Professional Applications & Engineering Value
These M4 flat head screws deliver critical engineering solutions where surface flushness and structural integrity are paramount. The zinc-plated steel construction provides essential corrosion protection for industrial equipment, machinery assemblies, and outdoor applications. With fully threaded design and Class 6h thread fit, these metric fasteners ensure maximum thread engagement and vibration resistance in metal-to-metal and composite material joining. The 90° countersink angle and flat head profile enable seamless integration into pre-drilled surfaces, eliminating protrusions that could interfere with moving parts or aesthetic requirements. Ideal for automotive components, electrical enclosures, and manufacturing fixtures where DIN 963/ISO 2009 compliance is mandated for quality assurance.
Specification Summary & Compliance
This metric flat head screw features M4x0.7mm coarse threads with Class 6h thread fit tolerance per ISO standards. The 25mm length provides versatile fastening capability while maintaining dimensional accuracy per DIN 963/ISO 2009 manufacturing specifications. Full compliance with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations ensures suitability for global industrial markets and restricted substance requirements.
