S-90769A165 Length 19 mm DIN 7504 N, ISO 7049 Tapping Screws

Key Features & Benefits at a Glance

• Eliminates pre-drilling requirements with a self-drilling tip that penetrates up to 6mm thickness, saving significant labor time and tooling costs.
• Superior corrosion resistance provided by the zinc-plated steel construction, ensuring long-term reliability in various industrial environments.
• High-strength thread forming creates secure, vibration-resistant fastenings in materials like steel, stainless steel, and aluminum without stripping.
• Optimized for quick installation featuring a Phillips No. 3 drive for efficient torque transfer and a pan head for stable seating.
• Full threading with 1.8mm pitch ensures maximum grip and pull-out resistance across the entire 19mm length for durable assemblies.
• Versatile material compatibility allowing reliable use in steel, aluminum, fabric, insulation, sheet metal, and wood applications.
• Guaranteed dimensional precision manufactured to DIN 7504 N standards for consistent performance and interchangeability.

Professional Applications & Engineering Value

These M6.3 metric tapping screws are engineered to solve common assembly challenges in metal fabrication, construction, and HVAC industries. The zinc-plated steel material provides essential corrosion protection for outdoor or humid environments, while the self-drilling tip eliminates the need for separate drilling operations—reducing installation time by up to 50% in sheet metal and structural steel applications. The thread-forming design creates stronger threads in ductile materials like aluminum and stainless steel by displacing rather than removing material, resulting in higher fatigue resistance and secure fastening even under vibration. Fully compatible with automated driving systems, these screws deliver reliable performance in high-volume manufacturing while meeting strict industrial specifications.

Specification Summary & Compliance

This M6.3 x 19mm tapping screw features metric threading with 1.8mm pitch and full threading along the 7mm minimum thread length. Manufactured to DIN 7504 N specifications (equivalent to ISO 7049) for dimensional accuracy and performance consistency. Compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, ensuring safe use in industrial and consumer applications worldwide.
