These hot-dip galvanized L7 bolts for Russia are suitable for applications where both mechanical strength and corrosion resistance are critical.

Material and Coating Advantages

ASTM A193 Grade L7 is widely recognized for its excellent tensile strength and reliability in high-stress bolting applications. Combined with hot-dip galvanizing, the bolt and nut assemblies offer:

• Enhanced corrosion resistance in outdoor and harsh environments
• Long service life in industrial and energy projects
• Strong resistance to mechanical fatigue and load variation

Such BS 4882 bolt and nut assemblies are commonly used in steel structures, pressure equipment, pipeline flanges, and heavy machinery installations.

Quality Control and Export Assurance

Before shipment, all bolts and nuts were subjected to strict quality checks, including:

• Dimensional inspection of diameter, length, and thread tolerance
• Visual inspection of galvanized coating thickness and uniformity
• Verification of material grade and standard compliance

Haihao Group ensures that every hot-dip galvanized stud bolt and nut set meets project specifications and international standards.
