Professional Applications & Engineering Value

This carbon steel threaded rod with dual right-hand and left-hand threading solves critical engineering challenges in machinery assembly, automotive systems, and industrial equipment where counter-rotational forces must be managed. The hex rod configuration prevents rotation during installation, eliminating the need for secondary locking mechanisms. With both ends threaded to 1-1/4" depth, this component provides exceptional load distribution and vibration resistance in dynamic applications. The 3/8"-24 thread size maintains compatibility with standard industrial components while the carbon steel material ensures reliable performance under mechanical stress and environmental exposure.

Specification Summary & Compliance

This 4-inch threaded rod features 3/8"-24 UNC threads with standard Class 2A tolerance for consistent fit. Manufactured from carbon steel with hex shape (3/8" across flats) and 1-1/4" thread length on both ends. Compliant with RoHS 3 (2015/863/EU) under exemption 6(a) for lead as steel alloying element and REACH (EC 1907/2006) regulations current through January 2023 SVHC list.
