    Hex Shank

    Have a range of bits ready to turn the most common screw styles and sizes.
    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).
    Steel—Best for dry environments, since moisture will cause these bits to rust.

    Drilled Spanner Bits

    Use these bits to turn drilled-spanner screws. With two thin contact points, they can't deliver a lot of torque, so they may slip if you use too much force. Also known as pig-nose 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.
