This number, when multiplied by a hundred, gives you the nominal tensile strength in newtons per millimetre squared. The digit following the decimal point, multiplied by ten, gives you the yield stress ration, or the percentage ratio between the lower yield stress and the nominal tensile strength. If you now multiply the first number by 10 times the second number you will arrive at the notional yield stress in newtons per millimetre squared. The main characteristic property of Nuts is the thread stripping strength (proof stress). The property classes of nuts are designated by a number which indicates the maximum appropriate property class of bolt with which they should be fitted. Therefore nut property classes are the same as the bolt designation initial number.

Internationally, mechanical stress is expressed in newtons per square area, in bolting N/mm2. Common practise overseas is to use the unit megapascal (MPa), which corresponds directly to N/mm2.
