Professional Applications & Engineering Value

This 1/2"-20 UNF threaded rod is engineered to solve critical challenges in industrial fastening and heavy-duty construction. Made from ASTM Grade B7 black-oxide steel, it combines high tensile strength (125,000 PSI) and Rockwell C35 hardness to withstand extreme mechanical loads and thermal cycling. The fully threaded design with right-hand fine threads ensures uniform stress distribution, preventing loosening under vibration—common in machinery, structural framing, and pressure vessel systems. The black-oxide surface treatment adds a protective layer against rust and abrasion, reducing maintenance costs in corrosive environments like chemical plants or outdoor installations. By adhering to ASTM A193, this rod delivers consistent performance where failure is not an option.

Specification Summary & Compliance

This threaded rod meets Class 2A thread fit tolerances per UNF standards, with fine thread spacing for precise engagement. It conforms to ASTM A193 Grade B7 material specifications and is manufactured to deliver 125,000 PSI tensile strength and Rockwell C35 hardness. Compliance includes RoHS 3 (2015/863/EU) and REACH (EC 1907/2006), ensuring adherence to environmental and safety regulations for industrial components.
