S-95625A142 5/16"-24 x 6 ft. ASTM A193 Threaded Rods

Key Features & Benefits at a Glance

• Superior tensile strength of 125,000 psi ensures reliable performance under high-stress conditions, reducing the risk of fastener failure in critical applications.
• Exceptional hardness (Rockwell C34) provides excellent wear and deformation resistance, extending service life in abrasive or high-load environments.
• Left-hand threading offers specialized fastening solutions for applications requiring reverse rotation to prevent loosening from standard right-hand motion.
• Fully threaded design allows for adjustable nut positioning along the entire 6-foot length, providing versatile installation and assembly flexibility.
• Precise Class 2A thread fit with UNF fine spacing ensures smooth engagement and secure connections, minimizing cross-threading risks.
• ASTM A193 compliance guarantees material quality and manufacturing consistency for high-temperature and high-pressure service applications.
• RoHS 3 compliance ensures environmental safety and regulatory adherence for use in restricted substance-sensitive industries.

Professional Applications & Engineering Value

This 5/16"-24 UNF left-hand threaded rod delivers critical engineering solutions where standard right-hand fasteners would fail. Manufactured from ASTM Grade B7 steel, it maintains structural integrity in high-temperature environments up to 800°F (427°C), making it ideal for pressure vessel systems, valve assemblies, and petrochemical equipment. The fully threaded configuration provides unlimited adjustment points for precise component alignment, while the left-hand thread direction prevents accidental loosening in rotating machinery where counter-clockwise motion occurs. With fine thread spacing offering superior vibration resistance compared to coarse threads, this rod ensures lasting stability in industrial settings requiring reliable reverse-threading capabilities.

Specification Summary & Compliance

This threaded rod features 5/16"-24 UNF left-hand threads with Class 2A thread fit per ASME B1.1 standards, ensuring precise dimensional accuracy and interchangeability. The ASTM Grade B7 steel construction meets ASTM A193 specifications for high-temperature bolting materials, while the 125,000 psi tensile strength and Rockwell C34 hardness provide documented mechanical properties. Manufacturing compliance includes RoHS 3 (2015/863/EU) environmental directives, making it suitable for regulated industrial applications requiring verified material composition.
