Form A Flat Washers with a 5 mm inner diameter are general-purpose washers used to spread the load of a bolt, set screw, or stud and protect the contact surface.

Suitable for M5 fasteners, these washers are widely used across construction, plant, and garden machinery, from engine mounts and brackets to guards and panels. Supplied in a bulk pack of 1000 pieces for workshops and site kits. Manufacturer Part Number (MPN): 903 0837.
