Professional Applications & Engineering Value
This M4 brass flat head screw is engineered to address common industrial fastening challenges, such as corrosion in humid or chemical-exposed settings. Made from high-quality brass material, it resists rust and degradation, extending service life in electrical enclosures, machinery assemblies, and automotive components. The metric coarse thread with 0.7mm pitch and Class 6g fit ensures quick, secure installation without cross-threading, while the flat head profile and 90° countersink angle provide a flush finish for streamlined designs. With a 2.5mm hex drive, it enables efficient torque application, reducing assembly time and improving productivity in high-volume manufacturing.
Specification Summary & Compliance
This screw features precise metric dimensions including M4 thread size, 0.7mm pitch, and 10mm length, with Class 6g thread tolerance per ISO standards for consistent performance. It meets DIN 7991 specifications for flat head screws and is fully compliant with RoHS 3 (2015/863/EU) under exemption 6(a)-I for lead in alloys, as well as REACH (EC 1907/2006) regulations, ensuring environmental and safety adherence in industrial applications.
