• Optimized for coarse threading with a 0.45mm pitch, ensuring quick installation and strong holding power in various applications.
• Fully threaded blunt tip design for consistent engagement and easy alignment, reducing the risk of cross-threading and material damage.
• Compliance with global standards including RoHS 3 and REACH, guaranteeing safe and environmentally responsible use in industrial settings.

Professional Applications & Engineering Value

These M2.5 thread forming screws are engineered to address common challenges in fastening aluminum, brass, and copper components, where traditional screws may strip threads or require additional tapping steps. The zinc-plated steel material offers excellent durability against corrosion, while the Torx Plus IP8 drive ensures maximum torque application without slippage, critical for high-volume assembly lines. The tri-lobe shank and coarse 0.45mm pitch work together to create strong, vibration-resistant threads in soft metals, reducing installation time and improving reliability in electronics, automotive, and machinery applications. This design minimizes the risk of material cracking and ensures consistent performance, making these metric tapping screws a trusted choice for engineers seeking efficiency and longevity.
