Professional Applications & Engineering Value

These M3 flat head screws are engineered to address common industrial fastening challenges, such as vibration loosening and corrosion-induced failure. The zinc-plated steel material offers a protective barrier against moisture and chemicals, extending service life in machinery, electronics, and automotive assemblies. With a coarse thread pitch of 0.5 mm and full threading, they deliver rapid installation and robust retention in softer materials or high-stress points. The slotted drive design allows for easy manual or automated driving, while the flat head profile ensures a smooth, flush finish that minimizes protrusion risks. Ideal for applications requiring DIN 963 compliance, these screws provide reliable performance in OEM production, maintenance repairs, and precision equipment where dimensional accuracy and thread fit are critical.

Specification Summary & Compliance

This product features precise metric dimensions: M3 thread size, 0.5 mm pitch, and 6 mm length, with Class 6h thread fit ensuring tight tolerances per ISO standards. Manufacturing adheres to DIN 963 and ISO 2009 specifications for flat head screw geometry, including a standard 90° countersink angle. The screws are fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, confirming the absence of restricted substances for safe use in various industrial sectors.
