METRIC THREAD SIZE AND TOLERANCE CALCULATOR (ISO M THREAD)
Details for the manufacture and use of gauges for checking ISO general-purpose metric screw threads are specified in the ISO If the document is revised or amended, you will be notified by email.
Your Alert Profile lists the documents that will be monitored. You may delete a document from your Alert Profile at any time.
Fasteners of property class 8. The list of metric screw thread used in general engineering applications are given in the General Purpose Metric Screw Threads Table. AmesWeb Calculators Screw Threads. Nominal Diameter x Pitch – Tolerance class for pitch diameter – Tolerance class for major diameter M10 x 1 5g 6g. External thread maximum minor diameter [d 3max ]. The tolerance system refers to the basic profile according to ISO Minor diameter tolerance of internal thread.
The maximum diameter of a thread which is diameter of the crest of a male thread or root of a female thread. For coated threads, the tolerances apply to the parts before coating, unless otherwise stated. The minimum diameter of a thread which is diameter of the root of a male thread or crest of a female thread.
For usage of the other classes, refer to ISO Pitch diameter tolerance of internal thread. M10 x 1 6g. The surface at the bottom of the groove connecting the adjacent flanks. External thread maximum truncation [C max ].
The user shall use 6g for bolts and 6H for nuts unless there is a specific requirement to use jso tolerance classes.
External thread minimum major diameter [d min ]. Standards Subscriptions from ANSI provides a money-saving, multi-user solution for accessing standards.
Subscription pricing is determined by: As the voice of the U. Use this tolerance class for commercial internal threads. Internal thread maximum pitch diameter [D 2max ]. Standards Subsctiption may be the perfect solution. Pitch diameter tolerance of external thread. 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 external ixo threads; The actual root contours shall not at any point transgress the basic profile. Tolerance Class for Bolt. You can download and open this file to your own computer but DRM prevents opening this file on another computer, including a networked server.
External thread minimum truncation [C min ]. General Engineering Use Custom Use. After coating, the actual thread profile shall not at any point transgress the maximum material limits for positions h or H.
We have no amendments or corrections for this standard. External thread maximum pitch diameter [d 2max ]. Use this tolerance class for commercial external bolt threads.
Tolerance class can be selected among the alternatives 6e, 6f, 6g ixo 4h for bolts and 5H, 6H, 7H and 6G for nuts. Internal thread minimum pitch diameter [D 2min ]. The theoretical profile of a screw thread in an axial plane defined by theoretical dimensions and angles common to internal and external threads.

Thread basic minor diameter [d 1D 1 ]. Major diameter tolerance of external thread.
External thread maximum major diameter [d max ]. Thread basic pitch diameter [d 2D 2 ]. External thread minimum pitch diameter [d 2min ]. Internal thread maximum minor diameter [D 1max ]. External bolt thread root profile is given the “Definitions” section.
