Minor diameter tolerance of internal thread.

The surface at the top of the ridge connecting its two flanks. The maximum diameter of a thread which is diameter iso 965-1 the crest of a male thread or root of a female thread. For coated threads, the tolerances apply to iso 965-1 parts before coating, unless otherwise stated.

External thread maximum truncation [C max ]. General Engineering Use Custom Use. External thread minimum iso 965-1 [C min ]. Thread basic pitch diameter [d 2D 2 ]. Use this tolerance class for commercial external bolt threads.

For external bolt threads; The actual root contours shall not at any point iso 965-1 the basic profile. Major diameter tolerance of external thread. Internal thread maximum pitch diameter [D 2max ]. In general engineering use, calculations can be done by selecting a standard metric 9655-1 size from the list which contains metric oso sizes in the diameter range from 1.

Pitch diameter tolerance of internal thread. Internal thread maximum minor diameter [D 1max iso 965-1.


Tolerance Class for Nut. The minimum diameter of a thread which is diameter of the root of a male thread ios crest of a female thread. Use this tolerance class for commercial internal threads. Nominal Diameter iso 965-1 Pitch – Tolerance class for pitch diameter – Tolerance class for major diameter M10 x 1 5g iso 965-1. Fasteners of property class 8.
