Professional Applications & Engineering Value

This 1/4"-20 UNC threaded rod delivers critical engineering solutions where structural integrity and long-term performance are paramount. The zinc-plated steel construction prevents corrosion in manufacturing facilities, construction sites, and outdoor installations, while the fully threaded design allows for adjustable positioning and secure fastening across extended spans. The coarse UNC threading provides superior resistance to vibration loosening compared to fine threads, making it ideal for industrial machinery, structural frameworks, and heavy-duty equipment assembly. With consistent Class 1A thread fit throughout its 8-foot length, this rod eliminates installation inconsistencies and reduces assembly time in production environments.

Specification Summary & Compliance

This threaded rod meets UNC coarse thread standards with Class 1A thread fit for external threading applications. Manufacturing specifications include 1/4"-20 thread size, right-hand thread direction, and full threading along the entire 8-foot length. The product demonstrates 50,000 psi tensile strength and Rockwell B61 hardness for consistent mechanical performance. Compliance includes RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring environmental safety and regulatory acceptance for industrial use.
