Professional Applications & Engineering Value

This Grade 5 steel hex nut with 1-1/4"-7 UNC coarse threads is engineered to address critical fastening challenges in industrial settings. The Class 2B thread fit provides optimal clearance for rapid assembly while maintaining secure engagement, reducing installation time without compromising joint integrity. Manufactured from high-strength steel, it withstands high tensile and shear stresses in heavy-duty applications such as machinery assembly, structural frameworks, and transportation equipment. The standard hex profile and external drive style ensure compatibility with standard tools, facilitating maintenance and reducing downtime. Its coarse thread design resists vibration-induced loosening, making it ideal for dynamic load environments where reliability is paramount.

Specification Summary & Compliance

This hex nut features 1-1/4"-7 UNC coarse threads with Class 2B fit per ASME B18.2.2 standards, ensuring precise dimensional accuracy and interchangeability. The right-hand thread direction and standard inch system measurements (1-7/8" width, 1-1/16" height) provide consistent performance. It complies with ASME B18.2.2 manufacturing specifications, RoHS 3 (2015/863/EU) for hazardous substance restrictions, and REACH (EC 1907/2006) regulations for chemical safety, meeting rigorous industrial and environmental requirements.
