    Cotter Pin Type

    Cotter Pin Type

    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.

    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.

    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.

    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.

    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.

    Cotter Pins

    Lock the ends of clevis pins and shafts to keep components in place. Slide these cotter pins into a hole and then bend the prongs outward with pliers to secure. Also known as split pins, one prong is slightly longer than the other for easy opening once inserted. Repeated bending will weaken the pin, so they should not be reused.

    Carbon 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.
    Zinc-Plated Carbon Steel and 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.

    Hairpin Clips

    Image of ProductInUse. Front orientation. Cotter Pins. Hairpin Clips.
    Snap these clips into a grooved shaft or clevis pin instead of inserting through a hole. They're an alternative to retaining rings for easy installation since you can install and remove by hand. Clips are reusable like retaining rings but more likely to loosen from vibration.

    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.

    Long-Life Wire-Snap Cotter Pins

    Disassemble components frequently without losing tension in the pin. The coil preserves holding strength, so you can reuse these pins over and over. They also offer more security than hairpins and standard wire-snap pins. Also known as safety pins, pinch firmly to open and close.

    These pins come in a range of sizes to fit various clevis pin diameters, and you can install them in a single step. One prong is already bent, so just push them into a hole and pins stay in place to secure components. Although hairpins are reusable, they don’t withstand vibration as well as standard cotter pins. Also known as hitch pin clips and R-clips.

    Push or pull these pins into either side of the hole. The double-head design clinches them around a shaft, so there’s little chance they will get shaken or knocked out of place. Bow-tie pins are quicker to install and remove than wraparound pins but are not quite as secure. Like wraparound pins, these are reusable.

    Mil. Spec. Cotter Pins

    These pins are manufactured and tested to strict U.S. military standards for material and construction. They lock the ends of clevis pins and shafts to keep components in place. Slide pins into a hole and then bend the prongs outward with pliers to secure. Also known as split pins, one prong is slightly longer than the other for easy opening once inserted. Repeated bending will weaken the pin, so they should not be reused.

    Unlike standard cotter pins, you only need access to one side of these pins to install. They’re often used where obstructions make it difficult to reach around a clevis pin or locknut to secure it. Strike the head to drive them through a hole and force the prongs apart. Once installed, these pins are permanently bent and can’t be reused.

    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.

    Keep a range of sizes on hand to lock the ends of clevis pins and shafts and keep components in place. Slide these cotter pins into a hole and then bend the prongs outward with pliers to secure. Also known as split pins, one prong is slightly longer than the other for easy opening once inserted. Repeated bending will weaken the pin, so they should not be reused.
    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.
    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.

    Even under extreme stress and vibration, these heavy duty pins won’t work their way out of a hole. The wedge-lock design withstands the most demanding applications, including securing railcar wheels. You only need access to one end of the pin to install. Slide into a hole and then hit the head with a hammer to wedge the prongs open. Once installed, these pins are permanently bent and can’t be reused.

    Carbon 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.
