    Compare drilling, pointed, thread-forming, and thread-cutting tips to find the best choice for your material.

    Steel Flanged Hex Head Thread-Cutting Screws

    Image of Product. Front orientation. Tapping Screws. Steel Flanged Hex Head Thread-Cutting Screws.
    Cut threads into drilled holes in metal using a nutdriver or socket. Because these screws remove material, they take less effort to install and put less stress on your workpiece than thread-forming screws. The flanged hex head gives you a high-torque grip and spreads the load to prevent crushing thin metal.
    Length is measured from under the flange. Head height includes the flange.
    Zinc-Plated Steel—A common choice for areas with occasional exposure to moisture.

    Serrations on the flange grip material for a tighter, more vibration-resistant hold than other tapping screws. Turn with a nutdriver or socket to cut threads into drilled holes in metal. Because they remove material, they take less effort to install and put less stress on your workpiece than thread-forming screws. The flanged hex head gives you a high-torque grip and spreads the load to prevent crushing thin material.
    Length is measured from under the flange. Head height includes the flange.
