Description

Streamline your metal-to-metal and metal-to-wood fastening with the industrial precision of TOKOMA Hexagonal Screws. These high-performance self-drilling fasteners eliminate the need for pre-drilling, allowing you to drill, tap, and fasten in one seamless motion. They are the professional standard for roofing, cladding, and HVAC installations.

Integrated Self-Drilling Tip: Features a precision-engineered “TEK” drill point that cuts through light-to-medium gauge steel effortlessly, significantly reducing installation time and tool wear.

High-Torque Hex Head: The robust hexagonal head design provides a positive, non-slip engagement with nut setters, allowing for maximum torque delivery without the risk of cam-out or head stripping.

Integrated EPDM Washer: Includes a pre-fitted bonded washer that creates a high-pressure, weather-tight seal upon compression, making these screws essential for leak-proof outdoor roofing and siding applications.

Optimal 30mm Length: The 4.8 x 30mm sizing provides the ideal balance of penetration and grip for securing metal sheets to timber purlins or thin-walled steel frames.

Hardened Carbon Steel: Forged from high-quality carbon steel and heat-treated for superior shear strength and structural integrity under heavy loads.

Corrosion-Resistant Coating: Finished with a protective galvanized layer to provide long-term resistance against rust and environmental weathering, ensuring a durable hold in all climates.

Drill. Fasten. Seal. The ultimate high-efficiency solution for professional metal construction.
