What are the precautions for using press - riveted nut studs in the automotive manufacturing industry
Ensure that the material of the press - riveted nut studs matches the material of the automotive components to prevent electrochemical corrosion between different metals. For example, if the automotive component is made of aluminum alloy, the press - riveted nut studs should also be made of aluminum alloy or a material with good compatibility with it.
Strength requirements: Select the strength grade (such as stainless steel or carbon steel) according to the stress scenario, which must comply with automotive industry standards (e.g., ISO 15983).
Surface treatment: Galvanizing, phosphating, or Dacromet treatment can improve corrosion resistance. However, it is necessary to avoid the coating from affecting the press - riveting performance.
During use, automobiles are exposed to various harsh environmental conditions, such as humidity and salt spray, which can easily cause the press - riveted nut studs to rust and corrode. Therefore, appropriate surface treatments, such as galvanizing or nickel - plating, should be applied to the press - riveted nut studs to enhance their corrosion resistance.
In some special usage environments, such as vehicles driven in coastal areas or on roads salted in winter, materials or protective coatings with higher corrosion resistance can be selected.
Vibrations and shocks are generated during the operation of automobiles. The press - riveted nut studs need to have good vibration and shock resistance. Methods such as optimizing the design, selecting appropriate materials, and proper installation methods can be used to improve their vibration and shock resistance. For example, press - riveted nut studs with anti - loosening designs or auxiliary measures such as adding washers can be adopted.
