Professional Applications & Engineering Value
This M4 flat head screw in 316 stainless steel with a passivated finish addresses critical challenges in demanding sectors like marine, chemical processing, and outdoor equipment, where corrosion resistance is paramount. The fully threaded design and Class 6g thread fit ensure tight, reliable connections in metric coarse thread applications, reducing the risk of vibration-induced failure. Its undercut flat head and 2.5 mm hex drive facilitate quick, flush installations, minimizing protrusion and enhancing aesthetic integrity. Engineered for industrial screws requiring high tensile strength and consistent performance, this component delivers long-term value by withstanding extreme conditions while maintaining RoHS and REACH compliance for safe, sustainable use.
Specification Summary & Compliance
This screw adheres to precise dimensional tolerances, including a head diameter tolerance of -0.127 to 0.127 mm and Class 6g thread fit per metric standards. It is manufactured with a right-hand thread, M4 x 0.7mm coarse pitch, and fully threaded length of 12 mm. Compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, it meets stringent environmental and safety requirements for industrial applications.
