Light duty – spring pins have a longitudinal slot along one side. Compressed as installed, the pins apply continuous pressure towards the sides of the hole wall. 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.

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.

316 stainless steel pins have the best corrosion resistance of our stainless steel pins, and are as strong as 18-8 stainless steel pins.

400 series stainless steel pins resist wear from abrasion and have some 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.
