ISO general purpose metric screw threads — Tolerances — Part 6: Limits of sizes for internal and external threads (fine and medium tolerance qualities, first and second choices)

This document specifies the limits of sizes for major, pitch and minor diameters of ISO general purpose metric screw threads (M) conforming to ISO 261 and having basic and design profiles in accordance with ISO 68-1. This document is applicable to the metric fastening screw threads with the ten tolerance classes (4H, 5H, 6H, 7H, 6G, 4h, 6h, 6g, 6f and 6e) recommended in ISO 965-1.

Foreword
ISO (the International Organization for Standardization) is a worldwide federation of national standards
bodies (ISO member bodies). The work of preparing International Standards is normally carried out through
ISO technical committees. Each member body interested in a subject for which a technical committee
has been established has the right to be represented on that committee. International organizations,
governmental and non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely
with the International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization.
The procedures used to develop this document and those intended for its further maintenance are described
in the ISO/IEC Directives, Part 1. In particular, the different approval criteria needed for the different types
of ISO document should be noted. This document was drafted in accordance with the editorial rules of the
ISO/IEC Directives, Part 2 (see www.iso.org/directives).
ISO draws attention to the possibility that the implementation of this document may involve the use of (a)
patent(s). ISO takes no position concerning the evidence, validity or applicability of any claimed patent
rights in respect thereof. As of the date of publication of this document, ISO had not received notice of (a)
patent(s) which may be required to implement this document. However, implementers are cautioned that
this may not represent the latest information, which may be obtained from the patent database available at
www.iso.org/patents. ISO shall not be held responsible for identifying any or all such patent rights.

Part 6:
Limits of sizes for internal and external threads (fine and
medium tolerance qualities, first and second choices)
1 Scope
This document specifies the limits of sizes for major, pitch and minor diameters of ISO general purpose
metric screw threads (M) conforming to ISO 261 and having basic and design profiles in accordance with
ISO 68-1.
This document is applicable to the metric fastening screw threads with the ten tolerance classes (4H, 5H, 6H,
7H, 6G, 4h, 6h, 6g, 6f and 6e) recommended in ISO 965-1.

4 Limits of sizes
4.1 General
The limits of sizes specified shall be derived from the fundamental deviations and tolerances specified in
ISO 965-1.
The limits of sizes for major, pitch and minor diameters of screw threads (M) have been calculated by the
following formulae, derived from the formulae provided in ISO 68-1 and ISO 965-1, and rounded to the third
decimal place.
Internal thread:
Major diameter D = D + EI
min
Pitch diameter D = D + EI = D – 0,649 519 P + EI
2 min 2
D = D + T
2 max 2 min D2
Minor diameter D = D + EI = D – 1,082 532 P + EI
1 min 1
D = D + T
1 max 1 min D1
External thread:
Major diameter d = d + es
max
d = d – T
min max d
Pitch diameter d = d + es = d – 0,649 519 P + es
2 max 2
d = d – T
2 min 2 max d2
Minor diameter d = d + es = d – 1,082 532 P + es
1 max 1
d = d – 0,866 025 404 P/2 + 2 C
3 max 1 max max
d = d – T – 0,866 025 404 P/2 + 0,250 P
3 min 1 max d2
Where es is a negative value.
For the symbols and their definitions see ISO 965-1.
The maximum major diameter of internal thread D is not specified.
max
Usually, the minimum major diameter of internal thread D and the maximum minor diameter of external
min
thread d are gauged by the crest diameter of GO thread gauges in accordance with ISO 1502.
1 max
For external threads, controlling the maximum minor diameter d and the minimum root radius R
1 max 1 min
ensures the conformity of the maximum minor diameter d .
3 max
Whether to measure the maximum and minimum minor diameters of external thread, d and d , shall
3 max 3 min
be decided according to the relevant threaded product documents. Unless specifically defined otherwise, it
is not necessary to carry out a measurement of the minor diameter d .
For the ten tolerance classes and nominal diameter ranges see Table 1.
