Fasteners and General Small Parts

 Fasteners and general small parts are commonly used basic mechanical components. They feature a wide range of specifications, diverse performance and applications, standardization, mass production, and a high degree of versatility. To improve the corrosion resistance of fasteners and maintain their aesthetic appearance, fasteners are usually subjected to surface treatment. Common surface treatments include galvanization, zinc-nickel plating, and Dacromet coating. In the manufacturing of fasteners and small parts, the thickness of the coating directly affects corrosion resistance, wear resistance, and performance. Coating analyzers can be used for quality control to ensure that the coating thickness of each part is within the specified limits, thereby maintaining product consistency and quality.
