Description
Overview:
The M10 Form A Zinc Plated Flat Washer is a plain, flat steel washer used with M10 bolts and set screws to spread clamping force and protect the mating surface. It is manufactured to the Form A pattern and conforms to DIN 125, giving a consistent, reliable fit for standard metric fasteners. Made from carbon steel with a bright zinc-plated finish, it offers good resistance to rust in general indoor and sheltered outdoor environments. The smooth faces help prevent galling and fretting under the bolt head or nut, improving joint durability. Sold individually, it is a practical choice for workshop spares, site repairs, machinery maintenance, and DIY. Useful across construction fixings, vehicle bodies, garden machinery, plant, and equipment assembly. MPN for identification: 321 0840 500PK.
