Professional Applications & Engineering Value

These M1.6 metric flat head screws deliver critical engineering solutions where space-constrained applications demand reliable fastening performance. The zinc-plated steel construction provides essential corrosion protection for electronics assembly, automotive components, and precision instrumentation. The fully threaded coarse spacing design ensures maximum thread engagement in thin materials, while the 90° countersink angle enables flush mounting in pre-drilled surfaces without protrusion. Engineered with JIS No. 0 drive compatibility, these screws prevent cam-out issues during high-volume installation. The combination of 60,000 psi tensile strength and Rockwell B71 hardness makes them ideal for vibration-resistant applications where mechanical failure is not an option.
