    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.

Use them for high-stress applications, such as mounting and aligning hydraulic cylinders and injection molds. They perform best in dry environments since moisture will cause them to rust.

    Corrosion-Resistant Stainless Steel
    Image of Product. Front orientation. Dowel Pins. Standard 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.
    Highly Corrosion-Resistant 316 Stainless Steel—Our most corrosion-resistant pins, these hold up in just about any environment. They won't degrade from exposure to weather, salt water, and most chemicals. Like 18-8 stainless steel, they're strong enough to join most components but won't withstand stress and vibration as well as steel.
    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.

    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.

    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.

    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.

    The best spring pins for joining parts exposed to vibration and shock. They're often used in power transmission, automation, and other assemblies with constant motion and sudden starts and stops. Because of their spiral shape, they flex to conform to holes that aren’t perfectly round.
    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.

    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.

    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.

    Partially Grooved Dowel Pins

    The grooved section secures these pins while the smooth portion is free to act as a pivot or hinge. The grooves pinch shut when installed, creating tension to lock in place. They fit tighter than standard dowel pins and resist pulling from movement and vibration, even in imperfect holes.
    For the best fit, drill your hole slightly larger than the nominal diameter shown.

    Reverse-Tapered

    Groove

    The most versatile partially grooved pins, these are used in a range of applications, including as rod end linkages, stop pins, and locators. Also known as type H pins.
    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.
    Tapered Groove—Easier to install than pins with parallel grooves but less secure in high-vibration applications.
    Reverse-Tapered Groove—With grooves that narrow toward the end, these pins are the best for securing a stop or handle in a blind hole. They’re easier to insert than pins with parallel grooves but are less secure in high-vibration applications.

    Parallel Groove

    These pins lock in the middle, leaving two smooth ends free. They're often used to create a T-handle, such as on a valve stem to open and close it by hand. Also known as type E pins.
    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.
    Parallel Groove—Fit tighter than pins with tapered grooves to stay in place under severe vibration. However, they require more force to insert.

    Fully Grooved Dowel Pins

    With a tighter fit than standard dowel pins, these resist pulling from movement and vibration, even in imperfect holes. Three grooves pinch shut when installed, creating tension to lock in place. Also known as Type A pins.
    For the best fit, drill your hole slightly larger than the nominal diameter shown.
