    Dowel Pins

    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.

    High-Strength Machinable 416 Stainless Steel—These pins hold their shape under stress and friction from moving parts. In addition to being the strongest stainless steel alloy, 416 is also the most machinable, so you can shape these pins to fit your hole. However, they are the least corrosion-resistant stainless steel option.

    Easy-Install Ring-Grip Locking Quick-Release Pins

    Instead of holding down a button, simply push or pull the head to unlock the two retaining balls. The split ring folds down when these pins are installed to save space, and you can pull with just one finger to remove. Also known as double-acting pins.
    Corrosion-Resistant Stainless Steel with Split Ring
    Image of Product. Front orientation. Contains Annotated. Quick-Release Pins. Easy-Install Ring-Grip Locking Quick-Release Pins, Split Ring.
    Secure the split ring to a lanyard to keep pins from getting lost, or attach tags to identify components.
    High-Strength 17-4 PH Stainless Steel—The strongest stainless steel pins we offer, these are the least likely to deform due to stress and vibration. They resist rust in wet and outdoor environments but won't hold up to the harsh chemicals and acids that 316 stainless steel can.

    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.
    Black-Phosphate-Coated Spring Steel—The dark coating creates both a finished appearance and a barrier against rust that's more durable than clear zinc plating. Stronger than stainless steel, these pins won't deform from stress and vibration.
    Wear-Resistant 400 Series Stainless Steel—Our most wear-resistant stainless steel pins, these are good for pivoting parts that create a lot of friction. They hold up in environments that experience occasional moisture, but they're not as corrosion resistant as 18-8 and 316 stainless steel.

    Undersized Dowel Pins

    You don’t need to create precise holes for these pins when aligning parts you plan to bolt together. They have a slightly undersized diameter to slip into place without the need for special installation tools, like an arbor press. Undersized pins are also used for prototyping and positioning components you need to assemble and disassemble frequently.
    Corrosion-Resistant Stainless Steel
    Image of Product. Front orientation. Dowel Pins. Undersized Tolerance, Plain Head.
    18-8 Stainless Steel—The choice for wet and outdoor environments. In addition to resisting rust, these pins also withstand mild chemicals such as cleaners and degreasers. They are strong enough to join most components but won't withstand extreme stress and vibration as well as steel.

    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.
