S-90822A370 Length 1 1/4" Tapping Screws

Key Features & Benefits at a Glance

• Eliminates pre-drilling with integrated drilling tip that penetrates up to 0.098" thickness in steel and sheet metal, reducing installation time and labor costs.
• Superior corrosion resistance provided by 410 Stainless Steel construction, ensuring long-term reliability in harsh industrial environments.
• High-torque driving capability with external hex head design, allowing for secure fastening and reduced tool slippage during installation.
• Enhanced load distribution from the flanged design, minimizing surface damage and providing a wider bearing area for secure connections.
• Secure thread formation through thread-forming tapping method, creating strong, vibration-resistant threads in base materials without chip removal.
• Versatile material compatibility for use in steel, stainless steel, and sheet metal applications, streamlining inventory for various projects.
• Regulatory compliance assurance with RoHS 3 and REACH standards, meeting international environmental and safety requirements.

Professional Applications & Engineering Value

These self-drilling tapping screws deliver exceptional value in industrial fastening by combining 410 Stainless Steel durability with efficient installation. The integrated drilling tip (No. 2 type) eliminates separate drilling operations, significantly reducing assembly time in steel, stainless steel, and sheet metal applications. The thread-forming technology creates precise, strong threads without generating chips, preventing contamination in sensitive environments. With fully threaded design and external hex drive, these screws provide reliable clamping force and easy installation using standard tools. The flanged construction distributes pressure evenly, reducing the risk of material distortion while maintaining secure connections in HVAC, metal fabrication, and machinery assembly where vibration resistance is critical.

Specification Summary & Compliance

This No. 8-18 x 1-1/4" tapping screw features a 0.164" thread diameter with 18 threads per inch in right-hand thread direction, manufactured to BSD tapping screw standards. The screw is fully threaded with round shank cross-section and includes a flange diameter of 0.348". Compliance includes RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring environmental safety and restricted substance adherence for industrial applications.
