Tamper-Resistant Tri-Wing® Stainless Steel Rounded Head Screws for Sheet Metal
 |
Prevent tampering with screws that turn only with a Tri-Wing® driver. The three offset slots handle high torque to prevent slipping and damaging 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 corrosion and have a rounded head for 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.
