Professional Applications & Engineering Value
This 3/8"-16 UNC hex head screw is engineered to solve critical challenges in industrial assembly and construction. Manufactured from 316 Stainless Steel, it offers exceptional resistance to corrosion from chemicals, saltwater, and extreme weather, making it ideal for marine, chemical processing, and outdoor infrastructure. The coarse thread and Class 2A thread fit provide rapid installation and reliable holding power in wood, metal, and composite materials, reducing assembly time and preventing cross-threading. The partially threaded design ensures that the unthreaded shank bears the load directly, minimizing stress on the threaded portion and preventing joint loosening under vibration. This combination of high tensile strength and corrosion resistance delivers long-term reliability for structural frameworks, machinery, and heavy equipment.
Specification Summary & Compliance
This hex head screw features a 3/8"-16 UNC thread with a Class 2A fit for standard tolerance and easy assembly. It is precision-manufactured in accordance with ASME B18.2.1 specifications and is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, ensuring safety and sustainability in industrial use.
