S-90822A148 Length 1/2" Tapping Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with 410 stainless steel construction for long-term durability in harsh industrial environments
• Integrated drilling tip technology eliminates pre-drilling requirements, saving installation time and labor costs
• Flanged head design provides wider bearing surface for improved load distribution and vibration resistance
• Thread forming tapping method creates stronger, more secure threads in steel and sheet metal applications
• External hex drive style ensures maximum torque transmission and prevents stripping during installation
• Full threading along entire shank length delivers consistent holding power throughout the fastener engagement
• Environmental compliance assurance with RoHS 3 and REACH regulations for global market acceptance

Professional Applications & Engineering Value

These No. 6 flanged tapping screws are engineered specifically for challenging metal joining applications where corrosion resistance and installation efficiency are critical. The 410 stainless steel composition provides excellent strength while resisting oxidation in demanding environments. The thread forming design with 20 TPI creates permanent, high-strength threads in steel, stainless steel, and sheet metal substrates without chip formation. The integrated drilling tip penetrates up to 0.09" thickness, eliminating secondary drilling operations and reducing assembly time. The flanged hex head combines the torque capability of external drive systems with the stability of a washer-like bearing surface, making these BSD type screws ideal for automotive, HVAC, and metal fabrication applications where vibration resistance and quick installation are paramount.

Specification Summary & Compliance

This No. 6 x 1/2" flanged tapping screw features precision 0.138" thread diameter with 20 TPI right-hand threads in Class 2A inch system tolerances. The thread forming tapping method complies with BSD screw type standards, while the external hex drive and fully threaded shank ensure consistent performance. Manufacturing and material compliance includes RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, confirming environmental safety and global market acceptability for industrial fastener applications.
