    Tamper-Resistant Hex-Drive Steel Button Head Screws

    Image of Product. Front orientation. Rounded Head Screws. Tamper-Resistant Hex-Drive Steel Button Head Screws.
    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.
    Black-Oxide Alloy Steel—Typically chosen for their appearance, these screws have a dark, matte coating to create a finished look. They offer minimal corrosion resistance, so they're best for dry environments.
    Power Tool Bits—Pair these bits with your power tools to turn screws more quickly than manual tools.
