Manufacturing Processes for  Bronze Screws, Silicon bronze Screws, Silicon bronze fasteners and Bronze Machine Screws

We manufacture Bronze machine screws and Bronze fasteners using advanced production techniques to ensure high strength, precision, and durability:

  • Cold Forging – Used for mass production, enhances strength through work hardening.
  • Roll Threading – Creates precise and uniform threads with improved tensile strength.
  • CNC Machining – Ensures tight tolerances and complex geometries for custom screws.
  • Heat Treatment – Used for strength enhancement and stress relief.
  • Surface Finishing – Polishing, tin plating, passivation, and nickel coating for added corrosion resistance.

Applications of Bronze Machine Screws

Bronze machine screws are utilized in various industries where high durability and corrosion resistance are required:

  • Marine & Offshore – Used in shipbuilding, docks, and underwater applications due to excellent saltwater resistance.
