Mild steel fasteners are widely used for all general purposes where high strength and corrosion resistance is not required. Their low cost makes them ideal for everyday use. Mild steel Bolts and Screws conform to grades 4.6 and 4.8 and Nuts to grade 4. Higher grades of 5.6 and 5 are also arranged against order.

 

Finishes: Self colour, Zinc plated (with White/Blue/Yellow passivation), Hot Dip galvanised, Cadmium Plated, Blackened, Nickle plated and Chromium Plated.
