Professional Applications & Engineering Value
These 5/16"-18 UNC brass flat head screws deliver exceptional performance in demanding industrial environments where corrosion resistance and mechanical integrity are paramount. The Rockwell B50 hardness rating combined with 50,000 psi tensile strength ensures reliable fastening in vibration-prone applications while maintaining excellent machinability. The standard 82° countersink angle and Phillips No. 4 drive work in harmony to provide flush mounting capabilities with efficient installation in electrical enclosures, marine hardware, and plumbing systems. The fully threaded coarse spacing design offers superior pull-out resistance in softer materials, making these brass flat head screws ideal for applications requiring repeated disassembly and reassembly without compromising thread integrity.
Specification Summary & Compliance
Manufactured to exacting ASME B18.6.3 specifications with Class 2A thread fit tolerance for precision engagement. The UNC coarse thread with right-hand direction follows industry standards for compatibility with existing hardware. Compliant with RoHS 3 (2015/863/EU) under exemption 6(a)-I for lead as an alloying element and REACH (EC 1907/2006) regulations, ensuring environmental responsibility while maintaining optimal brass alloy performance characteristics for industrial fastening applications.
