Professional Applications & Engineering Value
This 3/8"-16 UNC flat head screw is engineered to address critical challenges in industrial assembly, where corrosion resistance and precision are paramount. The brass material inherently resists rust and galvanic corrosion, making it ideal for marine, electrical, and plumbing systems exposed to moisture. Its coarse UNC threading and Class 2A fit ensure quick, reliable engagement in soft materials or pre-tapped holes, reducing cross-threading risks. The flat head with an 82° countersink sits flush to prevent snagging and maintain aerodynamic or aesthetic surfaces in machinery, enclosures, and fixtures. With a 50,000 psi tensile strength and Rockwell B50 hardness, it provides robust clamping force without sacrificing ductility, ensuring long-term performance in high-vibration environments.
Specification Summary & Compliance
This screw features a 3/8"-16 UNC coarse thread with Class 2A dimensional accuracy for consistent fit. It is manufactured in compliance with ASME B18.6.3 specifications, ensuring mechanical and dimensional reliability. The product is RoHS 3 (2015/863/EU) compliant under exemption 6(a)-I and REACH (EC 1907/2006) compliant as of the latest assessment, adhering to environmental and safety regulations for industrial use.
