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. Tolerance Class for Bolt.

Standards Subsctiption may be the perfect solution. This standard is also available to be included in Standards Subscriptions. Thread basic pitch diameter [d 2D 2 ]. Already Subscribed to this document. Minor diameter tolerance of internal thread.

General Engineering Use Custom Use.


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 Height of fundamental triangle [H].

Internal thread maximum minor diameter [D 1max ]. External thread maximum minor diameter [d 3max ]. The theoretical profile of a screw thread in an axial plane defined by theoretical dimensions and angles common to internal and external threads. Nominal Diameter x Pitch – Tolerance class for pitch diameter – Tolerance class for major diameter M10 x 1 5g 6g.


External thread maximum truncation [C max ]. Proceed to Checkout Continue Shopping.

We have no amendments or corrections for this standard. Pitch diameter tolerance of internal thread.

Internal thread minimum pitch diameter [D 2min ]. External bolt thread root profile is given the “Definitions” section.


Internal thread minimum major diameter [D min ]. The minimum diameter of a thread 9652 is diameter of the root of a male thread or crest 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.

The tolerance system refers to the basic profile according to ISO In custom use, thread size, pitch and tolerance classes can be independently selected for custom engineering calculations. The user shall use 6g for bolts and 6H for nuts unless there is a specific requirement to use other tolerance classes.
