Torx Tamper-Resistant Self-Drilling Screws

Torx Tamper-Resistant Self-Drilling-Screws eliminate separate drilling and tapping operations for faster, more economical installations. Our self drilling screws provide a sharp, clean and consistent drill point, excellent thread engagement and holding power. The Torx Tamper-Resistant Drive System is recognized as one of the most efficient fastening systems available, because of its ability to transfer greater torque, reduce end load and virtually eliminate tool slippage. The fastener is extremely difficult to remove without a special tamper-resistant Torx Drive tool.
