S-90469A126 Length 25 mm DIN 7504 K, ISO 15480 Tapping Screws

Key Features & Benefits at a Glance

• Eliminates pre-drilling operations with integrated drill tip, reducing installation time and labor costs in steel and sheet metal applications
• Superior corrosion resistance through zinc-plated steel construction, ensuring long-term reliability in demanding industrial environments
• Enhanced fastening security with integrated flange design that distributes load evenly and prevents pull-through in thin materials
• High-torque installation capability with external hex head design, allowing for secure driver engagement and efficient power transfer
• Optimized thread forming action through BSD tapping screw design that creates strong, permanent threads in base materials
• Maximum material penetration with 9.3mm drill tip length capable of drilling through 0.173" thick materials without pilot holes
• Full-length threading provides consistent holding power along the entire screw length for superior fastening integrity

Professional Applications & Engineering Value

These M4.8 zinc-plated steel tapping screws deliver exceptional value in industrial fastening applications where efficiency and reliability are paramount. The combination of thread forming technology and integrated drill tip eliminates the need for separate drilling and tapping operations, significantly reducing assembly time in steel and sheet metal fabrication. The flanged hex head design provides superior clamping force distribution while the external hex drive ensures high torque transmission without cam-out. Engineered for DIN 7504 K compliance, these self-drilling screws create precise, strong threads that resist vibration loosening, making them ideal for automotive, electrical enclosure, and structural panel applications where joint integrity is critical.

Specification Summary & Compliance

This M4.8 x 25mm flanged tapping screw features precision metric threading with fully threaded right-hand configuration and No. 2 drill tip geometry. Manufactured to DIN 7504 K specifications with thread forming (BSD) design for optimal performance in steel and sheet metal substrates. The screw demonstrates compliance with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental standards, ensuring regulatory adherence for international industrial applications. Critical dimensions include 8mm hex head width, 4.3mm head height, and 10.5mm flange diameter for consistent performance across production runs.
