Slotted Spring Pins
Also known as roll, tension, split, and expansion pins, these pins have a slot along one side that you squeeze closed to install them into unthreaded holes. Once installed, they expand slightly, creating outward tension that holds them tight against the hole wall. These pins absorb shock and vibration in your system, and keep parts from loosening. They are often used as hinge pins, or to hold springs and power transmission components in place.
Install these pins into a hole slightly smaller than the pin diameter. They have at least one chamfered end, which means the end is angled to make insertion easier.
Breaking strength is measured as double shear, which is the amount of force required to break a pin into three pieces.
Steel pins are strong and wear resistant. Pins with a black-phosphate or zinc-plated finish have an outer layer to protect the steel underneath from rust.
18-8 stainless steel pins offer a balance of strength and corrosion resistance.
420 stainless steel pins are as strong and wear resistant as steel, with the addition of corrosion resistance in wet environments.
Passivated pins offer added protection against corrosion and oxidation.
Pins that meet ASME B18.8.2 specifications are made to ASME standards for material and dimensions.

Coiled Spring Pins
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.
Steel pins offer good strength.
420 stainless steel pins resist wear as well as corrosion. They are magnetic.
Passivated pins offer added protection against corrosion and oxidation.
Inch pins meet ASME B18.8.2 specifications for material and dimensions.
