Technical standards and specifications of ASME B18.2.4.4M
This international standard defines the metric series of hex nuts, establishing strict requirements for geometric parameters, tolerances, and dimensional characteristics. Products supplied by EV Group China fully comply with these standards, ensuring precision accuracy of mating in critical machinery assemblies.
It is important to note that the presence of specifications described in the standard in the nomenclature does not always guarantee the immediate availability of the entire size range in stock. EV Group China experts recommend pre-coordinating the availability of specific nut sizes with our specialists to optimize delivery times and select the best solutions for your engineering tasks.
All hex nuts supplied by EV Group China undergo multi-stage quality control. Products must strictly comply with the geometric parameters of ASME B18.2.4.4M, as well as additional technological requirements set forth in Appendix I of this standard, which ensures the reliability of connections under conditions of high static and dynamic loads.
