Metric machine screws from JLHY are precision-engineered fasteners for mechanical assemblies requiring reliable thread engagement with tapped holes or nuts. These screws comply with DIN 963, 964, 965, 966 (flat head, pan head, cheese head, and binding head respectively) and ISO 7045/7046/7047 standards, ensuring interchangeability with components manufactured to international specifications worldwide.

Machine screws differ fundamentally from sheet metal screws — they are designed for use with pre-tapped holes, producing precise and repeatable thread engagement. This precision makes them the standard choice for precision equipment assembly, electronics, switchgear, instrumentation, and any application where dimensional accuracy and consistent clamping force are non-negotiable.

JLHY's metric machine screws are produced from high-quality carbon steel with controlled hardness profiles. Thread tolerances meet ISO 965-1 6h standards for reliable preload prediction. Every production lot undergoes dimensional sampling per ISO 2859, with results documented and available upon request. Material certifications are provided for critical applications.

We offer a comprehensive range from M2 to M10 in all standard head types and drive configurations. Available materials include zinc-plated carbon steel, stainless steel A2 and A4 grades, brass, and nylon. Contact our engineering team for custom specifications and OEM production under your brand.
