Description
Overview:
These Form A flat washers are general-purpose load-spreading washers made from zinc‐plated steel and supplied in a bulk pack of 250. With a 12 mm inner diameter (ID), they are suited to M12 bolts and studs, helping to distribute clamping force and protect mating surfaces from damage. The Form A pattern offers a standard outside diameter with a smooth, flat bearing face for consistent tightening. The bright zinc plating provides everyday corrosion resistance for both indoor and outdoor use on construction equipment, garden machinery, fixtures, and assemblies. Use them under bolt heads or nuts to reduce embedment, prevent pull-through, and maintain clamp load. Manufacturer Part Number: 903 0841. A practical choice for workshops, site kits, and maintenance teams.
