Professional Applications & Engineering Value

These brass flat head slotted screws deliver exceptional engineering value through their specialized material properties and precision manufacturing. The 1/2"-13 UNC coarse threading provides superior holding power in soft materials and faster installation times, while the fully threaded design ensures maximum engagement throughout the entire fastener length. The 82° countersink angle creates a clean, flush finish that eliminates protrusions in machinery and equipment assemblies. Particularly valuable in electrical applications where brass's natural conductivity and non-sparking properties are critical, these screws also excel in marine environments and plumbing systems where corrosion resistance is paramount. The combination of 50,000 psi tensile strength and Rockwell B50 hardness ensures these fasteners maintain integrity under vibration and thermal cycling, solving common failure points in industrial equipment.

Specification Summary & Compliance

These precision-engineered screws feature Class 2A thread fit per UNC standards, ensuring consistent engagement and reliable performance. Manufacturing complies with ASME B18.6.3 specifications for dimensional accuracy and quality assurance. The screws are fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, making them suitable for use in regulated industries and international markets.
