Description
These self-drilling screws are engineered for fastening composite materials, PVC, and wood to metal frames in both indoor and outdoor construction. They feature a countersunk PH-type head for a flush finish and efficient torque transfer. The hardened drill tip eliminates the need for pre-drilling, while the breakaway wings enlarge the hole in the upper material to prevent lifting and ensure clean thread engagement with metal. A zinc coating provides C2-rated corrosion resistance, in accordance with LST EN ISO 12944-2:2000, making them suitable for protected outdoor environments.
Typical applications include:
Decking – Securing composite or hardwood boards to steel joists
Interior framing – Mounting battens, panels, or substructures to metal studs
Pergolas/outdoor structures – Fastening wood to galvanized or steel posts
Window and door framing – Fixing PVC or composite trims to steel frames
Vehicle flooring – Attaching plywood or panels to steel chassis (e.g., truck beds)
