Nut: hex

ISO 8673

ISO 8673 - Hexagon regular nuts (style 1) with metric fine pitch thread, product grades A and B

Paid access

Hexagon regular nuts, style 1, 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 ISO 4032: for a given diameter the hexagon body is identical and only the thread differs. Because the reduced thread height raises the risk of stripping, high nuts (style 2) to ISO 8674 are preferred. Covers M8 to M64 and includes both the preferred threads and the non-preferred threads.
