S-90048A207 Length 2 1/2" 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 strong, permanent threads in sheet metal without pre-tapping, reducing installation time and labor.
• Flush, secure seating with a standard flat head and 82° countersink angle for a smooth surface finish and vibration resistance.
• Reliable drive engagement using a No. 2 Phillips drive, minimizing cam-out and ensuring consistent torque application.
• Full-length threading and pointed tip for rapid penetration and maximum thread engagement in materials up to 0.025" thick.
• Precise compatibility with No. 29 drill bits (0.136" diameter), ensuring accurate pilot holes and optimal fastener performance.
• Compliance with global regulations including RoHS 3 and REACH, ensuring safe use and environmental responsibility.

Professional Applications & Engineering Value

This No. 8-15 thread forming screw is specifically engineered for sheet metal applications, where traditional fasteners may strip or loosen under stress. Made from zinc-plated steel, it resists rust and corrosion in humid or outdoor settings, maintaining clamp load over time. The A/AB tapping screw type with a right-hand thread displaces material to form durable, high-strength threads without chips, eliminating the need for tapped holes and speeding up assembly lines. The Phillips flat head design sits flush to prevent snagging and improve aesthetics in HVAC, electronics enclosures, and automotive panels. Its fully threaded shank and pointed tip ensure quick starts and full grip length, reducing the risk of joint failure in thin-gauge metals.

Specification Summary & Compliance

This screw adheres to standard inch measurements with a thread diameter of 0.164" and approximately 15 threads per inch (TPI). It is designed for use with a No. 29 drill bit (0.136" diameter) and features an 82° countersink angle for proper head seating. The product is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring it meets stringent industrial safety and environmental standards.
