Key Features & Benefits at a Glance
- Exceptional tensile strength of 125,000 psi provides reliable performance in high-stress applications, reducing the risk of fastener failure.
- Superior corrosion resistance from the black-oxide steel finish extends service life in harsh industrial environments, minimizing maintenance needs.
- Precise Class 2A thread fit ensures smooth assembly and secure connections, enhancing installation efficiency and joint integrity.
- Fully threaded 3 ft length offers versatile adjustability and continuous engagement, ideal for custom fabrication and structural bracing.
- High hardness (Rockwell C35) resists wear and deformation under load, maintaining dimensional stability over time.
- Compliance with ASTM A193 guarantees material quality and manufacturing consistency, meeting rigorous industry standards for safety.
- Fine UNF thread spacing delivers improved clamping force and vibration resistance compared to coarse threads, suitable for precision equipment.
Professional Applications & Engineering Value
Engineered for demanding industrial settings, this 1/4"-28 UNF threaded rod in ASTM Grade B7 black-oxide steel addresses critical challenges like corrosion, fatigue, and mechanical stress. Its fully threaded design and right-hand thread direction facilitate easy integration into structural frameworks, machinery anchoring, and piping systems, where consistent tensile strength and fine thread spacing prevent loosening under dynamic loads. The black-oxide surface treatment provides a durable barrier against moisture and chemicals, making it ideal for oil and gas, construction, and heavy equipment applications that require long-term reliability without frequent replacements.
Specification Summary & Compliance
This threaded rod features a Class 2A thread fit per UNF standards, ensuring dimensional accuracy for external threading. It conforms to ASTM A193 for material specifications and is manufactured to deliver consistent 125,000 psi tensile strength and Rockwell C35 hardness. The product is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, supporting environmental and safety standards in global supply chains.
