Hairpin Cotter Pins

Secure components more quickly than standard cotter pins. One prong is already bent, so just push into a hole for installation in one step. Although hairpins are reusable, they don’t withstand vibration as well as standard and hammer-set cotter pins. Also known as hitch pin clips and R-clips.

Steel

Zinc-Plated Spring Steel—These pins withstand occasional exposure to moisture. However, since friction from moving parts can wear away the finish, they're not ideal for wet environments. While not nearly as corrosion resistant as stainless steel, they are stronger and won’t deform under stress.

Spring Steel—Stronger than stainless steel, these pins won't deform from stress and vibration. They perform best in dry environments since moisture will cause them to rust.

Corrosion-Resistant Stainless Steel

18-8 Stainless Steel—The choice for wet and outdoor environments, these pins resist rusting. They are strong enough to join most components but won't withstand extreme stress and vibration as well as steel.

Highly Corrosion-Resistant 316 Stainless Steel—Superior to 18-8 stainless steel, these pins won't degrade when exposed to harsh weather, salt water, and most chemicals. They're strong enough to join most components but won't withstand extreme stress and vibration as well as steel.

Long-Life Hairpin Cotter Pins

You can use these pins over and over without reducing their hold, and they're quicker to install than standard cotter pins. One prong is already bent, so just push into a hole to secure parts in one step. Although the coil maintains tension, hairpins don’t withstand vibration as well as standard and hammer-set cotter pins. Also known as hitch pin clips and R-clips.

Steel

Spring Steel—Stronger than stainless steel, these pins won't deform from stress and vibration. They perform best in dry environments since moisture will cause them to rust.
