S-90822A327 Length 3/8" Tapping Screws

Key Features & Benefits at a Glance

• Eliminates pre-drilling requirements with integrated drilling tip that penetrates up to 0.035" thickness in steel and sheet metal
• Superior corrosion resistance through 410 Stainless Steel construction for extended service life in demanding environments
• Enhanced fastening stability with flanged hex head design that distributes load evenly and prevents pull-through
• Secure thread formation using thread forming technology that creates strong, vibration-resistant connections without chip removal
• High-strength external hex drive provides superior torque transmission during installation with standard tools
• Full threading along 3/8" length ensures maximum grip and holding power throughout the entire fastener engagement
• Right-hand BSD screw design offers reliable performance in steel, stainless steel, and sheet metal applications

Professional Applications & Engineering Value

These No. 8-18 TPI flanged hex head tapping screws deliver exceptional engineering value by solving critical installation challenges in metal fabrication. The 410 Stainless Steel composition provides excellent corrosion resistance while maintaining high tensile strength, making these thread forming screws ideal for outdoor equipment, electrical enclosures, and HVAC systems. The integrated drilling tip eliminates the time-consuming pre-drilling process, significantly reducing assembly time and labor costs in high-volume production environments. When used in sheet metal applications up to 0.035" thickness, the BSD screw type creates durable, vibration-resistant threads that maintain integrity under dynamic loads. The external hex drive ensures reliable installation with standard tools, while the flange provides superior clamping force distribution, preventing material deformation in thin-gauge metals.

Specification Summary & Compliance

This No. 8-18 x 3/8" tapping screw features precise 0.164" thread diameter with 18 threads per inch and right-hand threading throughout its entire 3/8" length. Manufactured to BSD screw type standards with thread forming technology and 1/4" hex head configuration. The product is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring environmental safety and industrial compliance standards are met for global manufacturing applications.
