    Split Rings

    Image of Product. Front orientation. Contains Annotated. Split Rings.
    Also known as key rings, twist these rings into place to secure clevis pins, connect components, or add a pull handle. They don't have the sharp ends of other cotter pins.
    Rings with a length and width are 50% stronger than those with similar ODs and IDs.
    Zinc-Plated Carbon Steel—Zinc-plated carbon steel rings have good strength and some corrosion resistance.
    18-8 Stainless Steel—18-8 stainless steel rings offer a balance of strength and corrosion resistance. They may be mildly magnetic.
    316 Stainless Steel—316 stainless steel rings have the best corrosion resistance of our stainless steel split rings, and are as strong as 18-8 stainless steel pins. They may be mildly magnetic.
    260 Brass—260 Brass rings are rust resistant, electrically conductive, and nonmagnetic.

    Coiled Cotter Pins

    Free of sharp ends, these pins secure components without snagging or cutting surrounding material. They are similar to split rings but easier to install—just insert the center prong into the hole and twist. Although coiled pins are reusable, they won’t withstand vibration and stress as well as other cotter pins.

    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.
