Heavy-Duty Galvanized Washers for Outdoor and Construction Applications
3/8 in. Heavy-Duty Flat Washers, Galvanized - Choose Your Quantity
These 3/8 in. heavy-duty flat washers are made from hot-dip galvanized steel for dependable performance in demanding fastening applications. Hot-dip galvanizing provides a durable protective coating that helps resist corrosion, making these washers well suited for use with pressure-treated lumber in inland construction projects and applications around freshwater.
Flat washers help distribute the clamping load of a nut or bolt over a larger surface area. This helps reduce the possibility of the fastener pulling into or damaging the material while providing a solid bearing surface for heavy-duty connections. The generous outside diameter of these washers makes them particularly useful when a larger load-distribution area is desired.
Hot-Dip Galvanized for Corrosion Resistance
Hot-dip galvanized steel has long been used for heavy-duty construction and woodworking applications where additional corrosion protection is needed. These washers are a practical choice for outdoor projects, structural assemblies, decks, and other applications where galvanized hardware is appropriate. The galvanized coating can also result in slightly looser threaded connections than stainless-steel hardware because of the variability introduced during the galvanizing process.

Ideal for Heavy-Duty Construction
Use these galvanized flat washers with compatible galvanized bolts, lag screws, and other fasteners to create strong, durable connections. They are especially useful for woodworking, outdoor construction, pressure-treated lumber, structural assemblies, and general repair and maintenance projects where a heavy-duty washer is required.
Our hot-dip galvanized fasteners have a minimum tensile strength of 60,000 psi and conform to applicable ANSI/ASME specifications for the corresponding fastener types, including ANSI/ASME B18.5 for carriage bolts and ANSI/ASME B18.2.1 for lag screws and hex-head cap screws.
Important Fastener Compatibility Information
Do not mix galvanized and stainless-steel hardware. Combining dissimilar metals can promote galvanic corrosion, potentially reducing the service life of the fasteners and connection. For best results, use compatible materials throughout the fastening assembly. Always check local building codes and project requirements for approved fastener types before construction.
