With larger lobes than Torx bits, these deliver even more torque without slipping and stripping the drive. They have a similar profile to Torx but are not recommended for use with standard Torx screws.
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.
