Technical specifications and scope of the EN ISO 14579 standard
This technical manual systematizes the requirements for cheese head screws equipped with a hexalobular (TORX) socket. The standard covers hardware products of product grades A and B with a metric thread range from M2 to M20. These fasteners provide optimal torque transmission and high reliability of threaded connections in mechanical engineering and instrumentation.
EV Group China engineers note that when designing assemblies that require deviations from the basic parameters of this standard, one should be guided by related international specifications, including ISO 261, ISO 888, and ISO 898-1, which regulate thread tolerances and the mechanical properties of fasteners.
