Zinc-Plated Carbon 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.

Zinc Yellow-Chromate-Plated Carbon Steel—With a more durable finish than clear zinc plating, these pins hold up in wet and outdoor environments although not as well as stainless steel. Because the plating resists wear and the steel holds up under stress, they're good for pivoting parts, like rod end linkages.

Painted Carbon Steel—Stronger than stainless steel, these pins won't deform from stress and vibration. The dark enamel creates a finished look but offers minimal corrosion resistance. They're best for dry environments.

Cotter Pin Included—The hairpin cotter is quicker to install and remove than a linch pin but not as secure.

Linch Pin Included—Less likely to get knocked or shaken out of place than a hairpin, the linch pin has a ring that snaps down and locks.

17-4 PH Stainless Steel—The strongest stainless steel pins we offer, these are the least likely to deform due to stress and vibration. Similar to 18-8 stainless steel, they're suitable for most wet and outdoor environments. However, they won't hold up to the harsh conditions and chemicals that 316 stainless steel can.
