• Enhanced holding power with thread forming technology that creates stronger, more secure threads in base materials
• Simplified assembly with flanged hex head design providing both driving stability and built-in washer functionality
• Reliable performance in steel, stainless steel, and sheet metal applications with precise BSD thread specifications
• Environmental compliance meeting RoHS 3 and REACH standards for sustainable industrial operations
• Optimized thread engagement with 14 threads per inch and full threading along the 1-1/2" length

Professional Applications & Engineering Value

This No. 12 flanged hex head tapping screw delivers exceptional value in industrial fastening applications where material integrity and installation efficiency are critical. The 410 stainless steel composition provides excellent resistance to corrosion and oxidation, making it ideal for harsh environments while maintaining structural strength. The integrated drilling tip (No. 3 type) eliminates the need for separate drilling operations, significantly reducing assembly time and labor costs in steel, stainless steel, and sheet metal applications. The thread forming technology creates precise, strong threads without generating chips, ensuring secure fastening in critical joints. The flanged hex head design combines the torque transmission capability of an external hex with the load distribution benefits of an integrated washer, preventing loosening under vibration and distributing clamping force effectively across joined surfaces.
