Select a product to estimate shipping.These Square Washers are designed with an enlarged outer surface area to provide superior load distribution compared to standard round washers. The wide square profile helps spread clamping force evenly across thin or soft materials, reducing the risk of pull-through, surface damage, or material deformation.
Ideal for use in construction, framing, woodworking, and structural fastening applications, square plate washers are especially effective when securing bolts or screws through wood panels, brackets, and structural connections where additional surface support is required.
Manufactured from durable zinc-plated steel, these washers offer dependable strength, abrasion resistance, and enhanced corrosion protection. The galvanized coating helps resist rust and wear, making them suitable for indoor use and light exterior environments.
