S-90469A124 Length 19 mm DIN 7504 K, ISO 15480 Tapping Screws

Key Features & Benefits at a Glance

• Enhanced corrosion resistance through zinc plating, extending service life in demanding industrial environments.
• Faster installation and reduced assembly costs with the integrated No. 2 self-drilling tip, eliminating the need for pre-drilling.
• Superior vibration resistance and holding power due to the thread-forming design, which creates strong, permanent threads in steel and sheet metal.
• Secure and stable fastening with the integrated flange, which acts as a built-in washer for increased load distribution.
• High-strength, durable connections made possible by the zinc-plated steel construction, suitable for heavy-duty applications.
• Efficient drive engagement with the external hex head, allowing for high torque application with standard tools.
• Reliable performance in materials up to 0.173" (4.4 mm) thick, as specified by the drill tip's maximum penetration capacity.

Professional Applications & Engineering Value

This M4.8 x 19mm flanged tapping screw is engineered to solve critical challenges in metal fabrication and assembly. Its self-drilling No. 2 tip and thread-forming technology allow for direct installation into steel and sheet metal without pilot holes, drastically reducing labor time and the risk of workpiece damage. The zinc-plated steel material provides excellent resistance to corrosion, ensuring long-term integrity in harsh conditions. The combination of a flanged head and external hex drive offers a secure, stable connection that withstands vibration and loosening, making it an ideal tapping screw for HVAC systems, automotive panels, and electrical enclosures where reliability is non-negotiable.
