Product advantages:

Precision Machining

☆ Measure and process using precision machine tools and measuring tools under strictly controlled environmental conditions.

High-quality carbon steel(35#/45#)

☆ With long life, low heat generation, high hardness, high rigidity, low noise, high wear resistance and other characteristics.

Cost-effective

☆ The use of high-quality carbon steel steel, after precision processing and forming, greatly improves the user experience.

Surface treatment:

Black Oxide

☆ 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.

Hot dip galvanized Hexagon Bolt
