S-90769A118 Length 25 mm DIN 7504 N, ISO 7049 Tapping Screws

Key Features & Benefits at a Glance

• Superior Corrosion Resistance: Zinc-plated steel construction provides excellent protection against rust, ensuring long-term reliability in demanding industrial environments.
• Efficient Self-Tapping Installation: Thread forming technology and drilling tip eliminate the need for pre-drilling, significantly reducing assembly time and labor costs in materials like steel and aluminum.
• High Torque Transfer & Reduced Cam-Out: The Phillips No. 2 drive ensures a secure fit and minimizes tool slippage, providing reliable fastening and preventing damage to the screw head.
• Robust Penetration Capability: The specialized drill tip can penetrate up to 2.4mm thickness, making it ideal for fastening into sheet metal, stainless steel, and other tough materials.
• Versatile Material Compatibility: Engineered for use in a wide range of materials including steel, stainless steel, aluminum, fabric, insulation, and wood, offering exceptional application flexibility.
• Secure & Reliable Fastening: Fully threaded design with a 1.4mm metric pitch ensures maximum grip and vibration resistance, maintaining joint integrity under stress.
• Streamlined Assembly Process: The pan head design provides a low-profile, rounded finish that is easy to handle and install, improving overall workflow efficiency.

Professional Applications & Engineering Value

This M3.9 x 25mm zinc-plated steel tapping screw is engineered to solve common industrial fastening challenges. Its thread forming action creates strong, clean threads in ductile materials like steel, aluminum, and sheet metal without generating chips, preventing contamination in sensitive assemblies. The integrated drilling tip and fully threaded shank work in tandem to provide exceptional pull-out strength and resistance to loosening under vibration, a critical requirement in automotive, HVAC, and metal fabrication. The zinc-plated finish offers a cost-effective barrier against corrosion, extending service life in both indoor and mildly corrosive environments. By combining self-tapping efficiency with robust metric thread design, this screw reduces installation steps, minimizes tooling requirements, and delivers reliable, high-strength joints that withstand operational demands.
