S-90769A155 Length 25 mm DIN 7504 N, ISO 7049 Tapping Screws

Key Features & Benefits at a Glance

• Effortless installation with integrated 11mm drill tip that eliminates pre-drilling, saving time and labor costs in assembly operations
• Superior corrosion resistance through zinc-plated steel construction, ensuring long-term reliability in demanding industrial environments
• Exceptional material penetration capable of drilling through up to 5.25mm thickness in steel, stainless steel, and sheet metal applications
• Secure thread formation with thread forming technology that creates strong, vibration-resistant connections without damaging materials
• Wide compatibility with multiple materials including aluminum, fabric, insulation, and wood for versatile application across industries
• Optimized drive efficiency with Phillips No. 3 drive that provides reliable torque transfer and prevents cam-out during installation
• Complete thread engagement with fully threaded design that maximizes holding power across the entire screw length

Professional Applications & Engineering Value

These M5.5 metric tapping screws deliver exceptional engineering value by solving critical fastening challenges in metal fabrication and construction. The zinc-plated steel construction combined with thread forming technology eliminates the need for separate drilling operations, significantly reducing installation time while creating permanent, high-strength threads in parent materials. The specialized drill tip design ensures clean penetration through various thicknesses of steel, stainless steel, and aluminum without work hardening or material distortion. This makes them ideal for assembly lines, HVAC systems, electrical enclosures, and structural applications where vibration resistance and long-term reliability are paramount. The pan head with Phillips drive provides a balanced combination of driving efficiency and flush mounting capability, while the fully threaded configuration ensures maximum load distribution across joined materials.

Specification Summary & Compliance

These M5.5 x 25mm tapping screws feature precision metric thread with approximately 1.8mm pitch and minimum 14mm thread length, manufactured to exacting DIN 7504 N specifications ISO 7049 standards. The screws maintain proper thread engagement and dimensional accuracy for reliable performance in industrial applications. Compliance with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations ensures environmental safety and material sustainability, making them suitable for global industrial supply chains and regulated manufacturing environments.
