Zinc Plated A193 B7 Stud Bolt with 2H Nut
Zinc plated A193 B7 stud bolt with 2H nut is a high-strength fastening assembly designed for industrial flange connections, pressure equipment, and heavy-duty mechanical applications. The zinc plated A193 B7 stud bolt with 2H nut combines ASTM A193 Grade B7 alloy steel stud bolts with ASTM A194 Grade 2H heavy hex nuts, providing reliable clamping force, excellent mechanical performance, and improved surface protection.
The zinc plated A193 B7 stud bolt with 2H nut is widely used in petrochemical plants, oil and gas equipment, pipelines, pressure vessels, power generation systems, and industrial machinery where strong and stable bolted connections are required.
Product Overview
The zinc plated A193 B7 stud bolt with 2H nut is a matched fastening set commonly used for high-pressure and high-temperature flange applications. The B7 stud bolt is manufactured from chromium-molybdenum alloy steel, offering high tensile strength and dependable mechanical properties. The 2H nut provides excellent load-bearing capability and thread engagement.
The zinc plating surface treatment improves corrosion resistance compared with untreated alloy steel and provides a uniform appearance. The zinc plated A193 B7 stud bolt with 2H nut is suitable for general industrial environments where moderate corrosion protection is required.
This fastening assembly is commonly supplied as a complete set for easier installation and better compatibility between stud bolts and nuts.
