Prevailing torque type hexagon regular nuts (with non-metallic insert) - Property classes 5, 8 and 10 (ISO 7040:2012)
N EN ISO 7040
Annotation
This International Standard specifies the characteristics of prevailing torque type hexagon regular nuts (with non-metallic insert), with threads from M3 up to and including M36, in product grade A for threads up to and including M16 and product grade B for threads above M16, and with property classes 5, 8 and 10.
NOTE The dimensions of the nuts correspond to those given in ISO 4032 plus prevailing torque feature.
If other specifications are required, they can be selected from existing International Standards, for example ISO 261, ISO 724, ISO 898-2, ISO 965-2, ISO 2320 and ISO 4759-1.
