Professional Applications & Engineering Value
These M3 metric screws with zinc-plated steel construction address critical challenges in precision assembly applications. The Torx T10 drive system delivers exceptional torque transfer efficiency, eliminating fastener damage common in high-cycle manufacturing. With fully threaded coarse pitch (0.5mm) design and Class 6g thread fit, these fasteners provide rapid installation and vibration resistance in electronics, machinery, and automotive components. The rounded pan head profile offers both aesthetic appeal and functional clearance, while the corrosion-resistant plating ensures long-term reliability in humid or chemically exposed environments. Engineered to ISO 7045 specifications, these screws deliver consistent dimensional accuracy for automated assembly systems.
Specification Summary & Compliance
This M3 x 0.5mm x 4mm fastener maintains Class 6g thread tolerance per metric standards with coarse thread spacing for optimal engagement. Manufacturing complies with ISO 7045 dimensional requirements for pan head screws. Environmental compliance is verified through RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) certifications, ensuring restricted substance adherence. The right-hand thread direction and fully threaded configuration provide standardized installation compatibility across industrial applications.
