pins meet either ISO 8748 or ISO 8750 specifications.

Heavy Duty Coiled Spring Pins

End View

For tough jobs, these spiral pins are 30% stronger than our standard coiled spring pins. They remain flexible after installation to absorb shock and vibration, and work well in holes that are out of round. Use them for fastening, pivoting, and holding.

Squeeze pins closed and install them in a hole. Tension holds them tight against the hole wall. The chamfered ends aid insertion.

Breaking strength is measured as double shear, which is the force required to break a pin into three pieces.

All pins meet ASME specifications for material and dimensions. Metric pins also meet ISO 8748 specifications.

Steel pins offer good strength.

Coiled Spring Pin Assortments

Coiled spring pins are flexible after installation, so they absorb shock and vibration better than slotted spring pins. They also have higher dynamic load capacities and accommodate wider hole tolerances. Actual diameters are slightly larger than the diameters shown, allowing pins to fit tightly when installed.
