    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.
    Steel
    High-Strength Alloy Steel—Our strongest, most wear-resistant pins, these won't bend or break from vibration. 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.

    Cut this stock to the length you need.
    Steel has good strength. Stainless steel is more corrosion resistant than steel.
    M2 High-Speed Tool Steel—M2 high-speed tool steel is harder than 4140 alloy steel for better wear resistance.
    18-8 Stainless Steel—18-8 stainless steel offers a balance of strength and corrosion resistance. It may be mildly magnetic.
    316 Stainless Steel—316 stainless steel has the best corrosion resistance of our stainless steel dowel pin stock. It may be mildly magnetic.
    416 Stainless Steel—416 stainless steel is more wear-resistant than other stainless steel. It has some corrosion resistance and is magnetic.
    17-4 PH Stainless Steel—17-4 PH stainless steel is our strongest stainless steel dowel pin stock. It has some corrosion resistance and is magnetic.

    Clevis Pins

    The most commonly used clevis pins—just slide a cotter pin into the hole to secure parts. These pins have a flat, low-profile head to fit in tight spaces. They're less likely to get in the way than pins with a loop grip or T-handle but aren’t as easy to grab if you want to remove them frequently. Add your own cotter pin, or choose a clevis pin that includes a reusable hairpin cotter.

    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—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.
