Our professional carbon steel blackened washers are precision-manufactured to meet GB849 (spherical washer) and GB850 (taper washer) standards, designed for industrial fastening, mechanical assembly, and equipment maintenance scenarios. Crafted from high-quality carbon steel with a professional blackening treatment, these washers deliver excellent corrosion resistance, rust prevention, and wear resistance, ensuring stable performance in harsh industrial environments.
This product line includes four types of washers to meet diverse installation needs: spherical washers (GB849), taper washers (GB850), concave-convex washers, and bowl washers, available in M6, M8, and M10 sizes. Each washer undergoes strict quality inspection to ensure precise dimensions, smooth surfaces, and perfect compatibility with standard bolts, nuts, and mounting tools.
The blackened surface treatment not only enhances the washer’s durability and rust resistance but also provides a sleek, professional appearance, suitable for both industrial and mechanical applications. Spherical and taper washers (GB849/GB850) are ideal for adjusting alignment and reducing friction
