Flat Washers BS 4320 Form C (Zinc Plated) are standard flat washers designed to British Standard 4320 with a zinc-plated finish. The zinc plating provides excellent corrosion resistance, making them ideal for use in environments where protection against rust and oxidation is essential.
Form C washers have a larger outer diameter than Form A, offering greater surface area to distribute loads more effectively, reducing pressure and wear on the fastened material. These washers are commonly used with bolts, screws, and nuts to improve load distribution and prevent surface damage, especially in outdoor or moist environments where corrosion resistance is critical.
