S-90822A149 Length 5/8" Tapping Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with 410 Stainless Steel construction, ideal for harsh industrial environments and outdoor applications.
• Efficient self-drilling capability with a No. 2 drill tip that eliminates the need for pre-drilling, saving time and labor costs in steel and sheet metal assembly.
• Enhanced holding power and vibration resistance thanks to the integrated flange design, providing a larger bearing surface and preventing loosening.
• High-torque installation enabled by the external hex head, allowing for secure and fast driving with standard tools.
• Reliable thread forming action (BSD type) creates strong, clean threads in ductile materials, reducing the risk of stripping and ensuring a tight fit.
• Full threading along the 5/8" length maximizes grip and load distribution across the entire fastened joint.
• Compliance with major environmental regulations including RoHS 3 and REACH, ensuring safety and suitability for global industrial supply chains.

Professional Applications & Engineering Value

This No. 6-20 self-drilling tapping screw is engineered to solve common fastening challenges in steel, stainless steel, and sheet metal assemblies. Its 410 Stainless Steel material offers excellent strength and moderate corrosion resistance, making it suitable for construction, HVAC, and metal fabrication where durability is critical. The thread forming (BSD) design cold-forms mating threads without generating chips, which minimizes debris and enhances joint integrity. The No. 2 drill tip efficiently penetrates up to 0.09" thickness, streamlining installation by combining drilling and tapping into one step. This reduces assembly time, lowers labor costs, and increases productivity in high-volume industrial settings, while the external hex drive and flange provide secure, tool-friendly installation and improved clamp load.

Specification Summary & Compliance

This screw features a No. 6-20 thread size with a 0.138" thread diameter and approximately 20 threads per inch, conforming to standard inch-series thread forming (BSD) specifications. The fully threaded 5/8" length and right-hand thread direction ensure consistent performance. It is manufactured to be RoHS 3 (2015/863/EU) Compliant and REACH (EC 1907/2006) Compliant, meeting stringent environmental and safety standards for industrial use.
