Material Characteristics & Production Process
The bolts are manufactured using AISI 304 stainless steel, an austenitic grade known for excellent corrosion resistance, good formability, and high weldability. The production process involves:
- Raw Material Sourcing
- Cold or Hot Forging
- Thread Rolling (fine pitch cutting with precise tolerance)
- Heat Treatment (if required)
- Surface Polishing/Passivation
- Final Quality Control and Packaging
Each step ensures that 304 SS Fine Pitch Thread Hexagon Bolts DIN961 perform reliably in demanding environments.
Typical Applications and Industries
These fine-thread hexagon bolts are widely used in:
- Automotive engines and transmission systems
- Aerospace assemblies
- Precision machinery
- Renewable energy systems
- Marine equipment exposed to corrosive environments
- Electronic device mounting and structural frames
Due to their precise threading and corrosion-resistant material, they are particularly suited for high-vibration settings where threaded security is critical.
