• Reliable thread forming technology creates stronger, more vibration-resistant connections in steel and sheet metal applications
• Maximum material penetration with 11mm drill tip length capable of drilling through materials up to 0.236" thick
• Easy installation and removal with external hex drive design that ensures secure tool engagement and prevents stripping
• Complete thread coverage with fully threaded shank for consistent holding power along the entire fastener length

Professional Applications & Engineering Value

These M6.3 metric tapping screws deliver exceptional engineering value in steel and sheet metal fabrication applications. The zinc-plated steel construction provides essential corrosion protection for industrial environments, while the thread forming technology eliminates the need for separate tapping operations, significantly reducing assembly time and costs. The integrated flanged design distributes clamping force evenly, preventing material deformation and ensuring secure fastening in thin-gauge materials. With their No. 3 drill tip and fully threaded configuration, these screws penetrate up to 0.236" thickness without pre-drilling, making them ideal for high-volume production lines where efficiency and reliability are paramount. The external hex drive ensures positive tool engagement, reducing the risk of fastener damage during installation.

Specification Summary & Compliance

These flanged tapping screws feature precise M6.3 thread sizing with right-hand threading and fully threaded configuration for maximum holding strength. Manufactured to DIN 7504 K and ISO 15480 standards, ensuring consistent dimensional accuracy and performance reliability. The screws maintain full compliance with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, making them suitable for use in regulated industries and international markets. The thread forming design creates permanent, vibration-resistant connections without generating chips or debris.
