Professional Applications & Engineering Value

These M2.5 thread forming screws are specifically engineered to solve common fastening challenges in aluminum, brass, and copper applications. The Tri-Lobe shank design displaces material during installation, creating precisely formed threads that eliminate the need for tapping operations and reduce assembly time. Made from zinc-plated steel, these fasteners provide excellent corrosion protection while maintaining the strength required for demanding industrial environments. The Torx Plus IP8 drive system ensures maximum torque transmission, preventing screw head damage and reducing installation failures. Ideal for electronics enclosures, automotive components, and precision machinery where reliable fastening in soft metals is critical, these metric coarse thread screws deliver consistent performance and reduced total cost of ownership through their efficient installation and long-term reliability.

Specification Summary & Compliance

These M2.5 x 0.45mm pitch metric screws feature precise dimensional tolerances with a length tolerance of -0.8 to 0mm, ensuring consistent performance across production runs. Manufactured to metric thread standards with coarse thread spacing for optimal performance in non-ferrous materials. The fasteners are fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, making them suitable for global industrial applications requiring environmental compliance. The thread forming design follows industry-standard practices for creating reliable threads in ductile materials without the need for additional tapping operations.
