Professional Applications & Engineering Value

These M4.8 zinc-plated steel flanged tapping screws deliver exceptional value in industrial fastening applications where speed, reliability, and corrosion resistance are critical. The thread forming design creates permanent, high-strength threads in steel and sheet metal without chip formation, eliminating cleanup and ensuring secure connections. The integrated flange design provides superior clamping force distribution while the external hex drive allows for high-torque installation with standard tools. Particularly valuable in HVAC, electrical enclosures, and metal fabrication, these BSD tapping screws combine drilling and fastening in one operation, significantly reducing assembly time and labor costs while maintaining DIN 7504 K compliance for consistent performance across production runs.

Specification Summary & Compliance

This metric tapping screw features M4.8 diameter with 22mm length and 10.5mm flange diameter, manufactured to precise DIN 7504 K standards (equivalent to ISO 15480) for dimensional accuracy and performance reliability. The fully threaded design with right-hand thread direction and round shank cross-section ensures optimal thread engagement. The product meets RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) compliance requirements, making it suitable for regulated industrial applications while maintaining environmental responsibility standards.
