Professional Applications & Engineering Value
This 316 stainless steel rounded head screw delivers critical performance advantages in demanding industrial environments where corrosion resistance and mechanical reliability are paramount. The combination of UNC coarse threading and Class 3A precision fit ensures rapid assembly while maintaining vibration resistance in machinery, structural frameworks, and marine equipment. The passivated finish enhances the natural corrosion resistance of 316 stainless steel, making these hex drive screws ideal for chemical processing, offshore applications, and food processing equipment where exposure to moisture and aggressive chemicals is common. With full threading along the entire 1-1/2" length, engineers achieve uniform clamp load distribution, eliminating weak points in critical connections.
Specification Summary & Compliance
This fastener features 3/8"-16 UNC coarse threads with Class 3A thread fit per ASME B18.3 specifications, ensuring precise dimensional accuracy and interchangeability. Manufacturing complies with ASTM F879 standards, while environmental compliance includes RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations. The fully threaded design maintains consistent mechanical properties throughout the entire 1-1/2" length, backed by 70,000 psi tensile strength verification.
