TechFast TFHS6322 Roofing Screw 6.3 x 22mm Pack 100

The ForgeFix TechFast Hex Head Stitching Screws are designed to join cladding sheets and roofing panels. They feature a hex head and a self-drilling point to enable quick, sheet-to-sheet fastening. A rubber washer beneath the aluminium flange expands under pressure to form a permanent weather seal, helping to prevent moisture ingress. The screws are treated with a corrosion-resistant Elementech coating to withstand outdoor conditions, including aggressive weathering. They are suitable for anchoring overlapping corrugated steel cladding, profiled metal sheet edges, flashing trim, and box profiles, and they can join up to three sheets of 0.7 mm thickness. These properties make them a trade-grade option for reliable, durable roofing applications.

• Self-drilling point enables fast sheet-to-sheet joining
