S-92365A443 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 industrial environments
• Efficient installation with Phillips drive and No. 2 drill tip that eliminates pre-drilling in steel and sheet metal up to 0.1" thickness
• Vibration-resistant fastening through thread forming technology that creates stronger, more secure connections without chip removal
• Clean flush finishing with standard flat head profile and 82° countersink angle for smooth surface applications
• Full-thread engagement along the entire 2-1/2" length provides maximum holding power and pull-out resistance
• Precision threading with 0.164" diameter and 18 TPI ensures consistent performance and reliable fastening in metal substrates
• BSD screw design offers optimized performance for steel and sheet metal applications with proven industry acceptance

Professional Applications & Engineering Value

These No. 8 zinc-plated steel tapping screws deliver exceptional value in metal fabrication and construction applications where vibration resistance and corrosion protection are critical. The thread forming technology eliminates the need for tapping operations while creating stronger fastening points through material displacement rather than chip removal. The specialized drilling tip penetrates up to 0.1" thickness in steel and sheet metal without pre-drilling, significantly reducing installation time and labor costs. The fully threaded design ensures maximum thread engagement throughout the fastened materials, while the 82° countersink angle and flat head profile provide clean, flush finishes in visible applications. These BSD screws are engineered to maintain clamping force under dynamic loads, making them ideal for HVAC systems, metal framing, electrical enclosures, and industrial equipment assembly.

Specification Summary & Compliance

These industrial fasteners feature precision 0.164" thread diameter with 18 TPI and comply with standard inch system measurements. The thread forming design follows established BSD tapping screw specifications, while the zinc-plated steel construction provides corrosion resistance suitable for industrial environments. The screws maintain dimensional accuracy with standard flat head profile and are manufactured to meet industry standards for metal fastening applications, ensuring reliable performance and compatibility with standard installation tools and procedures.
