S-90048A251 Length 1 1/2" Tapping Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with zinc-plated steel construction for extended service life in industrial environments
• Efficient thread forming capability creates strong, permanent threads in sheet metal without requiring pre-tapped holes
• Optimized Phillips No. 2 drive ensures secure tool engagement and reduces cam-out during installation
• Full threading along 1-1/2" length provides maximum grip and holding power throughout the entire fastener
• Precision flat head design with 82° countersink angle sits flush with surfaces for clean, professional finishes
• Reliable performance in thin materials with 0.025" maximum drilling thickness capability
• Environmental compliance assurance meets RoHS 3 and REACH standards for sustainable manufacturing

Professional Applications & Engineering Value

These No. 10 zinc-plated steel tapping screws deliver exceptional value in sheet metal fabrication and assembly applications. The thread forming Type A/AB design eliminates the need for separate tapping operations, significantly reducing installation time and labor costs. The Phillips flat head configuration provides a clean, flush finish that's ideal for applications where protruding fasteners are unacceptable. Engineered for 0.025" maximum drilling thickness, these screws maintain structural integrity in thin-gauge materials without causing deformation or stress concentrations. The combination of zinc plating and fully threaded shank ensures reliable performance in demanding industrial environments where vibration resistance and long-term durability are critical requirements.

Specification Summary & Compliance

These Type A/AB thread forming screws feature precise No. 10 thread diameter with 12 threads per inch and standard flat head profile measuring 0.362" in diameter. The 1-1/2" fully threaded length and pointed tip facilitate easy starting and consistent installation. Manufactured to industry standards for sheet metal applications with recommended No. 21 drill bit (0.159" diameter) compatibility. Fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, ensuring safe use across various industrial sectors.
