S-90048A204 Length 1 3/4" Tapping Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with zinc-plated steel construction, extending service life in demanding industrial environments
• Efficient thread-forming installation creates strong, permanent threads in sheet metal without requiring pre-tapped holes
• Optimal flush mounting with standard flat head profile and 82° countersink angle for smooth surface finishes
• Enhanced driving stability through Phillips No. 2 drive system, reducing cam-out and tool slippage during installation
• Maximum material engagement with fully threaded design and 15 TPI configuration for superior holding power
• Precision compatibility with No. 29 drill bits and 0.025" maximum drilling thickness for consistent performance
• Regulatory compliance assurance meeting RoHS 3 and REACH standards for global industrial applications

Professional Applications & Engineering Value

These No. 8 zinc-plated steel tapping screws deliver exceptional engineering value in sheet metal applications where reliable fastening is critical. The thread forming technology eliminates the need for separate tapping operations, significantly reducing assembly time and labor costs while creating stronger, more vibration-resistant connections. The A/AB tapping screw type with right-hand threading and pointed tip ensures smooth penetration and optimal thread engagement in materials up to 0.025" thickness. The combination of zinc-plated steel material and Phillips flat head design provides both corrosion protection and flush mounting capabilities, making these industrial tapping screws ideal for HVAC systems, electronic enclosures, automotive components, and machinery where surface aesthetics and long-term durability are paramount.
