Roofing Bolt - M8 x 30mm

A roofing bolt has a low-profile domed or mushroom head rather than a hex head, which means less protrusion above the surface on visible or weathered faces. This makes it a popular choice for fixing corrugated or profiled steel and polycarbonate roofing sheets to purlins and structural steel, where a prominent hex head would look untidy or catch on waterproof covers. It is also used for light steelwork brackets and cladding fixings.

The M8 x 30mm size suits typical roofing sheet to purlin fixing depth and standard bracket applications. Use with a suitable M8 nut and washer — a large flat washer on the sheet side helps prevent pull-through on softer or thinner sheet materials.
