S-92115A226 Length 3/8" Tapping Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with black zinc-plated steel construction for extended service life in demanding environments.
• Excellent thread-forming capability with Type B design creates strong, reliable threads in sheet metal without pre-tapping.
• Optimized holding power from 18 threads per inch and full threading along the 3/8" length for maximum grip in thin materials.
• Secure and efficient installation with No. 2 Phillips drive that resists cam-out during high-torque applications.
• Precise fit and alignment with standard pan head design that sits flush against surfaces while providing good drive engagement.
• Reduced installation complexity with blunt tip and thread-forming design that eliminates the need for separate tapping operations.
• Compatibility with standard tools using No. 29 drill bits (0.136" diameter) for perfectly sized pilot holes in sheet metal applications.

Professional Applications & Engineering Value

These black zinc-plated steel tapping screws deliver exceptional performance in sheet metal applications where vibration resistance and long-term reliability are critical. The thread forming B type design creates permanent, high-strength threads in ductile metals without generating chips, eliminating contamination concerns in electrical enclosures, HVAC systems, and automotive assemblies. The fully threaded configuration ensures maximum engagement in thin materials, while the Phillips pan head provides a low-profile finish that withstands exposure to industrial environments. With 18 threads per inch and precise 0.164" thread diameter, these screws maintain consistent clamping force even under dynamic loads, making them ideal for manufacturing equipment, metal fabrication, and maintenance operations requiring durable industrial fasteners.

Specification Summary & Compliance

This No. 8 x 3/8" tapping screw features right-hand threads with standard inch system measurements, manufactured to industry standards for thread forming screws. The product maintains precise dimensional accuracy with 0.164" thread diameter and 18 TPI specification, ensuring consistent performance across applications. Compatible with No. 29 drill bits (0.136" diameter) for proper pilot hole preparation. The black zinc-plated surface treatment provides corrosion protection while meeting industry requirements for industrial fasteners used in metalworking applications.
