Professional Applications & Engineering Value

These M1.7 metric flat head screws address critical needs in precision assembly, where space constraints and vibration resistance are paramount. The zinc-plated steel material combats rust in humid or outdoor settings, while the Class 4h thread fit and coarse pitch (0.35mm) enhance grip in soft materials like plastics or thin metals. With a JIS No. 0 drive and fully threaded 3mm length, they provide consistent torque transfer and full-length holding power in electronics, automotive controls, or miniature machinery. The 90° countersink angle ensures a seamless finish, preventing snagging and improving aesthetics in consumer devices and industrial equipment.
