DIN934 Hot Dipped Galvanized M16 Hex Nut Grade8 Hot-Dip Galvanized (HDG) Hex Nuts represent the pinnacle of corrosion-resistant fastening technology. Engineered for extreme environments, these nuts undergo a metallurgical bonding process where zinc forms a series of zinc-iron alloy layers (Gamma, Delta, Zeta) topped by pure zinc (Eta layer). This creates a barrier protection exceeding 65 microns, offering 3-5× longer service life than electroplated alternatives. ENGINEERED ADVANTAGES: WHY OUR HDG NUTS OUTPERFORM a) Superior Corrosion Resistance - Salt spray resistance: 1,500+ hours (ASTM B117)
b) Uncompromising Mechanical Performance
- Proof load: 90,000 PSI (Grade A) to 120,000 PSI (Grade C)
- Hardness: 70-100 HRB (Rockwell B Scale)
- Temperature tolerance: -40°C to 150°C (-40°F to 302°F)
c) Precision Manufacturing
- CNC cold forging with 0.02mm dimensional tolerance
- Class 6H thread fit (ISO 965-1) for vibration resistance
- Radiused corners prevent flange damage
d) Installation Advantages
- Zinc lubrication reduces torque friction by 25% vs. plain nuts
- Chamfered top edge enables 30% faster alignment
- No hydrogen embrittlement risk (unlike electroplated nuts)
e) Economic Efficiency - 50-year maintenance-free service in C3 environments (ISO 12944) - Reduced lifecycle costs vs. stainless steel (304/316) - Recyclable zinc coating (ISO 14001 compliant process)
