Professional Applications & Engineering Value
This Grade 5 steel hex head screw delivers critical engineering solutions for industrial assemblies requiring high tensile strength and reliable fastening. The UNF fine threading with Class 2A fit prevents loosening in vibrating machinery, while the zinc plated finish protects against corrosion in harsh environments. The external hex drive enables high-torque installation in confined spaces, making it ideal for heavy equipment, structural frameworks, and automotive applications where vibration resistance and long-term reliability are paramount. The fully threaded 3/8"-24 design ensures uniform stress distribution across the entire 2½" length, eliminating weak points in critical connections.
Specification Summary & Compliance
This fastener maintains precision Class 2A thread fit with UNF fine threading (3/8"-24) and right-hand orientation. Manufactured to ASME B18.2.1 specifications and SAE J429 Grade 5 standards, it delivers consistent dimensional accuracy and mechanical properties. The product is fully RoHS 3 (2015/863/EU) compliant and meets industry requirements for hazardous substance restrictions, ensuring environmental responsibility alongside mechanical excellence.
