Professional Applications & Engineering Value
Engineered for demanding industrial applications where exposure to moisture, chemicals, and corrosive agents is a constant challenge, this M4 flat head screw delivers unmatched durability. The 316 stainless steel material, combined with a passivated finish, provides a robust barrier against pitting and rust, significantly extending service life in marine, chemical processing, and food-grade equipment. The metric coarse thread (0.7mm pitch) and fully threaded design ensure rapid assembly and high clamp load retention, solving common issues of loosening under dynamic loads. Its flat head profile with a standard 90° countersink angle allows for a smooth, flush installation, preventing snagging and maintaining aerodynamic or hygienic surface integrity.
Specification Summary & Compliance
This screw features a Class 6g thread fit per ISO metric standards, ensuring precise dimensional tolerances for reliable performance. Manufacturing and material specifications conform to DIN 965. The product is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, confirming its suitability for use in environmentally conscious and regulated industrial markets.
