S-92365A447 Length 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 tip that eliminates pre-drilling requirements, saving labor time and costs
• Exceptional holding power through thread forming design that creates strong, permanent threads in steel and sheet metal
• Optimized drive performance with Phillips No. 2 drive that provides reliable torque transfer and reduces cam-out
• Perfect flush mounting with standard flat head profile and 82° countersink angle for clean, professional finishes
• Maximum thread engagement with full threading along the 4" length for superior load distribution
• Versatile material compatibility specifically engineered for steel and sheet metal applications up to 0.1" thickness

Professional Applications & Engineering Value

These No. 8 zinc-plated steel tapping screws deliver exceptional engineering value in industrial fastening applications where durability and efficiency are paramount. The thread forming design creates permanent, high-strength connections in steel and sheet metal without requiring pre-tapped holes, significantly reducing assembly time and labor costs. The integrated drilling tip with No. 2 point specification penetrates materials up to 0.1" thick, eliminating separate drilling operations. The zinc-plated finish provides reliable corrosion protection, while the Phillips drive system ensures consistent torque application during high-volume production runs. These BSD tapping screws are particularly valuable in metal fabrication, HVAC installations, and electrical enclosure assembly where strong, permanent fastening is critical for structural integrity.

Specification Summary & Compliance

These tapping screws feature precise 0.164" thread diameter with 18 TPI right-hand threading and fully threaded design for maximum engagement. Manufactured to BSD standards with thread forming technology, they ensure reliable performance in demanding applications. The flat head configuration with 82° countersink angle provides proper seating in standard applications. These industrial fasteners comply with RoHS and REACH environmental standards and are manufactured according to ASME quality specifications for consistent dimensional accuracy and performance reliability.
