Professional Applications & Engineering Value
This M3 flat head screw is engineered to address common challenges in precision assembly, such as vibration loosening and corrosion-induced failure. The 18-8 stainless steel construction, combined with a passivated finish, provides exceptional resistance to oxidation and chemical exposure, extending service life in demanding settings like electronics enclosures, machinery, and automotive components. The partially threaded design with Class 6g thread fit ensures accurate alignment and reduces the risk of cross-threading, while the hex drive offers superior torque transmission for secure installations. Ideal for applications requiring flush mounting and reliable fastening, this screw minimizes protrusion and maintains structural integrity in metric coarse thread systems.
Specification Summary & Compliance
This fastener adheres to DIN 7991 (ISO 10642) specifications, ensuring precise dimensions including M3 thread size, 0.5mm pitch, and 22mm length with a Class 6g thread fit for standard metric tolerances. The partially threaded design features a minimum thread length of 12mm and a 90° countersink angle for consistent performance. It is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, confirming its suitability for industrial use without hazardous substances.
