S-90769A177 Length 100 mm DIN 7504 N, ISO 7049 Tapping Screws

Key Features & Benefits at a Glance

• Effortless installation with integrated 12 mm drill tip that eliminates pre-drilling, saving time and labor costs in steel, aluminum, and sheet metal assemblies.
• Superior corrosion resistance from zinc-plated steel construction, ensuring long-term reliability in harsh industrial environments.
• High-strength thread forming creates durable, vibration-resistant threads in materials up to 6 mm thick, reducing the risk of loosening.
• Optimized drive efficiency with Phillips No. 3 drive for secure torque transfer and reduced cam-out during high-speed applications.
• Full-thread engagement along the 100 mm length provides maximum pull-out resistance and uniform stress distribution.
• Broad material compatibility for use in steel, stainless steel, aluminum, fabric, insulation, sheet metal, and wood, simplifying inventory.
• Pan head design offers a low-profile, rounded bearing surface that minimizes surface damage and allows for flush or semi-flush installation.

Professional Applications & Engineering Value

These M6.3 metric tapping screws are engineered to solve common fastening challenges in metal fabrication, construction, and HVAC installations. The thread forming design cold-forms mating threads without generating chips, preventing contamination in electrical enclosures and insulation systems. Made from zinc-plated steel, they resist rust in outdoor or humid conditions, while the fully threaded shank and drill tip enable rapid penetration through 6 mm thick sheet metal, stainless steel, and aluminum. This combination eliminates separate drilling and tapping steps, reducing assembly time by up to 50% in high-volume production lines and ensuring consistent clamp force in structural frameworks.

Specification Summary & Compliance

This screw meets DIN 7504 N and ISO 7049 standards for dimensional accuracy and thread form, with a metric M6.3 diameter, 1.8 mm pitch, and 100 mm length. It is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring safe use in regulated industrial and consumer applications. The right-hand thread and thread forming tapping method adhere to international mechanical fastening specifications for reliability.
