    Square Bits

    Well suited for woodworking tasks, these bits generate just enough force to drive screws into tough materials without risking cracks or splits. Also known as Robertson bits.
    Hex Shank—Also known as insert bits, these snap into hand tools. If you want to use them with power tools, attach a bit adapter (not included).
    Quick-Change Hex Shank—Lock these bits directly into power tools. They won't wobble as much as bits paired with an adapter, so they are the best choice for high-precision tasks.
    Steel—Best for dry environments, since moisture will cause these bits to rust.

    These bits fit around the security pin to turn tamper-resistant square screws. Use them to unlock electronic enclosures and other access-controlled equipment. They withstand more torque than tamper-resistant Phillips bits but not as much as tamper-resistant hex.
    Quick-Change Hex Shank—Lock these bits directly into power tools. They won't wobble as much as bits paired with an adapter, so they are the best choice for high-precision tasks.
    Steel—Best for dry environments, since moisture will cause these bits to rust.

    Screwdrivers

    Ultra Grip

    A staple in any toolbox, these are your go-to screwdrivers for routine maintenance and repair.
    Ultra Grip—Designed for maximum comfort and control. The soft plastic coating and contoured shape reduce strain to prevent cramping and soreness during repetitive tasks. They also guarantee a secure grip.
    Chrome-Plated Steel—The bright, shiny plating resists salt water and chemicals better than other finishes and is less likely to wear off.
    Corrosion-Resistant Stainless Steel—With solid stainless steel construction, these screwdrivers have no coating that could flake off and damage the screw drive. They resist salt water and chemicals better than steel screwdrivers, but are not quite as strong.

    Hex Shank

    Image of Product. Quick-Change Hex Shank. Front orientation. Screwdriver Bits. Square Bits For Impact Drivers, For Power Tools.

    Quick-Change Hex Shank

    Tougher than your average square bits. These have a thin, flexible section on the shank that absorbs 30 times the impact force. They are heat treated for hardness and manufactured to tight tolerances, so they won't snap or slip under high stress.
    Hex Shank—Use a bit adapter (not included) to attach these bits to power tools.
    Quick-Change Hex Shank—Lock these bits directly into power tools. They won't wobble as much as bits paired with an adapter, so they are the best choice for high-precision tasks.
    Steel—Best for dry environments, since moisture will cause these bits to rust.
    Wear-Resistant Diamond-Coated Steel—Diamond particles embedded in the tip bite into the screw head for a strong grip. Our most wear-resistant bits, these maintain their grip and shape, even when driving screws into tough materials.

    One bit, multiple fits. These turn both square and Phillips screws for flexible fastening options. If you need to apply a lot of torque, however, it's best to pair them with square/Phillips screws to avoid slipping and stripping the recess. Also known as Quadrex bits.
    Hex Shank—Also known as insert bits, these snap into hand tools. If you want to use them with power tools, attach a bit adapter (not included).
    Quick-Change Hex Shank—Lock these bits directly into power tools. They won't wobble as much as bits paired with an adapter, so they are the best choice for high-precision tasks.

    Turn stainless steel square screws in areas exposed to moisture and chemicals. With solid stainless steel construction, these bits resist rusting and have no coating that could flake off and damage the screw drive. Well suited for woodworking tasks, they generate just enough force to drive screws into tough materials without risking cracks or splits. Also known as Robertson bits.

    These sets include an adjustable torque driver, bits for different drive styles, and a socket adapter. To adjust torque, remove the black vinyl end cap and turn the attached adjustment key. When set torque is reached, the driver slips to disengage and stop turning the fastener, preventing overtightening. Sets come with a calibration certificate that states the product has passed a test for accuracy.
    Note: Accuracy ratings do not apply to the lower 20% of the torque range.

    Torx

    Bits have a different tip at each end and snap into the shaft. A ball detent holds the bit in place. To use as nutdriver, remove the bit and turn fasteners with the shaft, which is also reversible.
    Ultra Grip—Ultra-grip drivers have a multicomponent handle that provides comfort and the best possible grip for achieving maximum torque.
    Cushion Grip—Cushion-grip drivers offer comfort and some slip resistance. Bits turn eight screw sizes and the shaft three external hex sizes.
    Voltage Detector—Those with a voltage detector safely test for AC voltage without contacting live wires. Light and sound indicators alert you when over 50 volts AC is detected. The detector is attached to the tool’s handle; remove it from the handle to use it on its own. Bits turn eight screw sizes and the shaft two external hex sizes.

    If you accidentally touch a live circuit, these bit screwdrivers prevent a dangerous zap. An insulated handle and shaft absorb up to 1,000 volts of electric shock to meet EN and IEC standards. Use these screwdrivers for everything from installing electrical panels to repairing outlets, switches, and light fixtures. Change the bit to drive a variety of screws with a single tool.
    Ultra Grip—Designed for maximum comfort and control. The soft plastic coating and contoured shape reduce strain to prevent cramping and soreness during repetitive tasks. They also guarantee a secure grip.
