These high-performance screws offer strength, ease of use, and long-term durability, ensuring your roofing projects can withstand the UK’s challenging weather conditions. Available in boxes of 100, they come in various lengths to accommodate different timber depths and sheet thicknesses, helping you achieve professional results every time.
Our Sheet-to-Timber Tek Screws are crafted for precision and performance. Below are the detailed specs:
Specification | Details |
Diameter | 6.3mm |
Head Type | Hexagonal head for easy driving with standard tools |
Drive Type | Compatible with hex socket drivers |
Material | High-grade steel with advanced corrosion-resistant coating |
Washer | 19mm EPDM bonded washer for superior sealing |
Drilling Capacity | Self-drilling point penetrates up to 0.8mm of steel sheet and timber in one step. |
Thread Design | High/low thread pattern for optimal pull-down force and reduced timber splitting |
Quantity | Sold in boxes of 100 screws |
Compliance | Meets BS EN ISO 10666, CE marked, and aligns with BS 2482:2009 guidelines |
Applications | Ideal for fixing corrugated, box-profile, or tile-effect metal sheets to softwood or hardwood purlins and battens. Not suitable for metal-to-metal or thick steel purlin attachments |
You can also buy sheet-to-sheet roof fixings for joining metal corrugated roofing sheets in overlaps, side laps, end laps, and other metal-to-metal connections (ideal for ridges, flashings, and secure stitching).
We offer a selection of lengths to accommodate various project requirements. The table below outlines available sizes, recommended timber embedment, and suitable applications:
| Length (mm) | Recommended Timber Embedment (mm) | Suitable Sheet Thickness (mm) | Ideal For |
|---|---|---|---|
| 25 | 10-15 | 0.5-0.7 | Shallow purlins, light-duty roofing |
| 32 | 15-25 | 0.5-0.7 | Standard sheds and garages (most popular) |
| 45 | 25-35 | 0.5-0.7 | Deeper battens, medium structures |
| 60 | 35-50 | 0.5-0.7 | Agricultural buildings, thicker timbers |
| 80 | 50-70 | 0.5-0.7 | Heavy-duty installations, large roofs |
| 100 | 70-90 | 0.5-0.7 | Extra-deep supports, industrial applications |
Note: Embedment depths are approximate and depend on timber type (e.g., softwood like pine requires less depth than hardwood). Always ensure at least 20mm penetration for secure hold.
These screws are specifically designed to attach metal roofing sheets, such as our corrugated options, directly to timber frameworks. They’re perfect for creating weatherproof roofs on outbuildings, extensions, and temporary structures.
Select a length that allows for at least 20-30mm embedment into the timber after passing through the sheet. For example, the 32mm size is ideal for standard 38-50mm deep softwood purlins with 0.5-0.7mm sheets.
Yes, their advanced coating provides excellent corrosion resistance, making them suitable for exposed, wet conditions. The EPDM washer ensures a watertight seal.
No, a standard drill with a hex bit is sufficient. The self-drilling point eliminates the need for pre-drilling in most cases.
No, these are optimised for timber. For metal-to-metal fastening, consider our alternative screw options.
Typically, 4-6 screws per square meter, depending on wind load and purlin spacing (max 1.2m apart). Consult building regulations for your project.
Our screws are made from sustainably sourced materials and are fully recyclable, aligning with eco-conscious construction practices.
The 6.3 × 32 mm screw is the best-selling option, delivering optimal holding power by providing 20–30 mm embedment in softwood purlins when fixing 0.5–0.7 mm corrugated roofing sheets, without splitting or protruding through the wood.
The single slash point lowers torque, minimizing timber splitting—especially near edges. This allows for smoother installation and preserves wood integrity.
Yes, they’re designed for exterior use, with a corrosion-resistant coating and an EPDM washer for durability.
| Size | 6.3mm × 25mm, 6.3mm × 32mm, 6.3mm × 45mm, 6.3mm × 60mm, 6.3mm × 80mm, 6.3mm × 100mm |
