S-90822A360 Length 1" Tapping Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with 410 stainless steel construction for long-lasting performance in harsh industrial environments
• Efficient self-drilling capability with No. 2 drill tip eliminates pre-drilling requirements, reducing installation time and labor costs
• Enhanced torque transmission through external hex drive design prevents stripping and ensures secure fastening in high-torque applications
• Integrated flange design provides wider bearing surface for improved load distribution and vibration resistance
• Optimized thread forming with BSD tapping method creates strong, permanent threads in steel and sheet metal substrates
• Maximum drilling capacity of 0.098" thickness handles various sheet metal and steel applications with consistent performance
• Full regulatory compliance with RoHS 3 and REACH standards ensures environmental responsibility and global market acceptance

Professional Applications & Engineering Value

These 410 stainless steel flanged tapping screws deliver exceptional engineering value in demanding metal fabrication applications. The self-drilling tip with 3/16" length and No. 2 geometry enables direct installation into steel, stainless steel, and sheet metal without pilot holes, significantly reducing assembly time and tooling requirements. The thread forming BSD design creates precise, cold-formed threads that provide superior pull-out strength and vibration resistance compared to conventional fastening methods. The combination of external hex drive and integrated flange ensures maximum torque transmission while distributing clamping force evenly across the work surface, preventing material deformation and maintaining joint integrity in high-stress industrial environments.
