    Dowel Pins

    Image of Product. Front orientation. Dowel Pins. Plain Head, Standard Tolerance.
    Precisely align machine parts and prevent movement during assembly. These dowel pins are machined to tight tolerances and have a uniform diameter for a snug fit. They can also be used as a pivot, shaft, or hinge to join moving components. Since dowel pins can be hard to remove, they are best suited for permanent fixtures that don't require frequent adjustments or disassembly.
    Nickel
    Corrosion-Resistant 400 Nickel—Also known as Monel, 400 nickel is an economical alternative to titanium. These pins are just as corrosion resistant to stand up to strong acids and harsh chemicals, but they aren't as strong.

    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.

    Corrosion-Resistant 400 Nickel—The best of both worlds, these pins combine the strength of steel with the corrosion resistance of 316 stainless steel. Also known as Monel.

    Machine Key Stock

    Cut this square or rectangular key stock to length to create a straight machine key. Straight keys are the most common type of key. Machine keys are often the same material as the shaft and other components with which they are used. To use a key as a sacrificial part, choose a softer key that will shear off when parts are exposed to excessive force, preventing damage to expensive equipment.
    400 Nickel
    Image of Product. Front orientation. Machine Key Stock. Machine Key Stock.
    400 nickel key stock is the most corrosion resistant key stock in our offering and can be used in highly corrosive environments, such as those involving salt water, sulfuric acid, and alkalies. For complete corrosion resistance, 400 nickel keys are typically used with 400 nickel machine parts. Comparable to Monel, 400 nickel is also known for its strength and weldability.
    Undersized Tolerance—Slightly smaller than the size listed in the table, undersized stock is the choice when you need a slightly looser fit or when you have an inconsistent keyway. Use it when parts need to be taken apart frequently, such as for maintenance or prototyping.
