S-90935A315 Length 1 1/4" Tapping Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with black-oxide steel coating for extended service life in demanding industrial environments
• Efficient thread-forming design creates permanent, vibration-resistant threads in sheet metal without pre-tapping
• Optimized Phillips No. 3 drive provides secure tool engagement and reduces cam-out during installation
• Full threading along 1-1/4" length ensures maximum holding power and uniform stress distribution
• Precision-engineered pointed tip enables easy starting and smooth penetration into 3/16" pre-drilled holes
• Robust construction handles maximum drilling thickness of 0.025" in sheet metal applications
• Compliance assurance meets RoHS 3 and REACH environmental standards for global industrial use

Professional Applications & Engineering Value

These black-oxide steel sheet metal tapping screws deliver exceptional engineering value through their thread-forming A/AB design that eliminates the need for separate tapping operations. The fully threaded No. 12 configuration with 11 threads per inch creates strong, permanent fastening points in sheet metal assemblies, preventing loosening under vibration. The 0.216" thread diameter combined with the Phillips drive system ensures reliable installation in high-volume production environments. These self-tapping screws are specifically engineered for industrial applications where consistent performance and maximum drilling thickness capability of 0.025" are critical for assembly efficiency and structural integrity.
