• Fully threaded design offers versatile installation and adjustment capabilities along the entire 3-foot length, ideal for custom assembly needs.
• Precision UNC coarse threading with Class 2A fit enables quick assembly and secure fastening, minimizing installation time and labor costs.
• ASTM A193 Grade B7 compliance guarantees material quality and performance consistency for critical high-temperature and high-pressure applications.
• RoHS 3 compliance ensures environmental safety and regulatory adherence, making it suitable for global industrial supply chains.
• Right-hand thread direction with coarse spacing facilitates standard tool compatibility and efficient manual or automated installation.

Professional Applications & Engineering Value

This 1/4-20 UNC threaded rod is engineered to address critical challenges in industrial fastening where high tensile strength and durability are paramount. Constructed from ASTM Grade B7 steel, it withstands extreme mechanical loads and temperatures up to 800°F (427°C), preventing thread stripping and structural failures in heavy-duty applications like pressure vessel systems, structural anchoring, and machinery assembly. The fully threaded right-hand design with coarse UNC spacing ensures rapid installation and adjustability, while the Class 2A thread fit maintains precise engagement for vibration resistance. Its Rockwell C35 hardness combats abrasion in corrosive environments, reducing maintenance frequency and downtime in sectors such as oil and gas, construction, and manufacturing.

Specification Summary & Compliance

This threaded rod adheres to inch system dimensions with a 1/4"-20 UNC thread size and Class 2A thread fit for standardized compatibility. It meets ASTM A193 specifications for alloy steel fasteners in high-temperature service, with RoHS 3 (2015/863/EU) compliance ensuring restriction of hazardous substances. The manufacturing process follows ASME-aligned guidelines for thread spacing and dimensional accuracy, supporting consistent performance in industrial applications requiring reliable tensile strength and threading precision.
