• Superior material compatibility with steel and sheet metal applications, ensuring reliable fastening performance
• Efficient installation through the No. 3 drilling tip and thread forming design, eliminating the need for pre-drilling
• Increased holding power with the 13.5mm flange diameter, distributing load evenly and preventing pull-through
• Secure torque transmission via the external hex drive, allowing for high tightening forces with standard tools
• Maximum thread engagement from fully threaded design, providing consistent clamping force along the entire length
• Regulatory compliance assurance meeting DIN 7504 K, RoHS 3, and REACH standards for global market acceptance

Professional Applications & Engineering Value

These M6.3 zinc-plated steel tapping screws deliver exceptional engineering value in steel and sheet metal fabrication applications. The thread forming design creates strong, permanent threads in base materials without generating chips, eliminating contamination risks in sensitive assemblies. The integrated No. 3 drilling tip penetrates up to 0.236" thickness, streamlining installation by combining drilling and tapping operations. The flanged head design with 13.5mm diameter provides superior bearing surface, reducing surface pressure and preventing material deformation. Manufactured to DIN 7504 K standards, these hex drive screws ensure consistent performance in automotive, electrical enclosure, and structural metalwork applications where vibration resistance and long-term reliability are critical.

Specification Summary & Compliance

This M6.3 x 16mm flanged tapping screw features precision metric threading with fully threaded configuration for maximum engagement. The zinc-plated steel construction provides durable corrosion protection while maintaining high tensile strength. Manufacturing complies with DIN 7504 K specifications (equivalent to ISO 15480) for dimensional accuracy and performance standards. Regulatory compliance includes RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) requirements, ensuring environmental safety and unrestricted use in industrial markets. The external hex drive and 10mm head width accommodate standard tooling for consistent installation torque.
