Types of Round Plate Washers We Offer

Round Plate (Dock) Washer Plain

Plain round plate (dock) washers are designed with a larger outside diameter to spread load across a wider surface area. Without a coating, they are best suited for indoor or protected applications where corrosion is not a concern. Contractors use them in heavy timber construction, dock work, and structural projects where strength and stability are required. Their simple, robust design makes them an economical solution for high-load connections.

Round Plate (Dock) Washer HDG

Hot-dip galvanized round plate (dock) washers provide the same wide bearing surface with superior corrosion protection. The thick zinc coating ensures long-lasting durability even when exposed to moisture, weather, or outdoor environments. They are commonly used in marine, dock, and structural applications where washers must withstand the elements. Builders trust HDG round plate washers for secure fastening and extended service life in demanding conditions.

Material Options

South Coast Fasteners stocks round plate washers in steel, providing the strength, durability, and cost-effectiveness needed for general construction and heavy fastening.

Steel

Steel round plate washers are trusted across the construction industry for their ability to handle demanding loads. Their large diameter gives them greater surface coverage than standard flat washers, reducing stress on wood, concrete, or steel connections. From anchoring beams to securing heavy machinery, steel plate washers deliver both holding power and reliability. They are a staple in framing, foundation work, and infrastructure projects where strong, straightforward performance is required.

Available Finishes

South Coast Fasteners offers round plate washers in finishes that provide protection against corrosion, adaptability for specific environments, and the right surface for specialized applications.

Hot Dip Galvanized

Hot dip galvanized plate washers are built for rugged, outdoor environments. The thick zinc coating protects steel from corrosion caused by rain, soil, or salt exposure, making these washers ideal for bridges, marine work, landscaping, and outdoor framing. They’re the go-to finish when a washer needs to stand up to years of exposure without failing.

Plain

Plain finish plate washers provide an untreated steel surface, making them weld-friendly and easy to customize. They’re commonly used in fabrication shops, restoration projects, or indoor structural work where corrosion isn’t a concern. The plain surface also allows builders to apply custom coatings or paints after installation to match specific project requirements.
