TEK Self-Drilling Screws - #10 x 1" - Self-Tapping - 500/Pkg

Self-drilling TEK screws eliminate pilot hole requirements for faster HVAC installations and metal fabrication work. Steel construction with zinc-plated coating provides superior corrosion resistance and smooth threading performance in demanding environments. Square drive design ensures secure bit engagement and reduces cam-out while pan head profile sits flush against ductwork surfaces. Self-tapping threads cut cleanly through metal without cracking or distortion, maintaining structural integrity. Engineered specifically for ventilation duct connections and metal fabrication applications where installation efficiency and long-term reliability matter most in professional settings.
