Flat washers are commonly used with bolts, screws, and threaded rods to help distribute the clamping force across a wider surface area. By spreading the load more evenly, washers help prevent damage to the material surface, reduce the risk of fasteners pulling through softer materials, and improve overall connection stability. These washers are manufactured to USS (United States Standard) specifications and are designed for use with 5/16-inch bolts or screws, ensuring proper compatibility with standard hardware systems. Constructed from durable steel, these washers feature a galvanized coating that provides superior resistance to rust and corrosion. This corrosion protection makes them suitable for outdoor construction projects, equipment installations, and environments exposed to moisture. Galvanized washers are commonly used in construction, deck building, structural assemblies, machinery installations, fencing projects, and general hardware applications where long-lasting corrosion protection is required. Packaged in a convenient C-Pak containing 100 galvanized flat washers, these fasteners are ideal for contractors, builders, mechanics, and DIY homeowners working on construction projects, equipment installations, and general fastening tasks requiring durable hardware.
Used in applications with nuts and bolts. The flat washer provides a greater bearing surface which helps prevent a nut or bolt head from tearing through the material. Flat washers are commonly used in decks and fence building. The called out size is the inner diameter of the washer.
