S-92365A428 Length 2 1/4" 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 installation with self-drilling No. 2 tip that eliminates pre-drilling requirements in steel and sheet metal applications
• Enhanced material integrity through thread forming technology that creates stronger, more secure threads without chip removal
• Optimal flush mounting with standard flat head profile and 82° countersink angle for smooth, professional finishes
• Maximum holding power with fully threaded design and 20 threads per inch for superior fastening strength
• Reliable drive engagement with No. 2 Phillips drive that prevents cam-out during high-torque installation
• Versatile material compatibility capable of drilling through 0.09" thick steel and sheet metal with consistent performance

Professional Applications & Engineering Value

These No. 6 zinc-plated steel tapping screws deliver exceptional engineering value in steel and sheet metal applications where traditional fastening methods fall short. The thread forming technology creates permanent, high-strength threads by displacing material rather than cutting it, eliminating chip-related contamination in sensitive assemblies. The self-drilling tip with 9/64" drill length streamlines installation workflows by combining drilling and tapping operations into a single step, significantly reducing labor time and equipment requirements. The zinc-plated finish provides reliable corrosion protection in industrial environments, while the Phillips flat head design ensures flush mounting for safety and aesthetic requirements. These BSD tapping screws are engineered to maintain consistent performance in high-vibration applications common in construction, HVAC, and metal fabrication industries.

Specification Summary & Compliance

These thread forming screws feature precision No. 6 screw size with 0.138" thread diameter and 20 threads per inch in right-hand orientation. The flat head measures 0.262" in diameter with standard profile and 82° countersink angle. Manufactured to BSD tapping screw standards with fully threaded 2-1/4" length and No. 2 Phillips drive for consistent installation performance. The zinc-plated steel construction meets industry standards for corrosion resistance and mechanical properties suitable for industrial and construction applications requiring reliable fastening solutions in steel and sheet metal substrates up to 0.09" thickness.
