    Tamper-Resistant Hex Bits

    These bits fit around the security pin to turn tamper-resistant hex screws. Use them to unlock electronic enclosures and other access-controlled equipment. Their six contact points deliver more torque than slotted and Phillips bits without slipping and stripping the drive. Also known as pin-in-hex or pin-in-socket 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.

    Bit Screwdrivers

    Cushion Grip

    Don't lug around a toolbox full of drivers—just swap out the bit to drive multiple screw sizes and styles with one tool. The ultimate space savers, these bit screwdrivers are a smart solution for on-the-go jobs.
    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.
    Cushion Grip—Made of soft plastic to make gripping and squeezing the handle more comfortable.
