S-90190A205 Length 2" Tapping Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with zinc-plated steel construction, extending service life in demanding industrial environments
• Efficient thread-forming design creates permanent, vibration-resistant threads in sheet metal without pre-tapping requirements
• Optimized Phillips drive system (No. 2 size) ensures secure tool engagement and reduces cam-out during installation
• Full 2-inch threading with pointed tip enables rapid penetration and maximum thread engagement in sheet metal assemblies
• Pan head profile with standard rounding provides a finished appearance while maintaining adequate drive torque capacity
• Precision-engineered thread geometry (0.164" diameter, 15 TPI) delivers reliable fastening performance in 0.025" maximum thickness materials
• Environmental compliance assurance meets RoHS 3 and REACH standards for global manufacturing applications

Professional Applications & Engineering Value

These No. 8 x 2" zinc-plated steel tapping screws are engineered specifically for sheet metal applications where reliable fastening and corrosion protection are critical. The thread forming technology (A/AB type) creates strong, strip-resistant threads in ductile materials without generating chips, eliminating cleanup and ensuring consistent clamp load. The fully threaded design with pointed tip facilitates quick starts and reduces installation time, while the Phillips pan head provides a balanced combination of drive efficiency and low-profile appearance. Ideal for HVAC systems, electrical enclosures, and metal fabrication where vibration resistance and environmental durability are essential, these fasteners solve common assembly challenges with precision-engineered performance.

Specification Summary & Compliance

This thread forming sheet metal fastener features precise 0.164" thread diameter with 15 threads per inch and Class 2A thread fit for consistent engagement. Manufactured to standard A/AB tapping screw specifications with right-hand threading and compatible with No. 29 drill bit (0.136" diameter) for proper hole preparation. The product is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, ensuring suitability for global industrial applications and restricted substance requirements.
