S-90469A112 Length 25 mm DIN 7504 K, ISO 15480 Tapping Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with zinc-plated steel construction, ensuring long-term reliability in harsh industrial environments.
• Effortless installation thanks to the integrated drilling tip that eliminates pre-drilling, saving time and labor costs in steel and sheet metal applications.
• Enhanced load distribution from the flanged design, providing a wider bearing surface and reducing the risk of material damage.
• Secure, high-torque fastening with an external hex drive head, allowing for reliable tightening with standard tools.
• Optimized thread engagement through thread-forming technology, creating strong, vibration-resistant connections in metal substrates.
• Full-length threading for maximum grip and holding power across the entire 25mm length, ideal for varying material thicknesses.
• Compliance with international standards including DIN 7504 K, ensuring consistent quality and performance in professional settings.

Professional Applications & Engineering Value

Engineered for demanding steel and sheet metal applications, these M3.9 tapping screws deliver exceptional value by addressing common installation challenges. The zinc-plated steel material offers robust corrosion protection, while the thread-forming design and drilling tip enable direct fastening without pilot holes—reducing assembly steps and minimizing tool wear. With a maximum drilling thickness of 0.095" and fully threaded shank, they ensure reliable performance in automotive, machinery, and construction sectors where vibration resistance and durability are critical. The flanged hex head further enhances stability, making these screws a top choice for high-stress industrial environments.
