M6 x 90mm Roofing Bolt

A roofing bolt with a large domed mushroom head for fixing corrugated roofing sheets, metal cladding and guttering to timber purlins and frames. The oversized head spreads the clamping load across a greater area than a standard bolt, reducing the risk of the sheet material deforming or tearing around the hole.

The M6 x 90mm zinc plated version suits standard corrugated sheet assemblies where a medium-length bolt is needed. Use with an M6 nut and flat washer, or with an EPDM sealing washer where a weathertight fixing at the sheet surface is required. Common applications include corrugated steel and GRP roofing sheets on outbuildings, lean-tos and agricultural buildings.
