Professional Applications & Engineering Value

This M4 flat head screw is engineered to address common industrial challenges such as vibration loosening and corrosive degradation. Made from 18-8 stainless steel with a passivated finish, it resists rust and chemical exposure, making it suitable for outdoor equipment, machinery, and electronics. The coarse metric thread (0.7mm pitch) and Class 6g thread fit provide quick assembly and high clamping force, reducing installation time while maintaining joint integrity. Its fully threaded body and flat head design ensure a secure, flush fit in countersunk holes, ideal for applications where protrusion is not acceptable. By adhering to DIN 963 and ISO 2009 standards, this screw delivers consistent performance in metric fastener systems, enhancing reliability in manufacturing and maintenance operations.
