Professional Applications & Engineering Value
These Grade 5 steel hex head screws deliver exceptional engineering value in heavy machinery, structural assemblies, and precision equipment where vibration resistance and long-term reliability are critical. The extra fine 1"-14 UNS thread configuration provides superior clamping force distribution and resistance to loosening under dynamic loads. The zinc plated finish creates a protective barrier against oxidation and chemical exposure in industrial environments, while the fully threaded design ensures maximum engagement in thick materials and complex assemblies. Engineered to ASME B18.2.1 specifications, these industrial fasteners solve common challenges of joint integrity, corrosion management, and maintenance reduction in manufacturing, construction, and equipment maintenance applications.
Specification Summary & Compliance
This hex head screw features precision Class 2A thread fit with 1"-14 extra fine UNS threading and right-hand orientation. Manufactured to ASME B18.2.1 and SAE J429 standards, the fastener maintains dimensional accuracy throughout its 2 1/2" length with 39/64" head height and 1 1/2" head width. Compliance with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations ensures environmental responsibility and workplace safety standards are met for global industrial applications.
