    Hex-Bit Taps

    Image of Product. Front orientation. Taps. Hex-Bit Taps.
    You only need one tool to turn these taps and install screws. The 1/4" hex shank fits hand or powered screwdrivers for threading holes. Then switch to a screwdriver bit to finish the job. To tap in hard-to-reach spots, add a bit extension. Taps have straight flutes that are good for most jobs.
    High-Speed Steel—The most versatile taps resist heat and wear to stay sharp. They’re good for most metals and plastic.
    Uncoated—The economical choice, these won't last as long as coated taps.
    Plug Chamfer—Our go-to chamfer type, these thread both through holes and blind holes. The tapered section is shorter than a taper chamfer and longer than bottoming chamfer. As a result, they're easier to turn than bottoming taps but require more force than taper taps.
