S-90190A316 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
• Exceptional holding power through thread forming technology that creates strong, permanent threads in sheet metal without chip removal
• Efficient installation with Phillips No. 3 drive that provides reliable torque transfer and reduces cam-out during assembly
• Maximum thread engagement from fully threaded design ensuring consistent clamping force along the entire fastener length
• Optimized for sheet metal applications with pointed tip for easy starting and precise alignment in 0.025" maximum thickness materials
• Regulatory compliance assurance meeting RoHS 3 and REACH standards for safe use in global industrial markets
• Versatile pan head design offering low-profile installation with standard rounded profile for various sheet metal assemblies

Professional Applications & Engineering Value

These No. 14 tapping screws are specifically engineered for sheet metal applications where reliable fastening is critical. The zinc-plated steel construction provides essential corrosion protection in industrial environments, while the thread forming technology eliminates the need for pre-tapped holes, reducing installation time and labor costs. The A/AB tapping screw type with fully threaded design ensures maximum pull-out resistance in thin materials up to 0.025" thickness. The Phillips pan head with No. 3 drive size offers efficient power transfer during installation, minimizing tool slippage and damage to the fastener head. These characteristics make them ideal for metalworking, HVAC systems, electrical enclosures, and automotive assemblies where vibration resistance and long-term reliability are paramount.

Specification Summary & Compliance

These tapping screws feature precise dimensional specifications including 0.242" thread diameter, 10 threads per inch, and 1-1/4" length with Class 2A thread tolerances. The thread forming design conforms to standard A/AB tapping screw specifications, requiring a 5.5 mm (0.2165") drill bit for proper installation. Manufacturing and material compliance includes RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring environmental safety and industrial suitability for global supply chains.
