    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.

    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.
