The Heavy-Duty Carriage Bolt Hot-Dip Galvanized to ASTM A153 is a structural fastener designed for outdoor construction, utility installations, wooden structures, and steel frameworks. Its hot-dip galvanized coating complies with ASTM A153 requirements, ensuring exceptional corrosion resistance and long service life even in harsh, humid, or coastal environments. The round head and square neck design provide secure positioning and anti-rotation performance during tightening.
• ASTM A153 hot-dip galvanizing ensures durable corrosion protection
• Ideal for outdoor and high-moisture environments
• Square neck prevents bolt rotation during installation
• High tensile strength suitable for heavy-load structures
• Provides stable fastening for wood, steel, and utility systems
• Long-term surface protection reduces maintenance needs
Outdoor Wooden Structures: Inserted through pre-drilled holes in beams or boards; the square neck locks into the wood to prevent spinning during tightening.
Utility Pole Hardware & Power Distribution Equipment: Used to fasten brackets, clamps, or crossarms; the galvanized coating ensures long life under outdoor electrical infrastructure conditions.
Steel Frame Construction: Bolts pass through steel plates and are secured with heavy-duty nuts; the HDG coating resists rust during long-term exposure.
Outdoor Furniture, Fences, and Landscaping Structures: Used in assembly of benches, fences, or pergolas; the rounded head offers a smooth, safe appearance.
Coastal, Humid, or Industrial Environments:The HDG coating prevents oxidation; bolts maintain structural integrity even with continuous salt or chemical exposure.
Each bolt undergoes rigorous quality control to ensure compliance with international standards. Custom sizes and packaging are also available to meet specific project needs.
