S-90410A144 6-32 x 1/4" Tapping Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with 410 stainless steel construction for long-lasting performance in demanding industrial environments.
• Efficient thread cutting action with Type F tapping screw design creates precise threads in brass, cast iron, and sheet metal without pre-tapping.
• Reliable fastening power through UNC coarse threads that provide excellent holding strength and reduced cross-threading risk.
• Optimized installation control with Phillips No. 2 drive and pan head design ensuring secure tool engagement and consistent torque application.
• Versatile material compatibility for multiple applications including sheet metal fabrication, brass components, and cast iron assemblies.
• Full thread engagement along the entire 1/4" length delivers maximum grip strength and uniform load distribution.
• Environmental compliance assurance meeting RoHS 3 and REACH standards for safe, sustainable manufacturing practices.

Professional Applications & Engineering Value

These 6-32 UNC coarse thread tapping screws deliver exceptional engineering value through their thread cutting technology and 410 stainless steel composition. The Type F tapping screw design with blunt tip and coarse UNC threads enables direct installation into sheet metal, brass, and cast iron without pilot holes, significantly reducing assembly time and labor costs. The Phillips No. 2 drive combined with the pan head profile provides excellent torque transmission while preventing cam-out during high-speed installation. This combination of precision threading and durable material solves critical industrial challenges by eliminating strip-out issues, maintaining thread integrity under vibration, and ensuring reliable performance in metal fabrication, automotive components, and electrical enclosures where right-hand threaded fasteners are essential.
