Hillman 25 Pcs Galvanized Flat Washers (5/8") | USS Steel Washers for Bolts, Nuts & Screws | Rust-Resistant Fastening Hardware for Wood, Metal, Construction & Outdoor Projects

Product Description Hillman 5/8-inch galvanized USS flat washers are designed to provide reliable support for bolts and screws in heavy-duty fastening applications. These washers help distribute the clamping force of the fastener across a larger surface area, reducing the risk of material damage while improving the strength and stability of the connection. Manufactured to USS (United States Standard) sizing specifications, these washers are designed for use with 5/8-inch bolts and screws, making them suitable for construction projects, mechanical assemblies, equipment installations, and general hardware repairs. Flat washers are an important component of a complete fastening system. By increasing the load-bearing surface beneath the fastener head, they help prevent bolts and screws from pulling through softer materials and help maintain a more secure mechanical connection. Each washer is constructed from durable steel and coated with a galvanized finish that offers excellent protection against rust and corrosion. This makes them suitable for exterior construction, deck building, structural installations, and other applications exposed to moisture or weather. Packaged in a convenient C-Pak containing 25 washers, these fasteners are ideal for contractors, builders, mechanics, and DIY homeowners working on structural projects, equipment installations, automotive repairs, and general fastening applications requiring strong and corrosion-resistant hardware. From the Manufacturer 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.
