Professional Applications & Engineering Value
This M30 flat head hex screw delivers critical engineering solutions where high tensile strength and reliable fastening are paramount. The black-oxide alloy steel construction provides superior corrosion resistance while maintaining the Class 10.9 mechanical properties essential for structural applications. The fully threaded metric coarse thread design ensures maximum thread engagement in heavy machinery, construction equipment, and industrial assemblies. The 60° countersink angle and flat head profile enable flush mounting in applications where surface protrusion is unacceptable. With Rockwell C32 hardness and precise DIN 7991 compliance, these screws withstand vibration, dynamic loads, and harsh operating conditions while maintaining joint integrity.
Specification Summary & Compliance
This metric flat head screw features M30x3.5 coarse threads with Class 6g thread fit tolerance ensuring precise mating compatibility. Manufactured to DIN 7991 specifications with full compliance to RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations. The fastener maintains Class 10.9 strength classification with verified 120,000 psi tensile strength and Rockwell C32 hardness for consistent performance in industrial applications.
