Professional Applications & Engineering Value

This M3 flat head screw delivers exceptional engineering value through its zinc-plated alloy steel construction and Torx T10 drive system. The combination provides superior corrosion protection while enabling high-torque installation without damaging the drive recess. The fully threaded design with coarse 0.5 mm pitch ensures rapid assembly and secure fastening in materials where vibration resistance is critical. The 90° countersink angle and flat head profile create flush surfaces ideal for applications requiring aerodynamic profiles or smooth finishes. These industrial fasteners solve common challenges of stripped drive heads, corrosion failure, and inconsistent thread engagement, making them perfect for automotive assemblies, machinery enclosures, and electronic equipment where Class 8.8 strength and regulatory compliance are mandatory.

Specification Summary & Compliance

This metric fastener maintains precise Class 6h thread fit tolerances and ISO 14581 manufacturing specifications. The right-hand threaded M3 x 0.5 mm screw with coarse thread spacing ensures compatibility with standard metric components. Full compliance with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations guarantees environmental safety, while the Rockwell C22 hardness rating confirms material integrity for demanding applications.
