Turn Frearson screws, which are frequently found on marine equipment. With narrower wings than Phillips bits, these deliver more torque without slipping and damaging the screw recess. Also known as Reed and Prince bits.
One bit turns drives of all 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).
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.
