Watertight Fixings for Deeper Steel Profiles & Layered Trims

These 25mm x 5.5mm hex head self drilling screws with EPDM washers are ideal for fastening steel cladding, flashings, and profiles into light gauge metal up to 5mm thick — no pre-drilling required. The added length (compared to the 19mm version) offers better engagement in layered assemblies or thicker steelwork.

Each screw comes pre-assembled with a 16mm EPDM bonded washer that compresses under torque to create a weather-resistant seal, making them perfect for external use. The hex washer head offers strong clamping force, and the BZP (Bright Zinc Plated) finish delivers corrosion resistance and a clean appearance.

Popular applications include: roofing sheets, overlap joints, flashings, trims, wall panels, and signage brackets exposed to weather.
