Professional Applications & Engineering Value

This high-strength steel threaded rod delivers exceptional engineering value in industrial fastening systems where reliability is paramount. The fully threaded design with coarse UNC spacing provides maximum grip and adjustability in construction frameworks, machinery assembly, and structural supports. The Class 1A thread fit ensures smooth engagement while accommodating minor misalignments, reducing installation time and labor costs. With its 50,000 psi tensile strength and Rockwell B61 hardness, this rod effectively resists shear forces and vibrational loosening in heavy-duty applications. The inch-system compatibility makes it ideal for North American industrial standards, while the right-hand threading follows conventional installation practices for operator familiarity and efficiency.

Specification Summary & Compliance

This threaded rod features precision 1 1/4"-7 UNC coarse threading with Class 1A external thread fit per standard inch measurement specifications. The manufacturing complies with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, ensuring safe handling and usage. Mechanical properties include verified 50,000 psi tensile strength and Rockwell B61 hardness for consistent performance in industrial fastening applications requiring reliable load-bearing capabilities.
