Precision-engineered for superior clamping performance
Our Phillips Modified Truss Self-Tapping Screws combine industrial-strength threading with an optimized head design to deliver unmatched fastening reliability. Featuring a unique low-profile truss head with expanded bearing surface, these screws prevent material pull-through while maintaining flush installation. The self-tapping tip eliminates pre-drilling requirements, significantly reducing installation time across metal, wood, and composite applications.
Engineered for Maximum Efficiency
Experience next-generation fastening with our industrial-grade Phillips Modified Truss Self-Tapping Screws. The specially designed head profile provides 30% wider load distribution than standard truss heads, reducing surface deformation in thin-gauge metals (up to 14-Ga) and brittle materials. Deep-cut Phillips drive slots ensure positive bit engagement, minimizing cam-out during high-torque installations with impact drivers.
Performance Features:
✓ Modified Truss Head Design: Low-profile geometry with expanded bearing surface prevents pull-through
✓ Self-Tapping Tip: Sharp-cut threads create precise mating in steel, aluminum, and hardwoods
✓ Corrosion Defense: Zinc-plated finish (ASTM B633) or optional galvanized coating
✓ High-Torque Compatibility: Reinforced drive recess withstands 25% higher torque than standard Phillips
✓ Material Versatility: Effective in sheet metal, plastic composites, HVAC ducting, and wood framing
