Hexagonal Screws (4.8×50mm)

Description

Achieve maximum reach and structural security with the TOKOMA Extra-Long Hexagonal Screws. These professional-grade self-drilling fasteners are engineered to penetrate, tap, and lock in one efficient operation, eliminating the need for pilot holes. With an extended 50mm length, they are the ideal choice for securing thick metal sheeting, insulation panels, or heavy-duty cladding to timber and steel substructures.

Industrial Self-Drilling “TEK” Point: Features a high-performance drill tip that cuts through metal sheets and light structural steel with ease, drastically reducing installation time on large-scale projects.

Extended 50mm Reach: The substantial 4.8 x 50mm profile provides the necessary depth for fastening through insulation layers or securing thick timber members to metal frames.

High-Torque Hex Head Design: The oversized hexagonal head ensures a rock-solid connection with nut setters, allowing for high-pressure driving without the risk of slipping or damaging the fastener head.

Weather-Tight EPDM Seal: Equipped with a pre-assembled bonded washer that compresses upon installation to create a permanent, leak-proof barrier—essential for roofing and exterior wall applications.

Superior Shear Strength: Forged from high-tensile carbon steel and professionally heat-treated to withstand extreme structural loads and environmental stresses.

Galvanized Corrosion Protection: Finished with a premium anti-corrosive coating to prevent rust and degradation, ensuring a long-lasting, reliable hold in exposed outdoor environments.

Extended reach. Weather-proof sealing. Industrial-grade efficiency for heavy-duty construction.
