S-90469A127 Length 32 mm DIN 7504 K, ISO 15480 Tapping Screws

Key Features & Benefits at a Glance

• Effortless Installation: Self-drilling tip eliminates pre-drilling, saving time and labor costs in steel and sheet metal assembly.
• Superior Corrosion Resistance: Zinc-plated steel construction provides a durable barrier against rust, ensuring long-term reliability in harsh industrial environments.
• High-Strength Fastening: Thread forming tapping method creates strong, secure threads in the base material, reducing the risk of loosening under vibration.
• Secure Flanged Design: Integrated flange distributes clamping pressure over a wider area, enhancing joint stability and preventing surface damage.
• Optimized for High-Volume Use: Compliant with DIN 7504 K and ISO 15480 standards, guaranteeing consistent quality and dimensional accuracy for repeatable performance.
• Robust Drive Engagement: External hex head design allows for high-torque application with standard tools, ensuring a tight, reliable fastening.
• Versatile Penetration Capability: Drilling tip is engineered to penetrate up to 0.173" (approx. 4.4 mm) of material, making it ideal for a range of sheet metal thicknesses.

Professional Applications & Engineering Value

This M4.8 x 32mm tapping screw is engineered to solve critical fastening challenges in steel and sheet metal fabrication. Its zinc-plated steel material and thread forming design eliminate the need for separate tapping operations, significantly speeding up assembly lines while creating strong, wear-resistant threads. The fully threaded shank and flanged head work in tandem to provide superior clamp load distribution and vibration resistance, which is crucial in automotive, HVAC, and electrical enclosure applications. The specialized drilling tip ensures clean, precise holes without pilot drilling, reducing tool wear and preventing material deformation. By integrating drilling, tapping, and fastening into a single operation, this screw delivers exceptional engineering value by lowering total installation cost and improving structural integrity in demanding industrial settings.
