S-90190A249 Length 1 1/4" 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 strong, permanent threads in sheet metal without requiring pre-tapped holes
• Optimized for 0.025" maximum drilling thickness providing reliable performance in standard sheet metal applications
• Secure Phillips drive engagement ensures positive torque transmission and reduces cam-out during installation
• Full threading along the 1-1/4" length delivers maximum grip and holding power throughout the entire fastener
• Pan head design with standard profile offers a balanced combination of low profile and sufficient bearing surface
• Environmental compliance assurance with RoHS 3 and REACH regulations for global manufacturing applications

Professional Applications & Engineering Value

These No. 10-12 thread forming tapping screws are specifically engineered for sheet metal assembly applications where reliable fastening is critical. The zinc-plated steel construction provides essential corrosion protection while maintaining the high tensile strength needed for structural integrity. The thread forming design (A/AB type) eliminates the need for separate tapping operations, creating precise mating threads that resist vibration loosening. With 12 threads per inch and fully threaded configuration, these screws distribute clamping force evenly, preventing material distortion in thin-gauge metals. The Phillips drive system combined with the pan head design ensures quick installation and a flush finish, making them ideal for HVAC systems, electrical enclosures, and automotive panels where both performance and aesthetics matter.

Specification Summary & Compliance

This tapping screw features precise No. 10-12 thread specifications with 0.19" thread diameter and right-hand threading. The fastener meets industry standards for thread forming applications with pointed tip for easy starting and No. 21 drill bit compatibility (0.159" diameter). Manufacturing and material compliance includes RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring environmental responsibility and suitability for global industrial markets.
