Standards Subsctiption may be the perfect solution. After coating, the actual thread profile shall not at any point transgress the maximum material isp for positions h or H. External bolt thread root profile is given the “Definitions” section. The maximum dib of a thread which is diameter of the crest of a male thread or root of a female thread.


The list of metric screw thread used in general engineering applications are given in the General Purpose Metric Screw Threads Table. This standard is not included in any packages. For usage of the other classes, refer to ISO Pitch diameter tolerance of external thread.

Major diameter tolerance of external thread. General Engineering Use Custom Use. External thread minimum pitch diameter [d 2min ].

Metric Thread Size and Tolerance Calculator

Your Alert Profile lists the documents that will be monitored. In general engineering use, calculations can be done by selecting a standard metric thread size from the list which contains metric thread sizes in the diameter range from 1. For more information on Metric screw threads including thread form, definitions, limits and fits for threads, standard series and combinations, thread designation, basic dimensions, dimensional effect of coating, formulas and details of MJ profile, di refer to pages – of Machinery’s Handbook, 30th.

External thread minimum major diameter [d min ]. Metric thread size and tolerance calculator was developed to calculate major, minor and pitch diameters of the external bolt and internal nut metric threads according to ISO Subscription pricing is determined by: Tolerance Class for Nut.

Use this tolerance class for commercial internal threads.

Add to Alert PDF. In custom use, thread size, pitch and tolerance classes can be independently selected isp custom engineering calculations. In addition to basic size calculations of metric threads, tolerance calculations of different tolerance classes can be done according to ISO You may delete a document from your Alert Profile at any time.
