S-94058A105 Length 1/2" Tapping Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with zinc-plated 410 stainless steel construction, ideal for harsh industrial environments
• Efficient thread-forming installation using BSD technology eliminates the need for pre-tapping, reducing assembly time and labor costs
• Reliable sealing performance with integrated stainless steel/rubber washer that prevents leakage and protects against moisture ingress
• Enhanced drilling capability with specialized tip that penetrates up to 0.098" thickness in stainless steel and sheet metal without pilot holes
• Optimal torque transmission through external hex drive design, preventing cam-out and ensuring secure fastening in high-vibration applications
• Full-thread engagement along the entire 1/2" length provides maximum pull-out strength and vibration resistance in thin materials
• Precision dimensional consistency with No. 8-18 thread specifications ensures reliable performance and interchangeability

Professional Applications & Engineering Value

These zinc-plated 410 stainless steel tapping screws deliver exceptional value in demanding stainless steel and sheet metal applications where corrosion resistance and sealing integrity are critical. The thread-forming BSD design creates stronger, more durable threads in parent material compared to cutting screws, eliminating chip formation and potential contamination in sensitive assemblies. The integrated stainless steel/rubber sealing washer provides reliable environmental protection against moisture, dust, and chemical exposure, making these fully-threaded screws ideal for HVAC systems, electrical enclosures, and outdoor equipment. The combination of drilling tip technology and external hex drive streamlines installation in tight spaces while maintaining high clamp loads, significantly reducing assembly time and improving production efficiency in industrial manufacturing environments.
