3、al hexagon nuts, style 2, with metric fine pitch thread - Property classes 8,10 and 12 1 Scope This International Standard specifies the characteristics of prevailing torque type all-metal hexagon nuts, of style 2, with metric fine pitch thread, with nominal thread diameters dfrom 8 mm up to and inc
4、luding 36 mm, in product grade A for sizes d up to and including 16 mm and product grade B for sizes d above 16 mm, and with property classes 8, 10 and 12. NOTE -The dimensions of the nuts with the exception of the dimensions Q and IJ, correspond to those given in IS0 8674. If other specifications a
5、re required, they should be selected from existing International Standards, for example IS0 261, IS0 965-2, IS0 2320 and IS0 4759-l. 2 Normative references The following standards contain provisions which, through reference in this text, constitute provisions of this International Standard.
