S-94209A417 M2.5 x 12 mm Tapping Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with zinc-plated steel construction, extending service life in demanding industrial environments
• Maximum torque transmission and reduced cam-out with Torx Plus IP8 drive, ensuring efficient installation and tool longevity
• Reliable thread forming in soft materials like aluminum, brass, and copper, creating strong, permanent threads without pre-tapping
• Enhanced pull-out resistance from the Tri-Lobe shank design, providing superior holding power in assembled components
• Full threading for maximum grip length along the entire 12mm shaft, ensuring consistent clamping force across the joint
• Broad industrial compliance meeting RoHS 3 and REACH standards, making them suitable for global supply chains and regulated industries
• Pan head design with standard profile for a low-profile finish and good bearing surface, suitable for various assembly requirements

Professional Applications & Engineering Value

These M2.5 x 0.45 mm zinc-plated steel Torx Plus tapping screws are engineered to solve common fastening challenges in aluminum, brass, and copper assemblies. The thread forming design eliminates the need for pre-tapped holes, reducing assembly steps and potential for cross-threading. The Tri-Lobe shank displaces material during installation, creating a tight interference fit that resists vibration loosening. Combined with the Torx Plus IP8 drive, these screws deliver high torque transfer with minimal risk of stripping, making them ideal for high-volume production lines and precision equipment where reliability is critical. The zinc plating provides a durable barrier against oxidation, ensuring long-term performance in electronic enclosures, automotive components, and machinery.
