Quantity
The Threaded Metal Rod is a high-performance double-end stud engineered for critical bolting applications in the oil and gas, petrochemical, and power generation industries. Manufactured in strict compliance with API 20E BSL 2 (Bolting Specification Level 2), this rod undergoes rigorous material traceability, manufacturing process control, and lot-level testing to ensure the highest level of quality assurance for sour service and elevated-temperature environments.
Material & Mechanical Properties
Crafted from ASTM A193 B7 – a chromium-molybdenum alloy steel widely recognized for its excellent tensile strength, toughness, and resistance to stress corrosion cracking – this Threaded Metal Rod delivers reliable clamping force under cyclic loading and thermal expansion. The material is heat-treated to achieve consistent hardness and ductility, making it suitable for flange connections, pressure vessels, valves, and structural supports where joint integrity is non-negotiable.

Dimensions & Thread Configuration
This model features a nominal size of 1-1/8 inches and an overall length of 5.75 inches, with double-end threading that allows simultaneous engagement of two mating components – ideal for blind-hole installations or applications requiring stud-and-nut assemblies on both ends. The thread specification is 8 UN (Unified National constant pitch) with a Class 2A external tolerance, ensuring a precision fit with standard heavy hex nuts and reducing the risk of galling during make-up.

Surface Protection
The rod is finished with a yellow zinc coating, which provides robust corrosion resistance in moderate to severe atmospheric conditions while offering a distinctive, easily identifiable appearance. This coating also acts as a lubricious layer that facilitates consistent torque-tension relationships during installation, improving joint reliability and reducing field assembly time.
