Professional Applications & Engineering Value

This 1/4"-20 UNC threaded rod is engineered from ASTM A193 Grade B7 black-oxide steel to address critical challenges in industrial settings, such as structural instability and corrosion-induced degradation. The fully threaded configuration with coarse threads allows for rapid adjustments in machinery assembly, piping systems, and construction frameworks, where precise tension control is vital. Its high tensile strength and hardness make it ideal for heavy-duty applications like pressure vessel anchoring and valve installations, resisting deformation under load. The black-oxide surface treatment not only enhances durability against moisture and chemicals but also reduces friction during installation, streamlining workflows. By integrating right-hand threading and standardized dimensions, it ensures compatibility with common Class 2A fittings, minimizing downtime and boosting operational reliability in sectors from oil and gas to manufacturing.

Specification Summary & Compliance

This threaded rod adheres to Class 2A thread fit tolerances for consistent engagement, with UNC coarse threading per standardized dimensions. It meets ASTM A193 specifications for material and performance, including a tensile strength of 125,000 psi and Rockwell C35 hardness. The product is fully RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) compliant, ensuring it meets stringent environmental and safety regulations for industrial use.
