EN ISO 7042:2012 PDF

Scope: This International Standard specifies the characteristics of prevailing torque type all-metal hexagon high nuts,with threads from M5 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, 10 and 12. 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.
