S-90469A113 Length 32 mm DIN 7504 K, ISO 15480 Tapping Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with zinc plating, extending service life in demanding industrial environments.
• Efficient, self-tapping installation with thread forming technology that creates strong, durable threads without pre-drilling in steel and sheet metal.
• High clamp load and secure fastening provided by the integrated flange, which acts as a built-in washer for a larger bearing surface.
• Quick and easy drive engagement with the external hex head, allowing for high-torque application with standard tools.
• Optimized for material up to 0.095" thick, featuring a No. 2 drilling tip that penetrates and starts threads efficiently.
• Full-length threading (32mm) ensures maximum grip and holding power along the entire shank for a secure assembly.
• Guaranteed dimensional accuracy and performance, manufactured to meet the rigorous DIN 7504 K standard for thread forming screws.

Professional Applications & Engineering Value

Engineered for high-performance fastening in steel and sheet metal, these M3.9 flanged tapping screws solve critical assembly challenges. The thread forming action displaces material rather than cutting it, resulting in stronger, more vibration-resistant threads with zero chip creation, eliminating cleanup and potential short circuits in electrical enclosures. The combination of a zinc-plated steel construction for corrosion protection and a drilling tip streamlines the process into a single operation—drilling, tapping, and fastening—significantly reducing labor time and cost in high-volume production lines for automotive, machinery, and metal fabrication.

Specification Summary & Compliance

This M3.9 x 32mm screw features a fully threaded, round shank with a right-hand thread direction and an external hex drive. It is manufactured to the precise dimensional and performance requirements of the DIN 7504 K (ISO 15480) standard for thread forming screws. 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 industrial markets.
