Our strongest hex-drive screws for deterring unauthorized access. Also known as pin-in-hex and pin-in-socket drives, these screws have a security pin in the drive that you can only turn with a tamper-resistant hex driver. The deep six-point opening helps them withstand torque without damaging the drive. Made of alloy steel, they have nearly twice the tensile strength of other screws. The button head looks similar to a pan head, but it's lower and more compact, taking up less space.

Length is measured from under the head.

L-Keys—Turn screws by hand for more control and less chance of overtightening compared to power tools.

Power Tool Bits—Pair these bits with your power tools to turn screws more quickly than manual tools.
