Professional Applications & Engineering Value
This M2.5 metric flat head screw is engineered to address common industrial challenges such as material fatigue, corrosion, and assembly precision. The zinc-plated steel material provides a durable barrier against rust and wear, making it suitable for electronics, machinery, and automotive components exposed to harsh conditions. Its fully threaded coarse thread design with a Class 6h fit ensures tight, reliable fastening that resists loosening under vibration, while the 90° countersink angle allows for seamless integration into panels and fixtures. By adhering to DIN 965 specifications, it delivers consistent dimensional accuracy, reducing the risk of misalignment and improving overall assembly efficiency in high-volume production environments.
Specification Summary & Compliance
This screw features a metric M2.5 x 0.45 mm coarse thread with a Class 6h tolerance for precise fit, a 25 mm length, and a flat head with standard profile. It is manufactured in compliance with DIN 965 standards and meets RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, ensuring safety and sustainability in industrial applications.
