Heavy-Duty Galvanized Washers for Outdoor and Construction Applications
5/16 in. Heavy-Duty Flat Washers, Galvanized - Choose Your Quantity
These 5/16 in. heavy-duty flat washers feature a hot-dip galvanized steel finish for dependable corrosion resistance in demanding fastening applications. Designed for use with 5/16 in. bolts, lag screws, and other compatible fasteners, these washers help distribute the load of a fastener over a larger surface area while protecting the workpiece from localized pressure.
Hot-dip galvanized flat washers have long been a standard choice for heavy-duty construction and woodworking applications. They are particularly well suited for projects using pressure-treated lumber in inland environments or around freshwater where additional corrosion resistance is needed. The galvanized coating provides durable protection while maintaining the strength and utility needed for structural fastening applications.
Heavy-Duty Construction
These washers are made from hot-dipped galvanized steel and are designed for use with heavy-duty threaded connections. The galvanizing process can result in slightly less clearance than stainless steel fasteners, so the threaded connection may have a somewhat looser fit to accommodate normal variations in the galvanized coating.

Ideal for Construction and Woodworking
Use these galvanized flat washers when you need to distribute clamping pressure and provide a durable bearing surface beneath a nut or fastener head. They are a practical choice for decks, outdoor woodworking, structural assemblies, repairs, and other projects where galvanized hardware is appropriate.
Always check local building codes and project requirements to ensure the selected fasteners meet applicable specifications before beginning construction.
Important Corrosion Consideration
Do not mix galvanized and stainless steel fasteners or other dissimilar metals. Contact between dissimilar metals can promote galvanic corrosion, potentially reducing the service life of the fastening system. Select compatible fastener materials and finishes for your specific application and environment.
