- Fully threaded design offers maximum adjustability and secure fastening along the entire 4-foot length for versatile installation.
- Precision UNC coarse threading with Class 2A fit ensures easy assembly and consistent engagement with compatible nuts and components.
- ASTM A193 Grade B7 steel construction delivers proven durability and corrosion resistance for industrial and construction applications.
- Compliance with RoHS 3 and REACH regulations guarantees environmental safety and unrestricted use in regulated markets.
- Right-hand thread direction provides standard, intuitive installation for efficient workflow and reduced assembly errors.
Professional Applications & Engineering Value
This 5/16"-18 UNC threaded rod is engineered from ASTM A193 Grade B7 steel, making it ideal for heavy-duty industrial applications such as structural supports, machinery assembly, and pressure vessel systems. The fully threaded configuration allows for precise tension adjustment and secure connections across long spans, while the coarse UNC threading resists loosening under vibration. With a tensile strength of 125,000 psi and Rockwell C35 hardness, it addresses critical needs for load-bearing capacity and durability in harsh operating conditions, minimizing maintenance and replacement costs.
Specification Summary & Compliance
This threaded rod meets Class 2A thread fit tolerances for consistent external threading, adhering to UNC coarse thread standards. It is manufactured in compliance with ASTM A193 specifications for high-temperature service and is verified as RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) compliant, ensuring environmental and safety standards are met for industrial use.
