Product Details

Specification

Scope:

This Standard specifies hexagon nuts and hexagon thin nuts (hereafter generically referred to as "hexagon nuts") made of steel, stainless steel and non-ferrous metals.

If, in special cases, dimensions and product specifications other than those listed in this Standard are required, they shall be selected from existing Japanese Industrial Standards, for example JIS B 0205-4, JIS B 0209-1, JIS B 1021, JIS B 1052-2, JIS B 1052-6 and JIS B 1054-2 upon agreement between the purchaser and the manufacturer.

Annex JA gives specification of hexagon nuts not given in ISO 4032 to ISO 4036, and ISO 8673 to ISO 8675, Annex JB gives specifications of steel nuts of property classes 4 t TO 10 T.

NOTE: The International Standards corresponding to this Standard and the symbol of degree of correspondence are as follows.

ISO 4032 : 2012 Hexagon regular nuts (style 1) - Product grades A andB

ISO 4033 : 2012 Hexagon high nuts (style 2) - Product grades A and B

ISO 4034 : 2012 Hexagon regular nuts (style 1) - Product grade C

ISO 4035 : 2012 Hexagon thin nuts chamfered (style 0) - Product grades A and B

ISO 4036 : 2012 Hexagon thin nuts unchamfered (style 0) - Product gradeB

ISO 8673 : 2012 Hexagon regular nuts (style 1) with metric fine pitch thread - Product grades A and B

ISO 8674 : 2012 Hexagon high nuts (style 2) with metric fine pitch thread - Product grades A and B

ISO 8675 : 2012 Hexagon thin nuts chamfered (style 0) with metric fine pitch thread - Product grades A and B (Overall evaluation: MOD)

In addition, symbols which denote the degree of correspondence in the contents between the relevant International Standards and JIS are IDT (identical), MOD (modified), and NEQ (not equivalent) according to ISOI lEC Guide 21-1.
