S-90469A102 Length 13 mm DIN 7504 K, ISO 15480 Tapping Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with zinc-plated steel construction, extending service life in demanding industrial environments.
• Efficient thread-forming installation using BSD technology eliminates the need for pre-drilling, reducing assembly time and labor costs.
• Enhanced grip and load distribution from the integrated flange design, preventing loosening under vibration and improving joint integrity.
• High drilling capability with a No. 2 drill tip that penetrates steel and sheet metal up to 0.089" thickness, ensuring reliable fastening in thin materials.
• Secure torque transmission via the external hex drive head, allowing for high tightening forces without stripping.
• Full threading for maximum holding power along the entire 13mm length, providing consistent clamping force in steel and sheet metal applications.
• Compliance with international standards including DIN 7504 K, ensuring dimensional accuracy and performance reliability for global engineering projects.

Professional Applications & Engineering Value

These M3.5 x 13mm zinc-plated steel tapping screws are engineered to address common challenges in steel and sheet metal fabrication, where speed and durability are critical. The thread-forming BSD design creates strong, permanent threads in base materials without chip formation, reducing the risk of contamination and weak points. The flanged hex head offers a larger bearing surface, distributing load evenly to prevent surface damage and maintain seal integrity in assembled components. With a No. 2 drill tip that efficiently penetrates up to 0.089" thickness, these screws streamline production by combining drilling and tapping into one step, ideal for high-volume manufacturing lines and industrial fastener systems requiring consistent, vibration-resistant connections.

Specification Summary & Compliance

This metric tapping screw features M3.5 size, 13mm length, and full threading with a round shank cross-section for precise fit. Manufactured to DIN 7504 K specifications (equivalent to ISO 15480), it ensures dimensional accuracy and thread consistency. The product is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, confirming its suitability for environmentally conscious industrial applications without hazardous substances.
