Form A Flat Washers with 8 mm inner diameter are general-purpose, round, flat washers used to spread the load under a nut or bolt head and protect the mating surface. Made from steel with a zinc-plated finish for corrosion resistance, they are suitable for use across construction, agricultural and garden machinery, and workshop fixings.

Commonly paired with M8 bolts, set screws and threaded rods, they help reduce surface damage, minimise embedment, and improve joint durability in frames, brackets, guards, covers and general fabrications.
