Material Introduction & Manufacturing Process
The 304 SS Passivation Hex Threadlocker Coated Bolt is made from premium 304 grade stainless steel known for its corrosion resistance and strength. The passivation process involves chemically removing free iron and surface contaminants, forming a chromium-rich oxide layer that enhances corrosion resistance.
The manufacturing process includes:
- Cold forging to shape the hex head.
- Thread rolling for precision threading.
- Heat treatment (if required for strength).
- Passivation to increase corrosion resistance.
- Application of threadlocker coating to threads.
- Final inspection and packaging.
These steps ensure a consistent, high-quality product tailored to exact application needs.
Common Industries and Applications
The bolt finds essential use across a diverse range of industries:
- Automotive (Engine assemblies, exhaust systems)
- Construction (Steel frameworks, anchor bolting)
- Marine (Boat deck fittings)
- Renewable Energy (Wind turbine components)
- Aerospace & Defense (Vibration-sensitive connections)
- Industrial Machinery (Heavy-duty machine parts)
With its advanced thread-locking protection and corrosion resistance, it’s a preferred choice in high-vibration environments.
