    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.

    Parallel Groove

    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.
    Material Certificate—Pins include a report with a traceable lot number and a description of their chemical, physical, and mechanical properties.
