KM black plated flat head screws, furniture screws, cross recessed countersunk head machine screws, screws, M2 M3 M4 M5

Product advantages:Suitable for use in dry, non-corrosive environments

• The countersunk design does not protrude:The head features a countersunk (flat head) structure, which can be embedded into the surface of the workpiece after installation, without being exposed or scratching. It maintains the flatness and aesthetics of the assembly surface, making it particularly suitable for furniture, equipment panels, decorative parts, and other scenarios where appearance flatness is required.
• Rust-proof, corrosion-resistant, and more durable: The black surface undergoes multiple treatments such as oxidation blackening. Some high-end models can even achieve high salt spray resistance and heat and humidity resistance, which can isolate the base material from air and moisture, preventing rust and oxidation. It is suitable for both indoor dry environments and mildly humid outdoor scenarios, extending the service life of screws and workpieces.
• Tight fastening, stable adaptability, and wide range: The machine screw thread design ensures uniform stress distribution and strong fastening force. Some styles with a bit of adhesive technology can further enhance the anti-loosening ability, even for equipment prone to vibration such as motors and gearboxes, it can prevent the connection parts from loosening. Moreover, the specifications cover a wide range from commonly used micro sizes such as M1.4 to M4 to conventional sizes, adapting to various substrates such as metal, plastic, and wood.
