S-90469A159 Length 70 mm DIN 7504 K, ISO 15480 Tapping Screws

Key Features & Benefits at a Glance

• Enhanced corrosion resistance with zinc-plated steel construction for extended service life in demanding industrial environments
• Superior fastening efficiency through thread-forming BSD design that creates strong, permanent threads without pre-drilling
• Maximum material penetration with specialized No. 3 drilling tip capable of drilling through steel and sheet metal up to 0.236" thickness
• Secure anti-loosening performance thanks to integrated flange design that distributes load and prevents sinking into materials
• Optimal torque transmission with external hex head drive that ensures reliable installation with standard tools
• Full-length thread engagement providing consistent clamping force along the entire 70mm length for superior joint integrity
• Environmental compliance assurance meeting RoHS 3 and REACH standards for safe industrial use

Professional Applications & Engineering Value

This M6.3 metric tapping screw delivers exceptional engineering value for professionals working with steel and sheet metal applications. The zinc-plated steel construction provides essential corrosion protection in industrial settings, while the thread-forming BSD design eliminates the need for separate tapping operations, significantly reducing installation time and labor costs. The integrated flange and hex head combination ensures uniform pressure distribution, preventing material deformation and maintaining structural integrity. With its No. 3 drilling tip, this screw effectively penetrates up to 0.236" thickness without pilot holes, making it ideal for construction, metal fabrication, and assembly lines where speed and reliability are critical. The fully threaded right-hand design guarantees maximum holding power across the entire fastener length.

Specification Summary & Compliance

Manufactured to DIN 7504 K specifications (equivalent to ISO 15480), this M6.3 x 70mm flanged tapping screw maintains precise dimensional accuracy with fully threaded right-hand configuration and external hex drive. The product complies with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, ensuring safe industrial use. The thread-forming BSD tapping method and 13.5mm flange diameter provide reliable performance in steel and sheet metal applications, backed by standardized manufacturing processes for consistent quality.
