S-90469A153 Length 25 mm DIN 7504 K, ISO 15480 Tapping Screws

Key Features & Benefits at a Glance

• Eliminates pre-drilling operations with integrated No. 3 drill tip that penetrates up to 0.236" (6mm) of steel and sheet metal
• Superior corrosion resistance provided by zinc-plated steel construction for extended service life in industrial environments
• Enhanced installation efficiency through external hex drive design that prevents cam-out and allows high torque application
• Secure fastening with vibration resistance achieved through thread forming technology that creates strong, permanent threads in base material
• Distributed load bearing thanks to the integrated flange design that increases clamping surface area
• Full-length thread engagement ensures maximum holding power across the entire 25mm length
• Reliable performance in demanding applications with full compliance to DIN 7504 K standards for quality assurance

Professional Applications & Engineering Value

These M6.3 zinc-plated steel flanged tapping screws deliver exceptional value in industrial fastening applications where time efficiency and reliability are critical. The thread forming design creates permanent, high-strength threads in steel and sheet metal substrates without chip formation, eliminating cleanup requirements and ensuring secure fastening in vibration-prone environments. The combination of No. 3 drill tip and fully threaded shank allows for single-operation installation in materials up to 0.236" thick, significantly reducing assembly time and labor costs. The external hex drive provides positive torque transmission for consistent installation, while the integrated flange distributes clamping force over a wider area, preventing material distortion in thin-gauge applications. These metric tapping screws are engineered specifically for demanding industrial settings where self-drilling capability and reliable performance in steel and sheet metal are paramount requirements.
