These bits fit around the security pin to turn tamper-resistant Torx screws. Use them to unlock electronic enclosures and other access-controlled equipment. Their six lobes withstand high pressure without slipping and stripping the drive. Also known as pin-in-Torx bits.
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.
