    Squeeze these pins into holes and they expand slightly, creating tension to hold parts in place. They are often used as hinge pins and as fasteners for springs and power transmission components. An alternative to dowel pins, they're lighter in weight with a hollow center and don’t need a precise hole. Also known as roll pins.
    Breaking strength is measured as double shear, which is the amount of force required to break a pin into three pieces.
    Spring Steel—These pins won't deform from stress and vibration. Although they're stronger than stainless steel, they're best for dry environments since moisture will cause them to rust.

    Cotter Pins
    3D CAD models available

    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.

    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.
