JLHY's metric hex nuts are manufactured to DIN 934 / ISO 4032 standards for consistent, reliable thread engagement with metric bolts across a vast range of applications. The standard hexagonal profile provides a large bearing surface for secure tightening with standard wrenches and sockets, while the controlled thread geometry ensures smooth assembly and reliable torque-to-clamp relationships.

Produced from medium carbon steel with zinc plating for corrosion resistance in indoor and general outdoor use. Available in Grade 8 and Grade 10 to match corresponding bolt grades for properly rated structural or mechanical joints. JLHY maintains tight tolerances on thread pitch, major diameter, and effective thread length to ensure reliable engagement.

We also offer nylon insert lock nuts (Nyloc) and all-metal lock nuts for vibration-prone applications. Full traceability documentation is available. Contact JLHY for competitive pricing on metric hex nuts in any quantity.
