Automatically build standard products in SOLIDWORKS with TSFP.

Paid access

Hexagon regular nuts, style 1, with metric fine pitch thread: the ISO 4032 nut with the same hexagon and height, only the thread differs. Product grade A for threads up to and including M16 and product grade B above. 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.
