For usage of the other classes, refer to ISO For more information on Metric screw threads including thread form, definitions, limits and io for threads, standard series and combinations, thread designation, basic dimensions, dimensional effect of coating, formulas and details of MJ profile, please refer to pages din iso 965-1 96-51 Machinery’s Handbook, 30th.

The theoretical profile of a screw thread in an axial plane defined by cin dimensions and angles common to internal and external threads. Minor diameter tolerance of din iso 965-1 thread. The surface at the bottom of the groove connecting the adjacent flanks. External thread maximum truncation [C max ]. External thread minimum minor diameter [d 3min ]. Use this tolerance class for commercial external bolt threads. After coating, the actual thread profile shall not at any point transgress the maximum material limits for positions h or H.

The user shall use 6g for bolts and 6H for din iso 965-1 unless there is a specific requirement to use other tolerance classes.


ISO – Wikipedia

Pitch diameter tolerance of internal thread. Internal thread maximum pitch diameter [D 2max ]. M10 x 1 6g. Details for the din iso 965-1 and use of gauges for checking ISO general-purpose metric screw threads are specified in the ISO Tolerance Class for Nut.

Internal thread minimum pitch diameter [D 2min din iso 965-1.

Tolerance Class for Bolt. In addition to basic size calculations of metric threads, tolerance calculations of different tolerance classes can be done according to ISO din iso 965-1 The list of metric screw thread used in general engineering applications are given in the General Purpose Metric Screw Threads Table.

Pitch diameter tolerance of external thread. The minimum din iso 965-1 of a thread which is diameter of the root of a male thread or crest of a female thread.
