External thread maximum minor diameter [d 3max ]. We have no amendments or corrections for this standard. Subscription pricing is determined by: If the document is revised or amended, you will be notified by email.

Internal thread minimum major diameter [D min ]. Thread basic pitch diameter [d 2D 2 ]. Internal thread minimum pitch diameter [D 2min ]. Internal thread maximum pitch diameter [D 2max ]. Tolerance Class for Nut. 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 After coating, the actual thread profile shall not at any point transgress the maximum material limits for positions h or H.

Pitch diameter tolerance of external thread. The minimum diameter of a thread which is diameter of the root of a male thread or crest of a female thread.

The theoretical profile of a screw thread in an axial plane defined by theoretical dimensions and angles common to internal and external threads. You can download and open this file to your own computer but DRM prevents opening this file on another computer, including a networked server.
