S-90469A167 Length 140 mm DIN 7504 K, ISO 15480 Tapping Screws

Key Features & Benefits at a Glance

• Enhanced corrosion resistance with zinc-plated steel construction, ensuring long-term reliability in demanding industrial environments.
• Superior holding power from the integrated 13.5mm flange, distributing load evenly and reducing the risk of material pull-through.
• Efficient thread-forming capability that creates strong, precise threads in steel and sheet metal without pre-tapping, saving installation time and labor.
• Quick and secure installation with the external hex drive and No. 3 drill tip, allowing for high-torque application and self-drilling into materials up to 0.236" thick.
• Full threading along the 140mm length provides consistent grip and maximum fastening strength across the entire engagement area.
• Compliance with DIN 7504 K standards guarantees dimensional accuracy and performance reliability for professional use.
• Environmental and safety adherence through RoHS 3 and REACH compliance, making them suitable for regulated industrial applications.

Professional Applications & Engineering Value

These M6.3 zinc-plated steel flanged tapping screws are engineered to address common challenges in steel and sheet metal fabrication, such as material fatigue and installation inefficiency. The thread-forming technology eliminates the need for separate tapping operations, reducing assembly time and minimizing tool wear. With a No. 3 drill tip and fully threaded design, they penetrate up to 0.236" thick materials smoothly, creating secure, vibration-resistant connections. The external hex drive ensures easy handling with standard tools, while the flange enhances clamping force, preventing loosening under dynamic loads. Ideal for construction, automotive, and heavy machinery, these screws deliver high-performance fastening with consistent results in rigorous conditions.
