    Abstract - (Show below) - (Hide below)

    Defines the characteristics of prevailing torque type all-metal hexagon nuts, of style 2, having threads from M5 to not exceeding M36, in product grade A for threads to not exceeding M16 and product grade B for threads above M16 and with property class 9.

    Scope - (Show below) - (Hide below)

    This International Standard specifies the characteristics of prevailing torque type all-metal hexagon nuts, of style 2, with threads from M5 up to and including M36, in product gradeA for threads up to and including M16, and product gradeB for threads over M16, and with property class 9.

    NOTE1 The dimensions of the nuts, with the exception of the dimensions mw and hmax, correspond to those given in ISO4033.

    NOTE2 Nuts of property classes 5, 8, 10 and 12 are dealt with in ISO7042.

    If other specifications are required, they can be selected from existing International Standards, for example ISO261, ISO724, ISO898-2, ISO965-2, ISO2320 and ISO4759-1.
