Square Washer for Load Distribution and Structural Fastening
A square washer is a flat, square-shaped metal plate engineered to distribute load more evenly when used with bolts, screws, and threaded rods. Its larger bearing surface provides enhanced stability, making it suitable for heavy-duty fastening in construction, structural steelwork, machinery, and timber connections. Compared with standard round washers, square washers reduce the risk of pull-through and improve alignment across various materials.
Durable Construction for Professional Applications
Our square washers are manufactured from high-quality carbon steel, stainless steel, and brass. They are available with multiple surface treatments including plain finish, zinc plating, and hot-dip galvanizing. These finishes help resist rust and extend performance in both indoor and outdoor environments. Because every project has unique requirements, we support OEM customization for inner diameter, outer size, thickness, stamping design, and branding.
Easy Installation and Wide Compatibility
Installation is straightforward. Simply pair the washer with bolts, screws, anchors, or threaded rods to enhance clamping force across soft or uneven surfaces. The broad contact area provides uniform load distribution, which helps prevent deformation and improves long-term structural reliability. Consequently, square washers are widely used in wood framing, steel columns, concrete anchoring, furniture assembly, and general industrial machinery.
Applications and Internal References
Square washers are versatile components in building construction and fabrication industries. They are especially effective in large-scale projects where stability and durability are essential.
