Professional Applications & Engineering Value
Engineered for demanding industrial applications, this Grade 5 hex head screw combines high-strength steel construction with zinc plating to address critical challenges in machinery assembly, structural frameworks, and heavy equipment manufacturing. The 3/8"-24 UNF fine thread configuration delivers superior resistance to vibrational loosening while maintaining clamping force integrity. With Rockwell C25 hardness and fully threaded design, it ensures uniform stress distribution across connected components, preventing joint failure in high-load scenarios. The external hex drive facilitates efficient installation in confined spaces, reducing assembly time while meeting rigorous ASME B18.2.1/SAE J429 specifications for dimensional consistency and performance reliability.
Specification Summary & Compliance
This hex head screw features Class 2A thread fit per UNF standards with precise 3/8"-24 fine threading and 3" full-length threading. Manufactured to ASME B18.2.1 dimensional requirements and SAE J429 Grade 5 mechanical properties, it demonstrates compliance with RoHS 3 (2015/863/EU) environmental regulations. The zinc plated finish provides corrosion protection while maintaining 120,000 psi tensile strength and Rockwell C25 hardness for guaranteed performance in industrial fastening applications.
