Sheet to Timber Tek Screws are specifically designed to securely anchor corrugated metal panels to wooden purlins and battens, ensuring long-term, weather-resistant roof performance. Perfect for a range of projects—from replacing a leaking garden shed roof in a rainy Sussex winter to constructing a stable or livestock shelter on a rural farm, or adding a durable canopy over a driveway extension—these screws deliver rock-solid grip without compromising timber integrity.
With fast installation and exceptional hold in both softwood and hardwood frameworks, these screws are stocked in boxes of 100 and available in multiple lengths to suit various timber depths. Designed to withstand the elements, they ensure your corrugated roofing remains strong against wind, rain, and seasonal changes for decades.
Key features
- Superior Timber Grip for Wind-Resistant Roofs: The specialised high/low thread bites deeply into wooden purlins and battens, providing outstanding pull-out resistance—crucial for keeping corrugated sheets secure during strong UK gusts on exposed sheds, barns, or garden structures.
- Long-Lasting Rust Protection in Damp Conditions: Equipped with an advanced corrosion-resistant coating that exceeds 1,000 hours in salt-spray tests, these screws maintain integrity for 15–25+ years, ideal for humid rural farms, coastal garages, or any timber-framed roof exposed to frequent rain and condensation.
- Reliable Leak-Proof Seal on Wooden Frameworks: The generous 19mm bonded EPDM washer compresses firmly against the metal sheet and timber, creating a durable, flexible seal that prevents water tracking down screw holes—essential for avoiding rot in wooden supports on sheds, outbuildings, and agricultural shelters.
- Quick, Clean Installation Without Splitting Wood: The sharp self-drilling slash point cuts smoothly through thin metal (up to 0.8mm) and into timber in one easy step, with lower torque requirements that minimise splitting in softwoods like pine—saving time on DIY garage roofs or professional barn conversions.
- Tailored for Everyday Timber Roofing Projects: Whether you’re refreshing an old allotment shed, erecting a new timber-framed workshop, or cladding a domestic extension with corrugated panels, these screws pair perfectly with wooden purlins to deliver professional-grade, long-lasting results every time.
- Trusted Quality for Safe, Compliant Builds: Fully CE marked and compliant with BS EN ISO 10666 standards, these screws give peace of mind for both trade professionals and homeowners tackling regulated or insured roofing work on timber structures.
Sheet to timber Tek screws FAQs
What are these Tek screws ideal for?
- Corrugated, box-profile and tile-effect metal roofing.
- Fixing directly into softwood or hardwood purlins and battens.
- New builds, re-roofing projects and agricultural buildings.
What are sheet-to-timber Tek screws used for?
These screws are designed specifically for attaching sheet metal (up to 0.8mm thick) to timber. They are ideal for roofing, cladding, and other applications where metal sheets need to be securely fastened to wooden structures.
Which length is most popular?
The 6.3 × 32 mm is the top-seller by a considerable margin. It provides 20–30 mm embedment into typical 38–50 mm-deep softwood purlins when fixing 0.5–0.7 mm corrugated roofing sheets, which is precisely the right amount of thread for maximum holding power without risking splitting or poking through the underside.
What lengths are available for these screws?
Our Tek screws – sheet to timber are available in the following lengths:
- 6.3 × 25mm.
- 6.3 × 32mm.
- 6.3 × 45mm.
- 6.3 × 60mm.
- 6.3 × 80mm.
- 6.3 × 100mm.
These sizes suit a range of timber thicknesses and sheet metal types.
Can I use these for metal-to-metal applications?
No, these screws are designed explicitly for sheet metal-to-timber applications. If you need screws for connections (such as for cladding or roofing sheets), we recommend our sheet-to-sheet Tek screws.
Can I use these on steel purlins?
No, the slash point drills only up to 0.8 mm timber.
What makes these screws corrosion-resistant?
The screws feature exterior-grade plating for excellent corrosion resistance and are proven to withstand over 1,000 hours of salt spray, making them suitable for coastal or wet climates.
How do these screws reduce the risk of timber splitting?
The single slash point on the screw is designed to reduce torque, helping prevent splitting of the timber, particularly when screws are installed close to the edge. This quality allows for smoother installation and protects the wood from damage.
Are these screws for outdoor use?
Yes, these screws are engineered specifically for exterior use. Their corrosion-resistant coating and EPDM washer make them well-suited for outdoor applications, especially in challenging weather conditions.
