Description
Overview:
These Form A Stainless Steel Washers are heavy-duty flat washers with a 16 mm inner diameter (approximately 0.63 inches). Made from corrosion-resistant stainless steel, they provide a stable bearing surface under bolt heads and nuts to spread the load, reduce wear, and protect components. The Form A pattern offers a tidy, flat profile suitable for general assembly across construction, agricultural, and garden machinery. Supplied in a pack of 50, they are ideal for workshop stock and site work where consistent, reliable fastening is needed. Suitable for use with fixings and shafts that require a 16 mm clearance, they help prevent surface damage on softer materials and maintain joint integrity in outdoor or damp conditions.
