Nut: hex

ISO 4033

ISO 4033 - Hexagon high nuts (style 2), product grades A and B

Paid access

Hexagon high nuts, style 2, product grade A for threads up to and including M16 and product grade B above. The high (style 2) counterpart of the regular ISO 4032 nut: for a given diameter the hexagon body is identical and only the height is greater, which increases thread engagement and stripping resistance. Covers metric coarse pitch from M5 to M39 and includes both the preferred threads and the non-preferred threads M7, M14, M18, M22, M27, M33 and M39.
