Grade A4-80 Stainless Steel Nut
This Stainless Steel M8 Nyloc nut is the same nut supplied in our Sign Fixing kits. It is made from A4-80 stainless steel (Type 316 for superior resistance to salinity), ensuring it has long-lasting resistance against corrosion when exposed to the elements - perfect for sign fixing. This is the same grade of stainless steel used on highways and in coastal areas.
A4 stainless is even more resistant to salinity and corrosion than type A2 stainless, so this nut offers some of the best environmental resistances available commercially.
