S-94210A125 1/4"-20 x 6 ft. ASTM A193 Threaded Rods

Key Features & Benefits at a Glance

• Exceptional tensile strength of 125,000 psi ensures reliable performance in demanding structural and mechanical applications.
• Superior corrosion resistance from the black-oxide steel finish prolongs service life in harsh industrial environments.
• Precision Class 2A thread fit guarantees smooth assembly and secure fastening with compatible nuts and components.
• Fully threaded 6-foot length provides versatility for custom cutting and extended reach in construction and machinery setups.
• High hardness (Rockwell C35) reduces wear and deformation under heavy loads, maintaining thread integrity over time.
• Compliance with ASTM A193 and RoHS 3 assures adherence to rigorous industry standards for safety and environmental responsibility.
• Coarse UNC threading enables quick installation and resistance to loosening in high-vibration applications.

Professional Applications & Engineering Value

This 1/4"-20 UNC threaded rod is engineered to address common industrial challenges such as corrosion, high-stress fatigue, and assembly efficiency. Made from ASTM Grade B7 black-oxide steel, it combines high tensile strength (125,000 psi) with a protective oxide coating that resists rust and oxidation in humid or chemical-exposed settings. The fully threaded design and coarse thread spacing allow for adjustable positioning and rapid installation in frameworks, piping systems, and machinery bases. Ideal for construction, oil and gas, and heavy equipment applications, this rod ensures long-term reliability and reduces maintenance costs by withstanding dynamic loads and environmental wear.

Specification Summary & Compliance

This threaded rod features a 1/4"-20 UNC coarse thread with Class 2A thread fit for precise dimensional accuracy. It meets ASTM A193 specifications for high-temperature service and is manufactured from ASTM Grade B7 material with a hardness of Rockwell C35. The product is RoHS 3 (2015/863/EU) compliant under exemption 6(a) for lead as an alloying element in steel, ensuring environmental safety without compromising mechanical performance.
