S-90198A288 Length 3" Tapping Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with 316 Stainless Steel construction, ideal for harsh industrial environments and outdoor applications.
• Efficient thread forming design creates strong, permanent threads in sheet metal without pre-tapping, reducing installation time and tooling.
• Optimized for sheet metal with a pointed tip and specific drill bit size (No. 29 / 0.136"), ensuring clean entry and secure fastening up to 0.025" thickness.
• Reliable Phillips drive (No. 2) provides common tool compatibility and controlled torque application, minimizing cam-out risks.
• Standard 82° flat head sits flush with surfaces for a smooth finish and reduced snagging in assembled products.
• Full threading along the 3" length offers maximum grip and adjustment flexibility in various material thicknesses.
• Compliant with RoHS 3 and REACH regulations, ensuring environmental safety and meeting global industrial standards for hazardous substances.

Professional Applications & Engineering Value

These thread forming tapping screws are precision-engineered to address common challenges in sheet metal fabrication, such as strip-out and loose fasteners. The 316 Stainless Steel material provides exceptional resistance to chemicals, saltwater, and extreme temperatures, crucial for marine, chemical processing, and food industry equipment. The Phillips flat head design ensures a secure, flush fit that maintains aerodynamic and aesthetic surfaces in enclosures, panels, and assemblies. By eliminating the need for separate tapping operations, these screws reduce labor costs and streamline production lines, while the specified No. 29 drill bit and 82° countersink ensure precise, repeatable installations every time.

Specification Summary & Compliance

This product adheres to standard inch measurements with a No. 8 screw size, 0.164" thread diameter, and 15 threads per inch. The flat head features a standard profile with a diameter of 0.312" and height of 0.1". It is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, confirming the absence of restricted hazardous substances for safe use in industrial and commercial applications worldwide.
