Professional Applications & Engineering Value

These M4 flat head screws are engineered with zinc-plated steel to combat corrosion in humid or chemical-exposed settings, making them ideal for machinery, automotive, and electronic enclosures. The coarse 0.7mm pitch metric thread and Class 6h tolerance prevent cross-threading and ensure rapid assembly in high-volume production lines. With a Rockwell B71 hardness and 60,000 psi tensile strength, they maintain integrity under dynamic loads, reducing maintenance downtime. The fully threaded shank and standard flat head profile provide consistent clamping force, solving alignment issues in pre-drilled countersunk holes while meeting DIN 965 specifications for precision.

Specification Summary & Compliance

This screw adheres to ISO metric thread standards with M4 x 0.7mm coarse threading and Class 6h thread fit for dimensional accuracy. Manufacturing follows DIN 965 for flat head screw geometry, including 90° countersink angle. It is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring no restricted substances are used. The zinc-plated steel construction meets industrial durability requirements with a tensile strength of 60,000 psi.
