S-92115A217 Length 1/4" Tapping Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with black zinc-plated steel construction for extended service life in demanding environments
• Efficient thread forming action creates strong, permanent threads in sheet metal without pre-tapped holes
• Optimized drive engagement with Phillips No. 2 head prevents cam-out and ensures secure installation
• Complete thread coverage along the 1/4" length provides maximum holding power and vibration resistance
• Precision compatibility with standard No. 32 drill bits (0.116" diameter) for streamlined installation processes
• Enhanced material displacement with blunt tip design reduces cracking in thin sheet metal applications
• Regulatory compliance assurance with RoHS 3 certification for environmentally responsible manufacturing

Professional Applications & Engineering Value

This No. 6-20 thread forming screw delivers exceptional performance in sheet metal assembly applications where traditional fastening methods fall short. The black zinc-plated steel construction provides a durable barrier against corrosion, while the Type B thread forming design creates precise mating threads through material displacement rather than cutting. This eliminates chip formation and ensures tight, vibration-resistant connections in electrical enclosures, HVAC systems, and automotive panels. The fully threaded blunt tip configuration minimizes stress concentration points, reducing the risk of material fatigue in thin-gauge metals. With its Phillips pan head and standardized No. 32 drill bit compatibility, this fastener streamlines production workflows while maintaining consistent clamping force across repetitive assembly operations.

Specification Summary & Compliance

This thread forming Type B tapping screw features precise 0.138" thread diameter with 20 threads per inch in right-hand orientation, manufactured to standard inch system tolerances. The fully threaded 1/4" length and rounded pan head profile (0.27" diameter) ensure consistent performance across sheet metal applications. Compliant with RoHS 3 (2015/863/EU) regulations, this fastener meets international environmental standards while delivering reliable mechanical performance in industrial fastening scenarios requiring corrosion resistance and secure thread engagement.
