Professional Applications & Engineering Value
This Grade 5 hex head screw delivers critical engineering solutions for industrial applications where vibration resistance and structural integrity are paramount. The 1"-14 extra fine thread configuration provides superior holding power in thin-section materials and precision assemblies, while the zinc plated steel construction offers reliable corrosion protection in manufacturing environments. The partially threaded design concentrates strength at the engagement point, reducing stress concentration and preventing joint failure. Ideal for heavy machinery, structural steel connections, and equipment manufacturing, this industrial fastener combines high tensile strength with precise Class 2A thread fit to ensure consistent performance in critical applications where safety and durability cannot be compromised.
Specification Summary & Compliance
Manufactured to exacting ASME B18.2.1 and SAE J429 specifications, this hex head screw features precision Class 2A thread fit with 1"-14 extra fine thread spacing in the UNS system. The fastener maintains dimensional accuracy with a 6" length, 1 1/2" head width, and 39/64" head height. Compliance with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations ensures environmental responsibility and workplace safety standards are met for industrial applications worldwide.
