S-95625A005 1/4"-28 x 3 ft. ASTM A193 Threaded Rods

Key Features & Benefits at a Glance

• Exceptional tensile strength of 125,000 psi ensures reliable performance in high-stress applications, reducing the risk of fastener failure.
• High hardness rating (Rockwell C35) provides superior wear resistance and longevity, minimizing replacement frequency and maintenance costs.
• Left-hand threading offers secure fastening in applications where standard right-hand threads may loosen due to rotational forces.
• Fully threaded design allows for adjustable nut placement along the entire 3-foot length, providing versatile installation options.
• Precision Class 2A thread fit ensures smooth assembly and consistent engagement with mating components, reducing installation time.
• Compliance with ASTM A193, RoHS 3, and REACH guarantees material quality and environmental safety for use in regulated industries.
• UNF fine threading delivers higher resistance to vibration loosening compared to coarse threads, enhancing joint integrity.

Professional Applications & Engineering Value

This Grade B7 steel threaded rod is engineered to address critical challenges in demanding environments such as pressure vessels, valve systems, and structural assemblies. The left-hand UNF fine threads are particularly valuable in rotating machinery where reverse-direction threading prevents unintended loosening. With a 125,000 psi tensile strength and Rockwell C35 hardness, it withstands extreme mechanical stresses and corrosive conditions common in chemical processing, oil and gas, and power generation applications. The fully threaded 3-foot length provides flexibility for custom fabrication while maintaining ASTM A193 compliance for high-temperature service. Its RoHS 3 and REACH compliance ensures suitability for projects with strict environmental and safety regulations.

Specification Summary & Compliance

This threaded rod features 1/4"-28 UNF fine threads with Class 2A external thread fit per ASME B1.1 standards, ensuring precise dimensional accuracy. Manufactured from ASTM A193 Grade B7 steel, it meets mechanical property requirements including tensile strength and hardness. The product is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, confirming the absence of restricted hazardous substances. This combination of specifications makes it suitable for high-performance industrial fastening applications where reliability and regulatory adherence are critical.
