Please specify the required metric thread specification (such as M6) when purchasing. Packaging methods: 2 pieces/bag, 4 pieces/bag, 10 pieces/bag, 20 pieces/bag, 40 pieces/bag, 60 pieces/bag, 100 pieces/bag, 200 pieces/bag, 400 pieces/bag, 600 pieces/bag, 1000 pieces/bag, or packaged according to customer requirements. 3、 Product materials Main material: H56 brass (copper zinc alloy), uniform material, smooth surface. Material advantages: It has good conductivity, thermal conductivity, and mechanical properties, and is not prone to sparking. 4、 Performance Excellent sealing performance: The flat and smooth surface can form an effective seal between the connecting parts, preventing liquid or gas leakage. Outstanding conductivity: As a metal gasket, it can provide a good electrical conductivity path for connecting components. Corrosion resistance: It has good corrosion resistance to water, atmosphere, and non oxidizing organic matter, with a long service life. Pressure resistance and buffering: With a certain degree of softness, it can buffer vibration, disperse pressure, and protect the surface of the connected parts. 5、 Features Standard compliance: Production strictly follows GB97 standards, with precise dimensions to ensure perfect fit with standard screws. Surface smoothness: After treatment, the surface oxidation is slight, the color is uniform, and the installation is smooth. Moderate flexibility: Moderate hardness, which can effectively seal without excessively damaging the contact surface. Long term stability: not easily magnetized, stable performance at room temperature, and not prone to aging. 6、 Application Fields Assembly and maintenance of household appliances such as washing machines, air conditioners, refrigerators, water pumps, etc. Power electronics: Distribution boxes, switches, wiring terminals, and other applications that require conductive or grounded protection. Industrial equipment: flange sealing and connection for water pumps, valves, air compressors, small motors, and machine tool equipment. Automobile and motorcycle: oil and water pipeline connections in non core engine parts (such as motorcycle accessories). Hardware maintenance: universal screw fastening and sealing in daily home, pipeline, and furniture installation.
