A double-thread screw for car lights, with a strength of 10.9 and excellent corrosion resistance, can last for 1000 hours in a neutral salt spray environment without rusting.
1. Product use
The double-thread screw for car lights is mainly used to fix the headlight components to ensure that the lights remain stable during the driving of the vehicle. It can tightly connect the lights to the body to prevent the lights from loosening or shifting due to vibration or bumps, thereby ensuring driving safety. Whether it is a headlight, taillight, or fog light, the double-thread screw can provide a reliable fixation for it.
2. Product advantages
High strength: Made of high-quality steel, it has undergone a strict heat treatment process has extremely high strength and hardness, and can withstand various stresses during vehicle driving.
Corrosion resistance: The surface has undergone special anti-corrosion treatment, which can effectively resist corrosion factors such as rain, dust, and oil, and extend the service life of the screw.
Precise size: The high-precision processing technology is used to ensure the dimensional accuracy of the screw, so that it can perfectly match the mounting holes of the headlight and the body, making installation more convenient and quick.
Double-head design: The unique double-headed thread design makes the screws more secure during installation and not easy to loosen. At the same time, it also facilitates the disassembly operation when repairing and replacing the headlights.
3. Manufacturing process
Material selection: Select high-quality high-strength steel to ensure the performance and quality of the screws.
Processing: Use advanced automated processing equipment to perform cutting, drilling, tapping, and other processing processes on the steel to ensure the dimensional accuracy and surface quality of the screws.
Heat treatment: Heat treatment is performed on the processed screws to improve their strength and hardness and make them more durable.
Surface treatment: Electroplating, galvanizing, spraying, g, and other surface treatment processes are used to enhance the corrosion resistance of the screws and make their appearance more beautiful.
