Professional Applications & Engineering Value
These 10-32 UNF flat head Phillips screws deliver critical engineering solutions where corrosion resistance and structural integrity are paramount. The passivated 18-8 stainless steel construction withstands corrosive environments while maintaining Rockwell B80 hardness for durability. The UNF fine threading and Class 2A fit ensure precise engagement in tapped holes, reducing the risk of cross-threading in precision assemblies. With full threading across the 2" length, these screws provide maximum load distribution in applications from machinery manufacturing to electronic enclosures. The 82° countersink angle and flat head design create flush surfaces critical for aerodynamic and safety applications, while the Phillips drive offers familiar, efficient installation in high-volume production environments.
Specification Summary & Compliance
Manufactured to exact ASME B18.6.3 specifications with Class 2A thread fit tolerance for consistent performance. Features UNF (Unified National Fine) 10-32 threading with standard spacing and right-hand thread direction. Full compliance with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations. The passivated surface treatment enhances corrosion resistance while maintaining the material's inherent 80,000 psi tensile strength and Rockwell B80 hardness properties.
