Professional Applications & Engineering Value
Engineered for demanding industrial settings, this Grade 5 zinc-plated steel hex head screw addresses common challenges like vibration-induced loosening and corrosion. The serrated flange eliminates the need for separate washers by providing a built-in locking mechanism that bites into surfaces, ensuring stable connections in machinery, automotive assemblies, and structural frameworks. With its UNF fine thread and Class 2A fit, it delivers precise alignment and reduced cross-threading risks, while the external hex drive facilitates easy installation with standard tools. Ideal for applications requiring high tensile strength and repeated disassembly, it enhances maintenance efficiency and operational safety in construction, manufacturing, and equipment repair.
Specification Summary & Compliance
This fastener adheres to IFI 111/SAE J429 specifications, ensuring dimensional accuracy with Class 2A thread fit and UNF fine thread standards. It is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, supporting environmentally responsible sourcing. The manufacturing process maintains consistent thread diameter of 0.375" and 2" length for reliable performance across industrial applications.
