Spiral Spring pins are manufactured to an oversize dimension so that when the pin is inserted into a hole, radial forces are generated against the hole wall holding the spring pin securely in place. Spring pins are classified into two types: slotted pins and coiled pins.

 

Slotted Spring Pins

The sheet material in a slotted pin is curled around by less than 360 degrees, allowing a gap into which the pin can collapse. These pins are commonly utilized in lighter-duty applications or when stiffness is required.

 

Spiral Spring Pins

A spiral pin is often formed of a lighter gauge of sheet material than a slotted pin, but it is twisted around by more than two full rotations. As a result, the pin is powerful while being flexible. This has the potential to lower stress concentrations and fatigue failures.

 

Our coiled spring pins or spiral pins are made of alloy steel for high tensile strength and resistance to wear and fatigue. They are available in a variety of finishes, including black oxide, zinc-plated, and uncoated. They come in a variety of diameters and lengths, making it simple to find the correct coiled spring pin for your needs.
