S-90395A249 Length 1 1/4" Tapping Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with zinc-plated steel construction for extended service life in demanding industrial environments
• Efficient thread forming design creates strong, permanent threads in sheet metal without requiring pre-tapped holes
• Secure No. 2 square drive system provides excellent torque transmission and reduces cam-out during installation
• Fully threaded 1-1/4" length ensures maximum grip and holding power across the entire fastener engagement
• Optimized pan head design offers low-profile installation with improved bearing surface for secure fastening
• Precision compatibility with No. 21 drill bit (0.159" diameter) for accurate hole preparation and maximum drilling thickness of 0.025"
• Regulatory compliance assurance meets RoHS 3 and REACH standards for environmental and safety requirements

Professional Applications & Engineering Value

These No. 10-12 thread forming tapping screws deliver exceptional value in sheet metal applications where reliable fastening is critical. The zinc-plated steel construction provides essential corrosion protection while maintaining high tensile strength. The A/AB thread forming design eliminates the need for separate tapping operations, reducing installation time and labor costs. With 12 threads per inch and fully threaded construction, these screws distribute clamping force evenly, preventing material distortion in thin-gauge metals. The pan head with No. 2 square drive ensures secure tool engagement, minimizing stripping and improving installation efficiency in high-volume production environments.

Specification Summary & Compliance

These thread forming sheet metal screws feature precise 0.19" thread diameter with 12 threads per inch and right-hand thread direction. The 1-1/4" fully threaded design maintains consistent engagement throughout the fastener length. Manufactured to industry standards for A/AB tapping screw types, these fasteners ensure reliable performance in sheet metal applications. Compliance with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations guarantees environmental safety and regulatory acceptance for industrial use across various markets.
