Heavy-duty zinc-plated self-drilling screws for metal-to-metal fixings. No pre-drilling needed – up to 12mm thickness.
The Timco Heavy-Duty Hex Self-Drilling Screws are engineered for robust metal-to-metal fixings without requiring pre-drilling, making them ideal for attaching materials to heavy section steel (up to 12mm thick). These screws feature a high-quality zinc finish for excellent corrosion resistance, ensuring long-lasting performance even in demanding environments.
Constructed from case & core hardened carbon steel, these screws provide exceptional strength and durability. The No.5 self-drilling point eliminates the need for pilot holes, saving both time and effort during installation. The hex head design with an integrated fixed washer (12mm diameter) offers superior torque transmission and prevents the screw from sinking into the material, ensuring a secure and tight fit.
