Product Description
Types of Galvanization
Our hex bolts feature two premium galvanization options:
- Hot-Dip Galvanizing (HDG): Immersion in molten zinc (≈450°C) creates a thick zinc-iron alloy layer (50–150 μm) for superior corrosion resistance (50+ years in mild environments), ideal for outdoor/marine applications.
- Electro-Galvanizing: Electrolysis deposits a thin zinc coating (5–25 μm) that maintains precise thread dimensions, suitable for indoor/dry environments.
Key Applications
- Construction: Structural steel connections, roofing, HVAC systems
- Automotive: Chassis components, trailers, marine equipment
- Energy: Power line towers, wind turbines, solar panel mounts
- Agriculture/Marine: Farm machinery, irrigation systems, boat fittings
- General Manufacturing: Machinery assembly, pipelines, industrial equipment
Technical Advantages
- Simplified assembly with integrated flange (no separate washer)
- Enhanced stability against vibration and loosening
- Cost-effective solution with reduced component count
- Compatible with standards: DIN 6921, ISO 4161, ASME/ANSI
