Description
Overview:
M5 Form A Flat Washers are flat, round plain washers designed to spread the load of an M5 bolt or screw head and protect mating surfaces. Made from durable steel with a bright zinc-plated finish, they offer good corrosion resistance for indoor and outdoor use on construction and garden machinery. Conforming to DIN 125 Form A, they provide consistent dimensions for predictable fitting and reliable clamping. The standard M5 Form A size has a 5.3 mm clearance hole, a 10 mm outside diameter, and approximately 1 mm thickness, giving dependable support without adding bulk. Suitable for use with M5 bolts, set screws, and machine screws in brackets, guards, housings, frames, and engine or deck assemblies. Sold individually so you can buy the exact quantity needed for maintenance, repair, and assembly tasks.
