S-94209A351 M2.5 x 16 mm DIN 7500 C Tapping Screws

Key Features & Benefits at a Glance

• Superior material strength and corrosion resistance with zinc-plated steel construction, ensuring long-lasting performance in demanding industrial environments
• Exceptional holding power in soft materials due to thread forming technology that creates strong, permanent threads without chip removal
• Optimized for aluminum, brass, and copper applications with tri-lobe shank design that reduces driving torque while maintaining secure fastening
• Reliable installation and removal with Phillips No. 1 drive that provides consistent torque transfer and minimizes cam-out
• Precision dimensional accuracy with fully threaded M2.5 coarse thread (0.45mm pitch) ensuring consistent performance across all applications
• Enhanced assembly efficiency with pan head design that offers excellent driver engagement and flush mounting capability
• Comprehensive compliance assurance meeting DIN 7500 C standards for thread forming screws in non-ferrous metals

Professional Applications & Engineering Value

These M2.5 tapping screws deliver exceptional engineering value through their specialized thread forming technology and zinc-plated steel construction. The tri-lobe shank cross-section significantly reduces installation torque while creating strong, permanent threads in aluminum, brass, and copper components without generating chips that could contaminate sensitive assemblies. This makes them ideal for electronics enclosures, automotive components, and precision machinery where reliable fastening in soft metals is critical. The fully threaded design ensures maximum holding power along the entire 16mm length, while the Phillips drive provides consistent installation performance. These metric coarse thread screws solve common challenges of strip-out and weak thread engagement in non-ferrous materials, delivering superior pull-out resistance and vibration performance in demanding industrial applications.

Specification Summary & Compliance

This M2.5 x 16mm tapping screw features precision metric thread specifications with 0.45mm coarse pitch and ±0.55mm length tolerance for consistent performance. Manufactured to DIN 7500 C standards for thread forming screws, ensuring reliable performance in non-ferrous metals. The screws are fully compliant with RoHS 3 (2015/863/EU) environmental directives and REACH (EC 1907/2006) regulations, making them suitable for use in regulated industries and international markets. The right-hand thread direction and blunt tip design facilitate proper alignment and installation in various aluminum, brass, and copper applications.
