Nut: hex

ISO 8674

ISO 8674 - Hexagon high nuts (style 2) with metric fine pitch thread, product grades A and B

Paid access

Hexagon high nuts, style 2, with metric fine pitch thread, product grade A for threads up to and including M16 and product grade B above. The fine pitch counterpart of the high (style 2) ISO 4033 nut: for a given diameter the hexagon body and height are identical and only the thread differs. The extra height over the regular ISO 8673 nut gives more thread engagement and better stripping resistance, which is why style 2 is preferred for fine pitch threads. Covers M8 to M39 and includes both the preferred threads and the non-preferred threads.
