Professional Applications & Engineering Value
This 3/8"-16 UNC hex head screw is engineered to solve critical challenges in demanding industrial settings. The 316 stainless steel material provides exceptional resistance to chlorides and acidic environments, preventing failure in chemical processing, marine, and offshore applications. The combination of 70,000 PSI tensile strength and Rockwell B70 hardness ensures these fully threaded fasteners maintain clamp load under extreme vibration and thermal cycling. The coarse thread spacing and Class 2A thread fit enable rapid assembly in structural steel, heavy machinery, and transportation equipment while minimizing the risk of thread stripping. These industrial hex screws deliver long-term reliability where corrosion and mechanical stress would compromise inferior fasteners.
Specification Summary & Compliance
This hex head screw features precision 3/8"-16 UNC coarse threads with Class 2A dimensional tolerance for consistent fit. Manufactured to ASME B18.2.1 specifications, it ensures interchangeability and performance reliability. The product is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, making it suitable for global industrial supply chains with strict material restrictions.
