Form B flat washers manufactured to BS 4320 and DIN 125 standards are designed to provide effective load distribution and improved joint stability in professional and industrial fastening applications. Produced from high-quality steel and finished with a zinc plated coating, these washers offer good resistance to corrosion, making them suitable for indoor use and sheltered external environments. The Form B washer profile features a larger outer diameter than standard Form A washers, increasing the bearing surface beneath bolt heads and nuts to help spread clamping force more evenly. This reduces stress on fasteners and mating materials, helping to prevent surface damage and improve the integrity of bolted joints. Precision manufactured to consistent dimensions, zinc plated Form B flat washers ensure reliable compatibility with metric fasteners across a wide range of assemblies. Commonly used in construction, engineering, industrial machinery and general fabrication, these washers deliver durability, consistent performance and long service life where dependable load distribution and secure fastening are essential.
