Professional Applications & Engineering Value

These M4 flat head screws are engineered to solve critical fastening challenges in industrial assembly. The zinc-plated steel construction provides a protective barrier against oxidation and chemical exposure, significantly extending component life in machinery, electrical enclosures, and automotive applications. The fully threaded design and coarse thread pitch ensure maximum thread engagement in both soft and hard materials, preventing loosening under vibration while enabling faster installation. With DIN 965 compliance guaranteeing dimensional accuracy and the flat head profile creating flush surfaces, these metric screws deliver reliable performance in applications where space constraints and aesthetic finish are equally important.

Specification Summary & Compliance

This fastener features Class 6h thread fit tolerance per ISO metric standards, ensuring precise threading compatibility. Manufacturing specifications strictly adhere to DIN 965 standards for dimensional accuracy, including the 90° countersink angle and standardized head dimensions. The product is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, confirming the absence of restricted hazardous substances. The combination of 60,000 psi tensile strength and Rockwell B71 hardness validates the mechanical performance for demanding industrial applications.
