S-90190A323 Length 3" Tapping Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with zinc-plated steel construction for long-lasting performance in harsh industrial environments
• Effortless installation thanks to pointed tip design and thread forming technology that eliminates pre-tapping requirements
• Maximum driving efficiency with No. 3 Phillips drive that prevents cam-out and ensures secure fastening
• Complete thread engagement through full threading along the 3" length for superior holding power in sheet metal
• Optimized head design with standard pan profile providing a balanced bearing surface without sharp edges
• Reliable thread formation using A/AB type thread forming screws that create strong, permanent connections
• Regulatory compliance assurance meeting RoHS 3 and REACH standards for safe industrial usage

Professional Applications & Engineering Value

These No. 14 zinc-plated steel tapping screws deliver exceptional engineering value for sheet metal applications where vibration resistance and pull-out strength are critical. The thread forming design creates precise mating threads in parent material without generating chips, eliminating contamination risks in sensitive assemblies. The Phillips drive system ensures consistent torque application while the fully threaded shank provides uniform stress distribution across the entire fastener length. Particularly valuable in HVAC systems, electrical enclosures, and metal fabrication, these industrial screws maintain integrity under thermal cycling and mechanical stress. The combination of 0.242" thread diameter and 10 threads per inch delivers optimal balance between installation speed and joint strength.
