High Hex Nuts

These standards from ANSI, ASME, ISO, SAE, and others address the materials, construction, and requirements for hex nuts for a variety of applications. This list addresses high hex nuts.

ISO 4033:2012

Hexagon high nuts (style 2) - Product grades A and B

ISO 4033:2012 specifies the characteristics of hexagon high nuts (style 2), with threads from M5 up to and including M36, with product grade A for threads of diameter less than or equal to M16 and product grade B for threads of diameter greater than M16.

ISO 8674:2012

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

ISO 8674:2012 specifies the characteristics of hexagon high nuts (style 2) with metric fine pitch thread, with nominal thread diameters from 8 mm up to and including 36 mm, with product grade A for sizes D 16 mm and product grade B for sizes D 16 mm. Coarse thread hexagon nuts, style 2, according to ISO 4033 are intended to be the first choice.
