S-90469A145 Length 70 mm DIN 7504 K, ISO 15480 Tapping Screws

Key Features & Benefits at a Glance

• Effortless Installation: Self-drilling tip eliminates pre-drilling, saving time and labor costs in steel and sheet metal applications.
• Superior Corrosion Resistance: Zinc-plated steel construction provides a durable barrier against rust, extending the screw's service life.
• High-Strength Fastening: Thread forming design creates strong, permanent threads in the base material for a secure, vibration-resistant hold.
• Optimized Grip & Distribution: Integrated flange design increases bearing surface area, preventing pull-through and distributing load more effectively.
• Streamlined Assembly: External hex head allows for high-torque installation with standard tools, speeding up the assembly process.
• Material-Specific Performance: Precision No. 3 drill tip is engineered to penetrate up to 0.207" (approx. 5.25 mm) of steel and sheet metal reliably.
• Guaranteed Consistency: Manufactured to DIN 7504 K standards, ensuring dimensional accuracy and reliable performance in demanding industrial environments.

Professional Applications & Engineering Value

This M5.5 x 70mm flanged tapping screw is engineered to solve critical challenges in metal assembly. Its thread forming (BSD) action cold-forms a mating thread in the material, eliminating chips and creating a tighter, stronger fit than thread-cutting alternatives. The zinc-plated steel body offers excellent corrosion resistance for indoor and protected outdoor applications. The combination of a self-drilling tip and fully threaded design allows for rapid, one-step installation in steel and sheet metal, drastically reducing assembly time and cost. The external hex drive and robust flanged head provide superior torque transmission and clamping force, making it an ideal choice for HVAC, electrical enclosures, and automotive components where vibration resistance and joint integrity are paramount.

Specification Summary & Compliance

This screw conforms to the dimensional and performance requirements of DIN 7504 K (equivalent to ISO 15480). It features a fully threaded M5.5 shank with a right-hand thread, an 8mm hex head, and an 11mm flange diameter. The product is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring it is free from hazardous substances for safe use in global markets.
