Professional Applications & Engineering Value

This 3/8"-16 UNC brass flat head screw addresses critical engineering challenges in industrial applications where corrosion resistance and precise fit are paramount. The Class 3A thread fit ensures minimal play and superior vibration resistance in machinery, electrical enclosures, and marine equipment. The brass material provides excellent conductivity while resisting galvanic corrosion, making it ideal for electrical components and plumbing systems. With its 82° countersink angle and hex drive, installers achieve flush mounting without protrusions, maintaining aerodynamic and aesthetic surfaces. The combination of 50,000 psi tensile strength and full threading delivers reliable performance in high-stress assemblies where load distribution and thread engagement are critical.
