    Fully Grooved Dowel Pins with Rounded Head

    The domed head creates a finished appearance, so these pins are often used to attach brackets, knobs, and machine plates. The grooves pinch shut when you press pins into a hole, creating tension to lock them in place.
    For the best fit, drill your hole slightly larger than the nominal diameter shown.

    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.

    Undersized Hardened Multipurpose M2 High-Speed Tool Steel Rods

    Image of Product. Front orientation. Steel. Undersized Hardened Multipurpose M2 High-Speed Tool Steel Rods.
    These rods, also known as drill blanks, have an undersized diameter for machining your own drill bits. They're hardened for increased abrasion and impact resistance. M2 tool steel offers a nice balance of wear resistance and machinability. It has a high molybdenum content, which allows it to maintain sharp cutting edges even at elevated temperatures.
