Standards Subsctiption may be the perfect solution.

Use this tolerance class for commercial external bolt threads. External thread minimum minor diameter [d 3min ]. Thread basic minor diameter [d 1D 1 ]. Internal thread minimum minor diameter [D 1min ]. The minimum diameter of a thread which is diameter of the root of a male thread or crest of a female thread.

Internal thread maximum pitch diameter [D 2max ]. Minor diameter tolerance of internal thread. External bolt thread root profile is given the “Definitions” section.

Need more than one copy? 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 External thread maximum truncation [C max ].

If the document is revised or amended, you will be notified by email. We have no amendments or corrections for this standard. The list of metric screw thread used in general engineering applications are given in the General Purpose Metric Screw Threads Table.


Your Alert Profile lists the documents that will be monitored. The user shall use 6g for bolts and 6H for nuts unless there is a specific requirement isk use other tolerance classes. Please first verify your email before subscribing to alerts. M10 x 1 6g. External thread minimum major diameter [d min ].

ISO – European Standards

In custom use, thread size, pitch and tolerance classes can be independently selected for custom engineering calculations.

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, please refer to pages – of Machinery’s Handbook, 30th.

Subscription pricing is determined by: The tolerance system refers to the basic profile according to ISO After coating, the actual thread profile shall not at any point transgress the maximum material limits for positions h or H.

External thread minimum pitch diameter [d 2min ]. The surface at the bottom of the groove connecting the adjacent flanks.

Use this tolerance class for commercial internal threads. For coated threads, the tolerances apply to the parts before coating, unless otherwise stated.

Major diameter tolerance of external thread. External thread minimum truncation [C min ].

Internal thread minimum major diameter [D min ]. You can download and open this file to your own computer but DRM prevents opening this file on another computer, including a networked server. This standard 95-2 also available to be included in Standards Subscriptions. Oso thread maximum pitch diameter [d 2max ]. Nominal Diameter x Pitch – Tolerance class for pitch diameter – Tolerance class for major diameter M10 x 1 5g 6g. In addition to basic size calculations of metric threads, tolerance calculations of different tolerance classes can be done according to ISO The maximum diameter of a uso which is diameter of the crest of a male thread or root of a female thread.

Details for the manufacture and use of gauges for checking ISO general-purpose metric screw threads are specified in the ISO Pitch diameter tolerance of internal thread.

For external bolt threads; The actual root contours shall not at any point transgress the basic profile. External thread maximum major diameter [d max ].
