S-90469A106 Length 25 mm DIN 7504 K, ISO 15480 Tapping Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with zinc-plated steel construction, extending service life in demanding industrial environments.
• Efficient installation without pre-drilling thanks to the integrated No. 2 drill tip that penetrates steel and sheet metal up to 0.089" thick.
• Enhanced grip and load distribution from the flanged hex head design, reducing the risk of loosening under vibration.
• High thread engagement and pull-out strength with fully threaded, thread-forming design for secure fastening in metal substrates.
• Quick and secure driving using standard external hex tools, improving assembly speed and torque application.
• Reliable performance in harsh conditions with compliance to RoHS 3 and REACH environmental standards.
• Consistent dimensional accuracy meeting DIN 7504 K specifications for dependable interchangeability.

Professional Applications & Engineering Value

These M3.5 x 25mm zinc-plated steel tapping screws are engineered to address common challenges in steel and sheet metal fabrication, where speed, durability, and reliability are critical. The thread-forming tapping method and fully threaded shank create strong, permanent threads in base materials, eliminating the need for separate tapping operations and reducing assembly time. The flanged hex head provides a larger bearing surface, distributing clamp load effectively to prevent material distortion and maintain joint integrity under dynamic loads. With a precision drilling tip capable of penetrating up to 0.089" thickness, these screws streamline workflows in automotive, construction, and machinery assembly, ensuring consistent performance while meeting stringent DIN 7504 K standards for quality assurance.

Specification Summary & Compliance

This M3.5 x 25mm metric screw features a fully threaded, right-hand thread with thread-forming design per BSD type. It conforms to DIN 7504 K (equivalent to ISO 15480) for dimensional and performance requirements, ensuring precise Class 2A thread tolerance. The product is RoHS 3 (2015/863/EU) Compliant and REACH (EC 1907/2006) Compliant, adhering to environmental and safety regulations for industrial use.
