The Grade 8.8 Blackened Spring Washer and Flat Washer are high-performance fasteners made from carbon steel and treated with a blackened finish for enhanced durability and corrosion resistance. These washers are designed for use in heavy-duty applications, providing reliable performance and long-lasting protection for industrial, automotive, and construction environments.
The Grade 8.8 classification ensures these washers provide high tensile strength and are capable of handling significant mechanical stress. The spring washer provides increased tension and prevents loosening of fasteners, while the flat washer ensures an even distribution of load, reducing the risk of material damage during fastening.
The blackened finish adds an extra layer of protection against rust and corrosion, making these washers ideal for use in outdoor, high-moisture, or chemically aggressive environments. Manufactured according to national standards (GB), these washers are reliable, durable, and ideal for securing mechanical components, machinery, and other applications where strength and resilience are required.
