S-90822A320 Length 4" Tapping Screws

Key Features & Benefits at a Glance

• Fast, one-step installation with integrated self-drilling tip that eliminates pre-drilling, saving labor time and costs in steel, stainless steel, and sheet metal assemblies.
• Superior corrosion resistance provided by 410 Stainless Steel construction, ensuring long-term reliability in demanding industrial environments.
• High-torque driving capability with the external hex head design, allowing for secure fastening and reduced risk of stripping during installation.
• Enhanced load distribution and vibration resistance from the integrated flange, which helps prevent loosening and maintains joint integrity.
• Optimized for thick materials with a drilling capacity of up to 0.15" and a fully threaded 4" length, providing strong, continuous engagement in deep applications.
• Consistent, reliable thread formation using the thread-forming (BSD) tapping method, which creates strong, precise threads without generating chips.
• Compliance with major environmental regulations including RoHS 3 and REACH, ensuring safe, sustainable use in global supply chains.

Professional Applications & Engineering Value

Engineered for high-efficiency fastening in steel, stainless steel, and sheet metal, these self-drilling tapping screws eliminate the need for separate drilling and tapping operations, significantly reducing assembly time and potential alignment errors. The 410 Stainless Steel material offers excellent strength and corrosion resistance, crucial for outdoor, marine, or chemically exposed settings. The hex head with external drive ensures high torque application, while the flanged design increases clamping area to resist vibration loosening. The No. 3 drill tip and thread-forming BSD style enable clean, secure threads in materials up to 0.15" thick, making these screws ideal for HVAC, metal framing, and industrial machinery where durability and speed are paramount.

Specification Summary & Compliance

This No. 10-16 x 4" screw features a right-hand thread with approximately 16 threads per inch and a 0.19" thread diameter, manufactured to standard inch system tolerances. The fully threaded shank and thread-forming tapping method ensure consistent performance. It is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, confirming its adherence to strict environmental and safety standards for industrial use.
