Flat Washer Form C - A2 (304) Grade Stainless Steel

Our Form C Flat Washers in A2 (304) Grade Stainless Steel are high-quality metric fastening components designed to provide effective load distribution and reliable support when used with compatible nuts, bolts and threaded fasteners. Manufactured from A2 (304) grade stainless steel, these washers offer excellent resistance to corrosion in many indoor and outdoor environments, making them a popular choice for engineering, fabrication, construction, maintenance and general assembly applications. Featuring the Form C large outside diameter design, these flat washers provide a wider bearing surface than standard Form A washers of the same nominal thread size. This helps distribute clamping pressure over a larger area, reducing the risk of damage to softer materials and supporting secure fastening arrangements. Available in metric sizes from M4 to M16, these stainless steel washers are suitable for a wide range of fastening applications where durability, corrosion resistance and a larger bearing surface are required. Whether used in machinery assembly, structural fabrication, stainless steel installations or general engineering work, A2 Stainless Steel Form C Washers provide a practical and dependable fastening solution.

A Form C flat washer features a larger outside diameter than a standard Form A washer of the same nominal size. This increased bearing surface helps distribute the clamping load over a wider area, making Form C washers particularly useful when fastening components where a standard washer may provide insufficient support. Common applications include securing brackets, sheet metal, fabricated components and machinery assemblies. Benefits of A2 (304) Stainless Steel A2 stainless steel, commonly associated with 304-grade stainless steel, is widely used in fastening applications because of its combination of durability and corrosion resistance. Its advantages include: Good resistance to atmospheric corrosion Suitable for many indoor and outdoor installations Durable performance in general engineering applications Attractive natural stainless steel finish Low maintenance requirements Compatibility with suitable stainless steel nuts and bolts For highly corrosive, marine or chloride-rich environments, A4 (316) stainless steel may be more appropriate. Why Choose Form C Stainless Steel Washers? The A2 (304) Stainless Steel Form C Flat Washer is an excellent choice for professional engineers, fabricators, installers and maintenance personnel requiring a corrosion-resistant washer with a larger bearing surface. With sizes available from M4 to M16, these washers provide a versatile solution for a wide range of mechanical fastening and assembly applications. Please Note: Always select the correct washer size for the bolt or threaded fastener being used. Confirm outside diameter, thickness and applicable dimensional standard where precise fitment is required. A2 stainless steel is not recommended for every marine or highly corrosive environment. Washers are supplied in the selected size and quantity.

Flat Washer Form C DIN 9021 - BZP

Metric Flat Washer Form C – Bright Zinc Plated (BZP) These Metric Flat Washers Form C are manufactured from high-quality steel and finished with a durable Bright Zinc Plated (BZP) coating, offering excellent corrosion resistance and dependable performance across a wide range of engineering, construction, fabrication, and industrial fastening applications. Form C flat washers feature a larger outside diameter than standard Form A washers, providing an increased bearing surface to distribute the clamping load over a wider area. This helps reduce the risk of damage to softer materials, prevents fasteners from pulling through oversized holes, and improves load distribution in demanding applications. Manufactured to DIN 9021 / ISO 7093-1 standards, Form C washers are ideal for use with metric bolts, setscrews, machine screws, and threaded bar where additional support is required. Their larger profile makes them particularly suitable for sheet metal, timber, plastic, and oversized clearance holes. Key Features: Manufactured from high-quality steel Bright Zinc Plated (BZP) finish for enhanced corrosion resistance Large outside diameter for increased load distribution Ideal for oversized holes and softer materials Helps prevent pull-through and surface damage Suitable for use with metric bolts, screws and threaded bar Manufactured to DIN 9021 / ISO 7093-1 specification Ideal for engineering, fabrication, automotive, construction and general industrial use Available in a wide range of metric sizes Specifications: Product Type: Metric Flat Washer Style: Form C (Large Outside Diameter) Material: Steel Finish: Bright Zinc Plated (BZP) Standard: DIN 9021 / ISO 7093-1 Internal Diameter: To suit selected metric bolt size Applications: Engineering, Fabrication, Construction, Automotive, Machinery, Timber, Sheet Metal and General Industrial Fastening

Flat Washer Form A DIN 125 - BZP

Metric Flat Washer Form A – Bright Zinc Plated (BZP) These Metric Flat Washers Form A are manufactured from high-quality steel and finished with a durable Bright Zinc Plated (BZP) coating, providing reliable corrosion resistance and long-lasting performance in a wide range of engineering, construction, automotive, and industrial fastening applications. Designed to distribute the load of a nut or bolt over a larger surface area, Form A flat washers help prevent damage to the material being fastened, reduce the risk of the fastener pulling through, and provide a smooth bearing surface for improved clamping performance.
