Types of F436 Structural Flat Washers We Offer

F436 Structural Flat Washer Plain

Plain F436 structural flat washers are designed to spread the load of heavy structural bolts and protect surfaces from damage. Without coatings, they are best suited for indoor or covered applications where exposure to moisture is minimal. Contractors often use them in steel-to-steel connections where strength and precision matter more than corrosion resistance. Their straightforward design makes them a cost-effective and dependable option for many structural projects.

F436 Structural Flat Washer Zinc Yellow Cr+6

Zinc yellow Cr+6 F436 structural flat washers provide superior corrosion protection compared to plain or clear zinc washers. The yellow finish also makes them highly visible on job sites, allowing for quick identification during installation. They are commonly specified in construction projects that require both strength and added durability against the elements. Builders appreciate their long service life and ease of inspection in the field.

F436 Structural Flat Washer HDG

Hot-dip galvanized F436 structural flat washers are coated with a thick layer of zinc that provides maximum corrosion resistance. They are made for outdoor and exposed structural applications such as bridges, towers, and infrastructure projects. The HDG finish ensures washers remain durable even under harsh weather and moisture conditions. Contractors rely on them for their ability to maintain secure connections in heavy-duty structural assemblies over the long term.

USA F436 Structural Flat Washer Plain

Plain USA F436 structural flat washers serve the same purpose as the standard version but are domestically manufactured to meet USA standards. They distribute loads evenly under structural bolts and provide surface protection where coatings are not required. These washers are typically used indoors or in controlled environments where corrosion is not a factor. Contractors choose USA-made plain washers for projects requiring domestically sourced components.

USA F436 Structural Flat Washer Zinc Cr+3

USA F436 structural flat washers with a zinc Cr+3 finish combine strength with moderate corrosion resistance. The coating helps prevent rust while keeping a clean, bright appearance. They are widely used in commercial and industrial projects where durability and professional presentation are both important. Builders rely on them for a balance of performance, cost efficiency, and compliance with domestic sourcing requirements.

F-436 Washers (Structural) - Material Options

South Coast Fasteners stocks F-436 washers in medium carbon steel that has been heat-treated to provide the hardness, toughness, and strength needed for structural connections under heavy loads.

Medium Carbon Steel

Medium carbon steel gives F-436 washers the durability they’re known for. Heat treatment adds extra hardness, allowing these washers to hold up against crushing forces while maintaining their shape. They are commonly paired with structural bolts in high-load applications like steel framing, highway construction, and bridgework where reliability cannot be compromised.

F-436 Washers (Structural) - Available Finishes

South Coast Fasteners offers F-436 washers in finishes that deliver corrosion protection, durability, and the right appearance for both indoor and outdoor builds.

Hot Dip Galvanized

Hot dip galvanized F-436 washers carry a thick zinc coating that protects the steel from rust in outdoor and weather-exposed conditions. This finish is ideal for bridges, utility work, and structural framing where long-term durability in harsh environments is required.

Plain

Plain finish washers provide an untreated steel surface that is weld-friendly and easy to coat or paint after installation. They are a practical choice for indoor projects, shop fabrication, or controlled environments where corrosion isn’t a major concern.

Yellow Zinc Cr+6

Yellow zinc Cr+6 offers a golden chromate layer that improves corrosion resistance while making washers easy to spot during installation and inspection. This finish is commonly used in mechanical or industrial settings where visibility and reliability both matter.

Zinc Cr+3

Zinc Cr+3 provides a clean, bright finish with basic corrosion protection in a trivalent formula that meets modern environmental standards. It is widely used across construction and fabrication projects where a neat, professional look is paired with dependable protection.
