Professional Applications & Engineering Value
Engineered for demanding industrial settings, these 3/8"-16 UNC flat head screws in 316 stainless steel address critical fastening challenges where corrosion resistance and structural integrity are paramount. The passivated finish enhances durability against chemicals and moisture, making them ideal for marine, chemical processing, and food-grade equipment. With a Class 3A thread fit and coarse UNC threading, they provide superior resistance to loosening under vibration, common in machinery and automotive assemblies. The 82° countersink angle ensures a flush fit, eliminating protrusions in precision applications like aerospace components or enclosures. These screws deliver reliable performance in heavy-duty industrial fastening, reducing maintenance cycles and enhancing operational safety.
Specification Summary & Compliance
This flat head screw features a 3/8"-16 UNC thread with Class 3A precision tolerance, ensuring tight fit and minimal backlash. Manufacturing adheres to ASME B18.3 specifications for dimensional accuracy, including head diameter (0.781") and length (1/2"). The product is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, guaranteeing environmental safety and restricted substance-free composition for global industrial use.
