S-90469A123 Length 16 mm DIN 7504 K, ISO 15480 Tapping Screws

Key Features & Benefits at a Glance

• Eliminates pre-drilling requirements with integrated drilling tip that penetrates up to 0.173" thick steel and sheet metal
• Superior corrosion resistance provided by zinc-plated steel construction for extended service life in industrial environments
• Enhanced fastening stability through the flanged design that distributes load evenly and prevents sinking
• Optimized installation efficiency with external hex drive allowing high torque application and secure tightening
• Reliable thread formation using thread forming technology that creates strong, vibration-resistant connections in metal substrates
• Full-length threading ensures maximum grip along the entire 16mm length for superior holding power
• Regulatory compliance assurance meeting DIN 7504 K standards for consistent quality and performance

Professional Applications & Engineering Value

These M4.8 x 16mm zinc-plated steel flanged tapping screws deliver exceptional value in metal fabrication and assembly operations. The thread forming technology eliminates the need for separate tapping operations, creating precise threads that resist loosening under vibration - a critical advantage in automotive, machinery, and electrical enclosure applications. The integrated drilling tip with No. 2 point design penetrates steel and sheet metal up to 0.173" thick, significantly reducing installation time and labor costs. The flanged hex head provides a larger bearing surface that prevents pull-through in thin materials while the external drive accommodates standard tools for rapid assembly. This combination of features makes these BSD tapping screws ideal for high-volume production environments where reliability and efficiency are paramount.

Specification Summary & Compliance

This metric tapping screw features M4.8 diameter with 16mm length and fully threaded right-hand configuration. The screw meets DIN 7504 K specifications (equivalent to ISO 15480) for thread forming screws, ensuring dimensional accuracy and performance consistency. The 10.5mm flange diameter provides enhanced clamping area while the 4.3mm head height and 8mm head width optimize tool clearance. Compliance with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations guarantees environmental safety and material restrictions adherence for global manufacturing applications.
