5/16 in. Heavy-Duty Galvanized Flat Washers - Qty:25
Heavy-Duty Galvanized Washers for Outdoor and Construction Applications
5/16 in. Heavy-Duty Flat Washers, Galvanized - Qty: 25
These 5/16 in. heavy-duty flat washers are made from hot-dip galvanized steel for reliable corrosion resistance in demanding fastening applications. Galvanized flat washers are commonly used with pressure-treated lumber and other outdoor projects in inland or freshwater environments where protection against moisture and corrosion is important.
The heavy-duty design provides a broad bearing surface between the fastener and the material, helping distribute the clamping load and reduce the potential for the fastener head or nut to pull into the work surface. Hot-dip galvanizing provides a durable protective coating suitable for a wide range of construction, woodworking, and general-purpose fastening applications.
Hot-Dip Galvanized Steel
Hot-dip galvanized fasteners have been a proven choice for heavy-duty applications for many years. The galvanizing process can result in slightly looser threaded connections than stainless steel fasteners because of the variability in the galvanized coating. Our hot-dip galvanized fasteners have a minimum tensile strength of 60,000 psi and conform to applicable ANSI/ASME standards for the corresponding fastener types.

Heavy-Duty Applications
These galvanized flat washers are well suited for construction, woodworking, outdoor projects, pressure-treated lumber, and other applications requiring a durable washer with corrosion-resistant protection. They can be used with compatible galvanized bolts, lag screws, and other fasteners to help create secure, properly supported connections.
Important Fastener Compatibility
Do not mix galvanized and stainless steel fasteners or components. Combining dissimilar metals can promote galvanic corrosion, which may reduce the service life of the fastening system. Use compatible materials throughout the connection whenever possible.
Always check local building codes and project requirements to determine the appropriate fastener type and corrosion protection for your application.
