About Roofing & Cladding Screws
Roofing and cladding screws are engineered for fixing cladding panels, roofing sheets and associated window and door flashings to structural steel, timber and composite substrates. Self-drilling tips eliminate the need for pre-drilling in most applications, significantly reducing installation time.
Glazing Supplies Direct stocks TechFast and equivalent self-drilling cladding screws in hex washer head and countersunk profiles. All screws are CE approved and available in trade packs for building contractors and window and door installation companies.
Frequently Asked Questions
What is a self-drilling cladding screw?
A self-drilling screw (also called a "tek screw") has a drill-point tip that cuts through the substrate without a pre-drilled hole, making installation faster on steel and composite structures.
Are TechFast screws suitable for steel cladding?
Yes — TechFast self-drilling screws are designed to fix through cladding panels directly into light-gauge steel purlins and rails. Check the point number (e.g. Point 3 or Point 5) for compatibility with the steel thickness.
