S-90469A138 Length 25 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 self-drilling installation with integrated No. 3 drill tip that eliminates pre-drilling, saving labor time and costs
• Enhanced load distribution through flanged design that provides wider bearing surface and prevents pull-through in thin materials
• Secure thread formation with thread forming technology that creates strong, vibration-resistant connections in steel and sheet metal
• Optimized torque transmission with external hex drive design allowing high tightening forces without stripping
• Maximum thread engagement through fully threaded shank ensuring consistent clamping force along the entire fastener length
• Regulatory compliance assurance meeting RoHS 3 and REACH standards for safe, environmentally responsible manufacturing

Professional Applications & Engineering Value

These M5.5 zinc-plated steel flanged tapping screws deliver exceptional engineering value in steel and sheet metal applications where vibration resistance and corrosion protection are critical. The thread forming design creates precise mating threads without generating chips, eliminating contamination risks in electrical enclosures, automotive assemblies, and structural frameworks. The integrated No. 3 drill tip with 10mm length penetrates up to 0.207" thickness, streamlining installation in production environments. The flanged head distributes clamping force effectively across wider surfaces, preventing material deformation in thin-gauge applications while the external hex drive ensures reliable torque transmission during high-volume assembly operations.

Specification Summary & Compliance
