Material Options

South Coast Fasteners stocks stainless steel washers in a range of materials that balance strength, cost, and corrosion resistance for different applications.

Stainless Steel 304

Stainless 304 is the go-to material for general-purpose washers. It resists rust in most everyday environments, making it suitable for construction, light industrial use, and equipment assembly. Contractors rely on 304 when they want dependable corrosion resistance without paying for the higher grades needed in harsher conditions.

Stainless Steel 316

Stainless 316 is the top choice for coastal, marine, and chemical environments. Its superior resistance to salt, moisture, and aggressive chemicals makes it the washer material for docks, pipelines, and processing facilities. When failure isn’t an option, 316 gives long-term protection.

Stainless Steel 18-8

Stainless 18-8 is versatile and cost-effective. It offers solid strength, dependable corrosion resistance, and affordability, making it one of the most widely used stainless grades. Found in construction, mechanical work, and general assembly, 18-8 is often the default choice when budgets matter but rust resistance is still required.

Bonded Neoprene and Stainless

Bonded neoprene washers combine a stainless steel body with a neoprene backing. This design seals against liquid, air, and dust, making them perfect for watertight or airtight applications. They’re widely used in roofing, HVAC, plumbing, and anywhere leak prevention is just as important as fastening strength.

Available Styles

South Coast Fasteners offers stainless steel washers in styles that support everything from basic load distribution to highly specialized engineering requirements.

Standard Flat Washers (Stainless)

Flat stainless washers are designed for everyday load distribution under nuts and bolt heads. They spread pressure evenly and protect surfaces from wear, keeping fasteners stable in general-purpose construction and assembly.

Fender Washers (Stainless)

Fender washers feature a larger outer diameter, providing extra surface area and support. They are commonly used when fastening into softer materials like wood, sheet metal, or plastic, helping to prevent pull-through and damage.

AN960 Washers (Stainless)

AN960 washers are aviation-grade, precision washers with uniform thickness and tight tolerances. They are specified in aerospace and defense work where consistency and reliability are mandatory.

MS15795 Washers (Stainless)

MS15795 washers are military-spec components built for strength and precision. They are engineered to maintain performance in demanding assemblies where failure is not an option.

NAS620 Washers (Stainless)

NAS620 washers are aerospace-grade, offering high tensile strength and precision fit for critical high-performance applications. They are designed for use in systems where extreme reliability is required.

Bonded Sealing Washers (Stainless/Neoprene)

Bonded sealing washers combine stainless strength with neoprene flexibility to create a tight seal around bolt and screw connections. They are trusted in HVAC, roofing, plumbing, and other jobs where keeping out water, air, or dust is critical.
