High Tensile Hexagon Nut

A heavy duty high tensile structural nut (deeper than standard), manufactured to Australian standard 1252 and hot dipped galvanised for maximum corrosion protection. Suitable for structural high strength bolting of steel and timber components in construction and engineering.

Zinc plating provides a moderate corrosion resistance suitable for indoors or otherwise dry conditions. Colour is either a blue-ish tint or yellow depending on the exact process utilised during manufacture.

316 Stainless Steel has increased corrosion resistance due to the addition of 2% to 3% molybdenum. It is suitable for marine, chemical, petrochemical, manufacturing and transport use.

An 'as produced' black finish on carbon steel products having an oil residue which provides some shelf life but no real corrosion protection when in use.
