Professional Applications & Engineering Value
This M3 flat head screw is engineered from 18-8 stainless steel with a passivated finish to resist oxidation and chemical exposure, making it suitable for demanding sectors like automotive, electronics, and machinery. The Class 6g thread and coarse pitch provide excellent tolerance control, reducing cross-threading risks during high-speed assembly. Its drilled spanner drive ensures torque resistance in confined spaces, while the fully threaded design enhances grip in brittle or thin materials. Ideal for applications requiring flush surfaces and reliable fastening under vibration, this screw addresses common issues of loosening and corrosion in industrial settings.
Specification Summary & Compliance
The screw features a Metric M3 x 0.5mm coarse thread with Class 6g fit tolerance, ensuring precise dimensional accuracy. It complies with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, confirming it is free from hazardous substances. Manufacturing adheres to standard metric specifications for thread form and head dimensions, supporting consistent performance in regulated industries.
