Material:Zinc-plated, Nickel-plated, Natural color, Black oxide

Size:D 0.8-16mm or Custom

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 slightly smaller than the pin. 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.

Coiled Spring Pins are often used as hinge pins or alignment dowels, or to fasten two or more components to each other – such as a gear to a shaft. Coiled Spring Pins were specifically designed to address deficiencies associated with conventional methods of fastening such as threaded fasteners, rivets and other types of pins subject to lateral forces. Easily recognized by its unique coil cross section, Coiled Pins are retained by radial tension when installed into the host component, and they are the only pins with uniform strength and flexibility after insertion. Otherwise known as Spiral Pins, Coil Pins, Roll Pins, or simple Spring Pins, Coiled Spring Pins are available in both inch and metric sizes in a variety of materials and finishes from 0.8mm diameter up to 16mm in diameter. The Coiled Pin is available in three “duties” to allow choice for the optimum combination of strength, flexibility and diameter to suit different host materials and application requirements.
