Square Washer

Square Washers are flat washers with a square outer profile, providing a greater bearing surface than standard round washers. They are commonly used in timber construction, channel sections, and structural bolting applications. Manufactured to ASTM and DIN standards, they are available in multiple materials, sizes, and coatings. Their wide surface area prevents bolt heads and nuts from embedding into softer materials like wood. They are widely used in construction, railways, power transmission, and heavy structural assemblies.
