    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.

    Calibration Rods

    Also known as calibration standards, these rods let you check and set micrometers and other measuring tools. For accuracy, they’re precision ground to extremely tight length tolerances. They have insulated plastic handles to minimize heat expansion.

    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.

    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.
