Professional Applications & Engineering Value

These M1.7 metric flat head screws deliver exceptional engineering value in precision assembly applications where space constraints and reliability are critical. The zinc-plated steel construction provides essential corrosion protection for electronics, instrumentation, and small mechanical assemblies exposed to moderate environmental conditions. The JIS drive style ensures secure tool engagement, reducing cam-out risks during installation in delicate components. With Class 4h thread fit and fully threaded design, these screws maintain consistent clamping force in thin materials and plastic housings, preventing loosening under vibration. The 90° countersink angle creates flush surfaces in chamfered holes, essential for aerodynamic profiles and safety in consumer electronics, medical devices, and precision optical equipment where protrusions are unacceptable.

Specification Summary & Compliance
