Professional Applications & Engineering Value

This Grade 5 steel hex nut delivers exceptional engineering value through its balanced combination of high tensile strength and precise UNC coarse threading. The 1/2"-13 thread size with Class 2B fit provides reliable fastening in heavy machinery, structural steel connections, and industrial equipment where vibration resistance is critical. The standard hex profile and 3/4" width ensure compatibility with standard wrenches while the 7/16" height offers optimal clamping force distribution. Manufactured to ASME B18.2.2 specifications, these external hex nuts solve common assembly challenges by providing consistent performance in automotive, construction, and manufacturing applications where right-hand thread direction and coarse thread spacing facilitate rapid installation and maintenance.

Specification Summary & Compliance

This hex nut maintains precise dimensional tolerances with Class 2B thread fit per UNC standards and complies with ASME B18.2.2 manufacturing specifications. The component meets RoHS 3 (2015/863/EU) compliance for restricted substance control and REACH (EC 1907/2006) regulations for chemical safety. Manufactured from Grade 5 steel with standard inch system measurements, the nut features 1/2"-13 UNC coarse threading with right-hand thread direction and external hex drive configuration measuring 3/4" across flats and 7/16" in height.
