S-90769A159 Length 50 mm DIN 7504 N, ISO 7049 Tapping Screws

Key Features & Benefits at a Glance

• Superior material durability with zinc-plated steel construction providing excellent corrosion resistance for long-lasting performance in harsh industrial environments.
• Efficient thread forming technology creates strong, permanent threads in materials without pre-drilling, reducing installation time and labor costs.
• Optimized drill tip design with 11mm length enables quick penetration through materials up to 5.25mm thickness, ensuring secure fastening in steel, aluminum, and sheet metal.
• Full threading along 39mm minimum length delivers maximum grip and holding power across the entire fastener engagement area.
• Industry-standard Phillips No. 3 drive allows for efficient installation with common tools while the pan head design provides a low-profile, finished appearance.
• Precision metric threading with 1.8mm pitch ensures consistent, reliable performance in metric-based applications and equipment.
• Comprehensive material compatibility works effectively in steel, stainless steel, aluminum, fabric, insulation, sheet metal, and wood applications.

Professional Applications & Engineering Value

These M5.5 thread forming tapping screws deliver exceptional engineering value by solving critical fastening challenges in industrial assembly operations. The zinc-plated steel construction combined with thread forming technology eliminates the need for separate tapping operations, significantly reducing installation time and production costs. The specialized drill tip penetrates materials up to 5.25mm thick without pilot holes, making them ideal for sheet metal fabrication, aluminum framing, and steel construction applications. The fully threaded design ensures maximum load distribution while the Phillips drive system provides reliable torque transmission during installation. These screws maintain structural integrity in vibration-prone environments, offering superior performance in industrial machinery, electrical enclosures, and building construction projects where reliability is paramount.
