S-90048A079 Length 3/8" Tapping Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with zinc-plated steel construction for extended service life in demanding industrial environments
• Efficient thread forming technology creates precise mating threads without chips, eliminating secondary tapping operations
• Optimal flush mounting with standard flat head profile and 82° countersink angle for smooth surface finishes
• Maximum holding power through fully threaded design and 32 threads per inch configuration
• Quick installation compatibility with standard No. 48 drill bits (0.076" diameter) for streamlined assembly processes
• Reliable drive engagement with No. 1 Phillips drive size preventing cam-out during high-torque applications
• Environmental compliance assurance meeting RoHS 3 standards for global manufacturing requirements

Professional Applications & Engineering Value

These No. 2 Phillips flat head tapping screws deliver exceptional performance in sheet metal assembly applications where vibration resistance and secure fastening are critical. The thread forming design eliminates the need for pre-tapped holes while creating stronger thread engagement through material displacement rather than removal. Manufactured from zinc-plated steel, these screws provide reliable corrosion protection for HVAC systems, electrical enclosures, and automotive components. The 82° countersink angle ensures proper seating in standard sheet metal applications up to 0.025" thickness, while the fully threaded configuration maintains consistent clamping force across the entire engagement length. Engineered for production efficiency, these A/AB tapping screws reduce installation time and improve assembly reliability in high-volume manufacturing environments.

Specification Summary & Compliance

These tapping screws feature precision 0.086" thread diameter with 32 threads per inch in right-hand orientation, conforming to standard thread forming specifications. The flat head profile with standard dimensions (0.162" head diameter, 0.051" head height) ensures proper countersinking. Manufacturing complies with RoHS 3 (2015/863/EU) environmental regulations, making them suitable for global industrial applications requiring restricted substance compliance. The screws are engineered for use with No. 48 drill bits (0.076" diameter) and are optimized for sheet metal applications with maximum drilling thickness of 0.025".
