Professional Applications & Engineering Value
These 6-32 zinc-plated steel tapping screws deliver exceptional engineering value in metal fabrication and assembly applications. The thread-cutting design eliminates the need for pre-tapped holes, significantly reducing installation time and labor costs while providing secure fastening in aluminum, brass, cast iron, and sheet metal components. The Phillips flat head configuration ensures flush mounting for clean, professional finishes in visible applications, while the zinc-plated steel construction provides reliable corrosion protection in industrial environments. Engineered with UNC coarse threads and full threading, these screws offer superior resistance to vibration loosening and maintain clamping force under dynamic loads, making them ideal for machinery, enclosures, and structural assemblies where reliability is critical.
Specification Summary & Compliance
These tapping screws feature 6-32 UNC coarse threads with Class 2A tolerance for consistent fit and performance. Manufactured to ASME B18.6.3 specifications (SAE J933) ensuring dimensional accuracy and mechanical properties. The Type F thread-cutting design is optimized for use with No. 31 drill bit (0.12" diameter) and features standard 82° countersink angle. Fully compliant with RoHS 3 (2015/863/EU) regulations for environmental safety and restricted substance control.
