Types of SAE Flat Washers We Offer

SAE Flat Washer Plain

Plain SAE flat washers provide a basic, uncoated option for spreading load and reducing surface wear under bolts and nuts. They are commonly used in indoor or covered applications where corrosion resistance is not a major concern. Contractors and maintenance crews use plain washers for assembly and repair work where strength and simplicity are sufficient. Their cost efficiency and consistent performance make them a practical choice for everyday fastening tasks.

SAE Flat Washer Zinc Clear Cr+3

Zinc clear Cr+3 SAE flat washers feature a bright, smooth finish that offers protection against rust and wear. This finish extends the life of fastened joints while maintaining a clean appearance. They are frequently used in light commercial and industrial applications where reliability and presentation both matter. Installers prefer them for projects that require a durable yet economical washer.

SAE Flat Washer Zinc Yellow Cr+6

Zinc yellow Cr+6 SAE flat washers provide stronger corrosion resistance than clear zinc while also offering a distinctive golden finish. This coating adds longevity to the washer and allows for easy identification on the job site. They are widely chosen for construction and mechanical applications that demand longer service life. Contractors rely on them when both durability and visibility are important.

SAE Flat Washer HDG

Hot-dip galvanized SAE flat washers are coated with a thick layer of zinc for maximum corrosion resistance. They are engineered for outdoor use and structural applications exposed to weather, moisture, or harsh job site conditions. Builders use HDG washers in bridges, infrastructure, and heavy-duty projects where long-term reliability is critical. Their rugged build ensures secure connections even under challenging environments.

SAE Washers (Flat) - Material Options

South Coast Fasteners stocks SAE flat washers in materials that balance cost, strength, and durability for a wide range of precision applications.

Steel

Steel SAE washers offer strength and toughness for demanding mechanical and industrial assemblies. They are used in automotive work, heavy machinery, and construction equipment where fasteners must remain secure under vibration, torque, and constant load. Steel provides the durability needed to keep high-performance applications running reliably.

Low Carbon Steel

Low carbon steel SAE washers provide dependable performance for everyday fastening at a cost-effective price. Easier to machine and install than higher-grade alloys, they are a popular option for light-to-medium duty applications such as equipment assembly, maintenance work, and fabrication. Contractors and manufacturers choose low carbon steel when they need reliable washers without the added expense of premium materials.

SAE Washers (Flat) - Available Finishes

South Coast Fasteners offers SAE flat washers in finishes that extend their service life, resist corrosion, and match the requirements of different environments.

Hot Dip Galvanized

Hot dip galvanized SAE washers are coated in a thick layer of zinc for maximum corrosion protection. They are designed for outdoor and harsh environments, making them a trusted choice in construction, infrastructure, and marine work where moisture and weather exposure are constant.

Plain

Plain SAE washers are supplied without coatings, leaving the natural steel surface exposed. They are commonly used in controlled indoor environments, welding projects, or restoration work where uncoated hardware is needed. Plain washers are also useful in applications where parts will be painted or plated after installation.

Zinc Cr+3

Zinc Cr+3 plating gives SAE washers a clean, polished appearance along with dependable corrosion resistance. This finish is widely used in automotive, machinery, and consumer applications where washers remain visible and must retain both function and appearance. It is a versatile, cost-effective option that balances strength and protection.
