S-90469A161 Length 80 mm DIN 7504 K, ISO 15480 Tapping Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with zinc-plated steel construction for extended service life in demanding industrial environments
• Efficient installation process through integrated drilling tip that eliminates pre-drilling requirements in steel and sheet metal
• Enhanced load distribution with flanged design that provides wider bearing surface and prevents pull-through
• Secure fastening performance with thread forming technology that creates strong, vibration-resistant threads in parent material
• Optimized torque transmission through external hex drive design for reliable tightening with standard tools
• Maximum material penetration with 80mm fully threaded length and capability to drill through 0.236" thick materials
• Industry-standard compatibility meeting DIN 7504 K specifications for consistent quality and performance

Professional Applications & Engineering Value

These M6.3 flanged tapping screws deliver exceptional engineering value in steel and sheet metal applications where traditional fastening methods prove inefficient. The thread forming design creates permanent, high-strength threads without chip formation, eliminating the risk of contamination in sensitive assemblies. The zinc-plated steel construction provides reliable corrosion protection while maintaining the mechanical strength required for structural applications. With the integrated drilling tip capable of penetrating up to 0.236" thickness, these screws significantly reduce installation time and labor costs in manufacturing, HVAC systems, and metal fabrication projects. The flanged head design ensures uniform clamping force distribution, preventing material distortion in thin-gauge applications.
