M16x240 Bolt/Nut Galv
x2 M16x50x50x3 Galv Washers are supplied as standard, made with high quality 5.8 Grade Galvanized steel.
The Hex Head and Hex Nut combination make the most effective way to tighten bolts and nuts quickly, with the steel being galvanized means there is higher tensile strength and more resistant to corrosion especially for out door use including costal areas.
