Professional Applications & Engineering Value
This M4 brass flat head screw with a hex drive is engineered to address common industrial challenges such as corrosion, vibration loosening, and assembly efficiency. The brass material provides inherent resistance to rust and galvanic corrosion, making it suitable for electrical components, marine equipment, and plumbing systems. Its fully threaded coarse pitch design ensures rapid installation and robust grip in soft materials like wood or plastic, while the flat head profile sits flush for streamlined surfaces. With a 2.5mm hex drive, it enables high-torque applications without cam-out, reducing downtime in production lines. Ideal for industrial fastening in machinery, automotive, and electronics, this screw combines durability with compliance to meet rigorous engineering standards.
Specification Summary & Compliance
This product adheres to DIN 7991 specifications, with precise metric thread dimensions including M4 size, 0.7mm pitch, and Class 6g tolerance for consistent fit. It is fully compliant with RoHS 3 (2015/863/EU) under exemption 6(a)-I for lead in brass alloys and REACH (EC 1907/2006) regulations, ensuring environmental safety and material integrity.
