S-94210A187 1/2"-20 x 3 ft. ASTM A193 Threaded Rods

Key Features & Benefits at a Glance

• Exceptional tensile strength of 125,000 psi for reliable performance in high-stress applications, reducing the risk of fastener failure.
• Superior corrosion resistance with black-oxide steel coating, extending service life in harsh industrial environments.
• Precision Class 2A thread fit ensures smooth assembly and secure fastening, minimizing installation time and errors.
• Fully threaded design provides uniform load distribution along the entire 3 ft length, enhancing structural integrity.
• High hardness (Rockwell C35) offers excellent wear resistance, maintaining thread integrity through repeated use.
• Compliance with RoHS 3 and REACH standards guarantees environmental safety and regulatory acceptance for global projects.
• Fine UNF threading (1/2"-20) delivers superior holding power and vibration resistance in critical assemblies.

Professional Applications & Engineering Value

This 1/2"-20 UNF threaded rod is engineered from ASTM Grade B7 black-oxide steel to address common industrial challenges such as corrosion, high tensile loads, and vibration loosening. The fully threaded configuration allows for adjustable nut positioning along the entire 3 ft length, ideal for construction, machinery anchoring, and structural bracing where precise tension control is critical. The fine thread spacing enhances grip in materials prone to stripping, while the black-oxide surface treatment provides a durable barrier against moisture and chemicals, reducing maintenance costs. Suitable for heavy-duty applications like pressure vessels and valve systems, it ensures long-term reliability under demanding conditions, backed by ASTM A193 specifications.

Specification Summary & Compliance

This threaded rod adheres to Class 2A thread fit tolerances for consistent external threading, meeting UNF fine thread standards (1/2"-20) with right-hand direction. Manufactured in compliance with ASTM A193 for ASTM Grade B7 material, it achieves a tensile strength of 125,000 psi and Rockwell C35 hardness. The product is RoHS 3 (2015/863/EU) Compliant and REACH (EC 1907/2006) Compliant, ensuring it meets stringent environmental and safety regulations for industrial use.
