Class 8 Hex Nuts are high-strength metric fasteners designed for use with compatible coarse-thread bolts and set screws. Manufactured to AS 1112.1, the range covers M6, M8, M10 and M12 sizes, with each nut featuring the standard coarse thread pitch for its nominal diameter. Class 8 mechanical properties make these nuts suitable for demanding construction, fabrication, machinery and equipment-assembly applications when selected in accordance with the governing joint design.
The hot-dip galvanised finish complies with AS/NZS 1214 and has a typical coating thickness of 50 micrometres, providing high corrosion resistance for long-term outdoor applications. The range is normally selected for use with compatible property class 8.8 bolts, subject to the relevant connection standard and engineering requirements. Each size uses a standard metric spanner or socket, supporting straightforward installation and maintenance in structural and general industrial assemblies.
