Production of galvanized screws
The production of galvanized screws is an essential industrial process to give products superior protection against corrosion. Galvanized screws are screws that have undergone a galvanizing treatment, a process that involves applying a thin layer of zinc to the surface of the screw . This zinc coating serves to protect the underlying metal from rust and atmospheric agents, ensuring greater durability and resistance over time. Thanks to this treatment, the galvanized screws do not rust. Galvanized screws are widely used in several industries, including construction, automotive and furniture manufacturing, due to their combination of strength and corrosion resistance.
Galvanized screws: the types
White galvanized screws
Treated with a white galvanization, these screws offer good corrosion resistance and a shiny appearance. They are ideal for applications where aesthetics are important , such as in the production of furniture and architectural finishes.
Yellow galvanized screws
This type of galvanization gives the screws a golden appearance, providing superior protection against corrosion. Yellow galvanized screws are often used in marine environments and other harsh conditions where chemical resistance is essential.
Black galvanized screws
Black galvanizing gives the screws a dark, matt appearance, as well as reliable anti-corrosion protection. They are particularly suitable for industrial and automotive applications where a discreet appearance and high robustness are required.
Zinc-nickel screws
Zinc-nickel coated screws combine the corrosion resistance of zinc with the hardness of nickel. They are particularly suitable for automotive and heavy industrial applications , where superior mechanical and chemical resistance is required.

Galvanized screws:
types of threads
- ISO metric threads : These threads, characterized by a triangular profile, are available in different variants:
- Coarse pitch : Ideal for general applications, they offer good mechanical resistance.
- Fine pitch : Used where greater precision and tightness is required.
- Multi-start : They allow faster advancement of the screw compared to standard threads.
- Double helix : They offer an increase in speed in assembly and disassembly.
- Left-hand thread : Used in applications where reverse rotation could loosen the screw.
- Self-forming tri-lobes : Designed to form self-threads in the target material, ensuring a secure installation without the need for pre -threading.
- Whitworth threads : British standard, these threads are mainly used in heavy mechanical applications and in industrial plants.
- ASA UNC and UNF series threads : American standard, these threads are divided into UNC ( Unified National Coarse ) and UNF ( Unified National Fine), used in various industries, including automotive and aerospace.
- Sawtooth Threads : Featuring an asymmetric sawtooth profile, these threads are ideal for applications where greater resistance to tensile stress is required.
- Special custom threads : Vilux Viterie is able to create tailor-made threads according to the customer’s specific needs, guaranteeing customized solutions for each application.
