Sirius Bolts High Tensile 8.8 Galvanised

The Sirius Bolts High Tensile 8.8 Galvanised are heavy-duty structural fasteners designed to deliver outstanding strength, durability and corrosion resistance for demanding construction and engineering applications. Manufactured from Grade 8.8 high tensile steel with a hot-dip galvanised finish, these hexagon head bolts offer superior rust protection compared to bright zinc plated alternatives — making them ideal for outdoor and exposed environments.

Suitable for structural steelwork, timber construction, fencing, agricultural equipment and infrastructure projects, these bolts feature a partially threaded shank for excellent clamping force and precision metric threads for secure fastening. The standard hexagon head allows quick installation with conventional spanners or sockets. Available in sizes M12 to M30 across a range of lengths from 45mm to 200mm.
