The Flange Hexagonal Nuts are A2 Grade Stainless Steel and meets DIN 6923 Specification.
The Nut has a wide flange at one end that acts as an integrated, non-spinning washer. This serves to distribute the pressure of the nut over the part being secured, reducing the chance of damage to the part and making it less likely to loosen as a result of an uneven fastening surface.
A2 Grade (Also known as 304) means that they are 30% stronger than ordinary carbon steel, corrosion resistant, and retains its strength at high temperature - All of which means it will last longer!
These stainless steel nuts will fit a Metric Screw threaded Bolt, hex nut or threaded rod.
These nuts are ideal for both indoor and outdoor use, as stainless steel does not rust from water exposure.
Perfect for a wide range of DIY tasks.
