S-90086A613 6-32 x 1" ASME B18.6.3, SAE J933 Tapping Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with zinc-plated steel construction for extended service life in demanding industrial environments
• Effortless installation with Type F thread cutting design that eliminates the need for pre-tapped holes in aluminum, brass, cast iron, and sheet metal
• Secure fastening performance through UNC coarse threading that provides excellent holding power in various materials
• Optimized drive efficiency with No. 2 Phillips drive that ensures reliable torque transmission and reduces cam-out risks
• Flush mounting capability with standard 82° flat head profile that sits perfectly in countersunk applications
• Full-length threading for maximum grip along the entire 1" length, enhancing pull-out resistance in assembled components
• Regulatory compliance assurance meeting both ASME B18.6.3 engineering standards and RoHS 3 environmental directives

Professional Applications & Engineering Value

These 6-32 thread cutting screws deliver exceptional engineering value by solving common fastening challenges in metalworking and manufacturing applications. The zinc-plated steel construction provides essential corrosion protection while maintaining high tensile strength for durable assemblies. The Type F tapping screw design with UNC coarse threads creates precise mating threads in aluminum, brass, cast iron, and sheet metal substrates without requiring pre-tapped holes, significantly reducing installation time and labor costs. The combination of No. 2 Phillips drive and 82° countersink angle ensures secure, flush-mounted fastenings in tight-clearance applications common in electrical enclosures, machinery panels, and structural fabrications. This comprehensive solution addresses the critical need for reliable, self-tapping fasteners that maintain integrity under vibration and load stress.

Specification Summary & Compliance
