It is used to connect the fixed link function of the machine. The stud bolts are threaded at both ends, and the middle screw is thick or thin. Generally used in mining machinery, bridges, automobiles, motorcycles, boiler steel structures, suspension towers, large-span steel structures and large buildings.
Stud bolts generally require surface treatment. There are many types of bolt surface treatments. Generally, plating, blackening, oxidation, phosphating, and non-electrolytic zinc sheet coating are commonly used. However, electroplated fasteners occupy a large proportion in the actual use of fasteners. It is more widely used in industries and fields such as automobiles, tractors, home appliances, instrumentation, aerospace, and communications.
Surface Treatment
Black
Black is a common method for metal heat treatment. The principle is to make an oxide film on the metal surface to isolate the air and achieve rust prevention. Blackening is a common method for metal heat treatment. The principle is to make an oxide film on the metal surface to isolate the air and achieve rust prevention.
Zinc
Electro-galvanizing is a traditional metal coating treatment technology that provides basic corrosion resistance to metal surfaces. The main advantages are good solderability and suitable contact resistance. Due to its good lubrication properties, cadmium plating is commonly used in aviation, aerospace, marine, and radio and electronic products. The plating layer protects the steel substrate from both mechanical and chemical protection, so its corrosion resistance is much better than zinc plating.
Hdg
The main advantages are good solderability and suitable contact resistance. Due to its good lubrication properties, cadmium plating is commonly used in aviation, aerospace, marine, and radio and electronic products. The plating layer protects the steel substrate from both mechanical and chemical protection, so its corrosion resistance is much better than zinc plating. Hot-dip zinc has good corrosion resistance, sacrificial protection for steel substrates, high weather resistance, and resistance to salt water erosion. It is suitable for chemical plants, refineries and coastal and offshore operating platforms.
