Key Features & Benefits at a Glance
- Superior torque transmission with Torx Plus IP8 drive, reducing cam-out and tool wear for efficient assembly.
- Enhanced corrosion resistance from zinc-plated steel construction, ensuring durability in various industrial environments.
- Reliable thread forming in soft materials like aluminum, brass, and copper, minimizing the need for pre-tapped holes.
- Exceptional holding power due to the tri-lobe shank design, providing secure fastening in lightweight metal applications.
- Optimized for coarse thread spacing (0.45mm pitch), enabling quick installation and strong engagement in non-ferrous metals.
- Fully threaded blunt tip for consistent performance and reduced risk of material splitting during insertion.
- Compliance with environmental standards including RoHS 3 and REACH, supporting sustainable and safe manufacturing practices.
Professional Applications & Engineering Value
This M2.5 metric tapping screw is engineered for precision fastening in aluminum, brass, and copper components, commonly used in electronics, automotive, and HVAC systems. The zinc-plated steel material offers reliable corrosion protection, while the Torx Plus IP8 drive ensures maximum torque transfer without slippage, reducing assembly time and tool damage. The tri-lobe shank and thread forming design displace material to create strong, permanent threads, eliminating the need for additional locking elements. This makes it ideal for applications where vibration resistance and high pull-out strength are critical, providing long-term reliability in demanding industrial environments.
Specification Summary & Compliance
This screw features M2.5 x 0.45mm coarse thread with a length of 4mm and tolerance of -0.8 to 0mm, ensuring precise fit in metric assemblies. It conforms to standard right-hand thread and fully threaded specifications for consistent performance. The product is manufactured to meet RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) compliance, adhering to strict environmental and safety regulations for industrial use.
