    Tamper-Resistant Torx Stainless Steel Rounded Head Screws for Sheet Metal

    Image of Product. Front orientation. Contains MultipleImages. Tapping Screws. Tamper-Resistant Torx Stainless Steel Rounded Head Screws for Sheet Metal.
    Prevent unauthorized access with screws that require a tamper-resistant Torx driver to remove. The deep, six-lobe recess (also known as pin-in-Torx) handles high torque to keep drivers from slipping and stripping the drive. These screws have a pointed tip that starts a hole in sheet metal up to 0.025" thick, but for thicker material you’ll need to drill first. Screws resist rust and have a rounded head to create a finished look.
    Length is measured from under the head.
    18-8 Stainless Steel—The choice for wet and outdoor environments, these screws resist rust. However, they won't hold up to the harsh chemicals that 316 stainless steel can.
    Power Tools Bits—Pair with your power tools to turn screws more quickly than manual tools.
