S-98957A129 5/16"-24 x 1.5 ft. ASTM A193 Threaded Rods

Key Features & Benefits at a Glance

• Exceptional tensile strength of 125,000 psi ensures reliable performance under high-stress conditions, reducing the risk of fastener failure.
• Premium ASTM Grade B7 steel construction provides superior durability and resistance to deformation in demanding industrial environments.
• Full UNF fine threading with Class 2A fit offers precise engagement and vibration resistance for secure, long-lasting assemblies.
• Rockwell C35 hardness enhances wear resistance, extending service life in high-friction applications.
• Full 1.5-foot length and right-hand threading allows for versatile installation and easy integration into existing systems.
• Compliance with ASTM A193, RoHS 3, and REACH guarantees material quality and environmental safety for regulated industries.
• Fine thread spacing (24 TPI) provides improved clamping force and better load distribution compared to coarse threads.

Professional Applications & Engineering Value

This 5/16"-24 UNF threaded rod delivers critical engineering value in applications where high tensile strength and precise threading are paramount. Manufactured from ASTM Grade B7 steel, it addresses common industrial challenges such as bolt stretching under heavy loads and thread stripping in vibrating machinery. The fully threaded design with UNF fine threads ensures maximum thread engagement across the entire length, providing superior resistance to loosening in dynamic systems. This makes it ideal for pressure vessel assemblies, structural frameworks, and heavy machinery where 125,000 psi tensile strength and Rockwell C35 hardness prevent premature wear and maintain joint integrity. Its compliance with international standards makes it suitable for oil and gas, chemical processing, and construction sectors requiring reliable, high-performance fastening solutions.

Specification Summary & Compliance

This threaded rod meets precise dimensional standards with Class 2A thread fit and UNF fine thread specification (5/16"-24). It is manufactured in accordance with ASTM A193 for high-temperature service and complies with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring it is free from hazardous substances. The inch-system measurement, right-hand thread direction, and full threading along the 1.5-foot length provide consistent performance and interoperability with standard industrial components.
