Already Subscribed isp this document. Subscription pricing is determined by: Internal thread maximum pitch diameter [D 2max ]. External bolt thread root profile is given the “Definitions” section. The theoretical profile of a screw thread in an axial plane defined by theoretical dimensions and angles common to internal and external threads.
The list of metric screw thread used in general engineering applications are given in the General Purpose Metric Screw Threads Table.
Metric Thread Size and Tolerance Calculator
In addition to basic size calculations of metric threads, tolerance calculations of different tolerance classes can be done according to ISO 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.
In custom use, thread size, pitch and tolerance classes can be independently selected for custom engineering calculations. Tolerance Class for Bolt. External thread maximum major diameter [d max ].
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 Standards Subsctiption may be the perfect solution.
This standard is also available to be included in Standards Subscriptions. Minor diameter tolerance of internal thread. You can download and open this file to your own computer but DRM prevents opening this file on another computer, including a networked server. Details for the manufacture and use of gauges for checking ISO general-purpose metric screw threads are specified in the ISO Major diameter tolerance of external thread.
