S-90198A742 Length 1 1/2" Tapping Screws

Key Features & Benefits at a Glance

• Exceptional corrosion resistance with 316 stainless steel construction, ideal for harsh environments and outdoor applications.
• Superior thread-forming capability creates strong, permanent threads in sheet metal without pre-tapping, reducing installation time and tooling.
• Flush and secure fastening with a standard 82° flat head and Phillips No. 3 drive, providing a clean finish and reliable torque transfer.
• Optimized for sheet metal with a pointed tip and fully threaded No. 14 shank, ensuring excellent grip and pull-out resistance in materials up to 0.025" thick.
• Guaranteed material safety and environmental responsibility with full compliance to RoHS 3 and REACH regulations.
• Precise dimensional accuracy with a 0.242" thread diameter and 10 threads per inch, ensuring consistent performance and interchangeability.
• Versatile industrial application due to its right-hand threading and round shank, making it a reliable choice for various assembly lines.

Professional Applications & Engineering Value

These No. 14 Phillips flat head tapping screws are engineered to solve common fastening challenges in sheet metal fabrication. The 316 stainless steel material offers superior resistance to corrosion from chemicals, saltwater, and extreme weather, which is critical for HVAC, marine, and food processing equipment. The thread-forming (Type A/AB) design eliminates the need for a separate tapping operation, as the screw cold-forms its own mating thread, reducing labor costs and preventing stripping in thin-gauge metals. The flat head with an 82° countersink sits flush with the surface, minimizing snagging and improving aerodynamic or aesthetic profiles. This combination of corrosion-resistant material and efficient thread-forming technology ensures long-term structural integrity and reduces maintenance cycles in demanding industrial settings.

Specification Summary & Compliance

This screw conforms to standard inch dimensions with a No. 14 screw size, 1-1/2" length, and fully threaded profile. The thread is right-hand with a diameter of 0.242" and approximately 10 threads per inch. The flat head features a standard profile with an 82° countersink angle. Manufacturing and material compliance are assured, meeting RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) standards, confirming the absence of restricted hazardous substances for safe use in global markets.
