S-92365A479 Length 2 1/2" Tapping Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with zinc-plated steel construction for extended service life in demanding environments
• Efficient self-drilling capability with specialized No. 3 drill tip that eliminates pre-drilling requirements
• Maximum material penetration with ability to drill through up to 0.22" thickness in steel and sheet metal
• Enhanced holding power through thread forming technology that creates stronger, more secure connections
• Clean, flush installation with standard 82° countersink angle and flat head design for smooth surface finishes
• Reliable driving performance with Phillips No. 3 drive that provides excellent torque transfer and reduces cam-out
• Full-thread engagement along the entire 2 1/2" length ensures maximum pull-out resistance in critical applications

Professional Applications & Engineering Value

These zinc-plated steel tapping screws deliver exceptional performance in steel and sheet metal applications where durability and installation efficiency are paramount. The thread forming BSD technology creates stronger fastening points by displacing material rather than removing it, resulting in superior resistance to vibration loosening. The integrated No. 3 drilling tip eliminates the need for separate drilling operations, significantly reducing installation time and labor costs in industrial assembly lines, construction projects, and metal fabrication. The fully threaded design with 14 TPI provides consistent holding strength throughout the entire fastener length, while the 82° countersink angle ensures proper seating in standard applications. These industrial fasteners are engineered to withstand the rigors of demanding environments while maintaining their structural integrity.

Specification Summary & Compliance

These 1/4" tapping screws feature precision right-hand threads with 14 threads per inch and comply with BSD tapping screw standards. The manufacturing process ensures consistent dimensional accuracy with proper thread form geometry for reliable performance. The zinc-plated steel construction provides corrosion protection while maintaining the mechanical strength required for industrial applications. These fasteners are manufactured in compliance with industry standards for metalworking screws and are suitable for use in various steel and sheet metal joining applications where durability and installation efficiency are critical requirements.
