S-94209A415 M2.5 x 8 mm Tapping Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with zinc-plated steel construction, ensuring long-term reliability in demanding industrial environments
• Enhanced torque transmission and reduced cam-out thanks to the Torx Plus IP8 drive system, providing secure installation and minimizing tool wear
• Excellent thread-forming capability in aluminum, brass, and copper without pre-tapping, reducing assembly time and labor costs
• Secure anti-rotation performance from the tri-lobe shank design, preventing loosening under vibration and dynamic loads
• Optimized coarse thread spacing (0.45mm pitch) for faster installation and strong holding power in softer materials
• Full threading and blunt tip for consistent engagement depth and prevention of material damage during installation
• Compliance with RoHS 3 and REACH regulations, ensuring environmental safety and meeting global supply chain requirements

Professional Applications & Engineering Value

These M2.5 x 0.45mm thread forming screws are engineered specifically for fastening in aluminum, brass, and copper applications where traditional threaded fasteners may fail. The zinc-plated steel construction provides essential corrosion protection for electronics, automotive components, and machinery exposed to humid or mildly corrosive conditions. The Torx Plus IP8 drive delivers up to 20% higher torque transmission compared to standard drives, eliminating cam-out issues and reducing assembly defects in high-volume production. The tri-lobe shank cross-section creates secure interference fit in parent material, preventing rotation under vibration – a critical advantage in automotive electronics, HVAC systems, and precision instrument manufacturing where reliability is paramount.

Specification Summary & Compliance

Manufactured to precise metric standards with M2.5 thread size and 0.45mm coarse pitch. Features fully threaded design with 8mm length and tolerance of -0.8 to 0mm for consistent performance. Compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations. The thread forming tapping method and right-hand coarse spacing ensure reliable fastening in non-ferrous materials without requiring pre-tapped holes.
