1-8 UNC *5" Alloy Steel ASTM A193 B7 Threaded Rods

ASTM A193 B7: The Gold Standard for High-Performance Fastening
Crafted from premium alloy steel and heat-treated to ASTM A193 Grade B7 specification, these rods achieve exceptional tensile strength (minimum 125 ksi) and yield resistance. 
B7 grade is specifically engineered for high-temperature service up to 800°F (427°C), making it ideal for steam systems, oil refineries, and boiler applications where ordinary fasteners would fail.
The chromium-molybdenum alloy composition ensures superior creep resistance and long-term structural integrity under sustained load.

Precision Imperial Threading: 1-8 UNC × 5"
Featuring a 1-inch diameter with 8 threads per inch (UNC coarse thread) and a precise 5-inch length, this rod adheres to strict Imperial system tolerances for seamless compatibility with standard heavy-duty nuts and flanged connections. 
The coarse UNC thread profile enables faster assembly, reduces cross-threading risk, and distributes clamping force evenly—critical for leak-free seals in high-vibration environments.

Galvanized Surface for Enhanced Corrosion Protection
Every rod receives a high-quality zinc galvanization (Galv) coating, creating a robust sacrificial barrier against rust, moisture, and chemical exposure. 
This protective layer extends service life in outdoor, marine, or industrial atmospheres while maintaining smooth thread engagement and consistent torque performance.

Flexible Specifications & Full Customization
While B7 alloy steel excels in high-heat applications, we support a complete range of grades to match your project needs: 4.8, 8.8, L7, B8, B8M, B8T, and B8C. 
We offer both Metric and Imperial measurement systems and fully support OEM/ODM customization—tailoring length, thread pitch, coating, or material to your exact specifications.
