ISO metric trapezoidal screw threads — Tolerances — Part 2: Limits of sizes

This document specifies the limits of sizes for major, pitch and minor diameters of ISO metric trapezoidal screw threads (Tr) conforming to ISO 2902 and having basic and design profiles in accordance with ISO 2901. This document is applicable to the metric trapezoidal screw threads with the seven tolerance classes (7H, 8H, 9H, 7e, 8e, 8c and 9c) recommended in ISO 2903.

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.
Any trade name used in this document is information given for the convenience of users and does not
constitute an endorsement.

Part 2:
Limits of sizes
1 Scope
This document specifies the limits of sizes for major, pitch and minor diameters of ISO metric trapezoidal
screw threads (Tr) conforming to ISO 2902 and having basic and design profiles in accordance with ISO 2901.
This document is applicable to the metric trapezoidal screw threads with the seven tolerance classes (7H,
8H, 9H, 7e, 8e, 8c and 9c) recommended in ISO 2903.

4 Limits of sizes
4.1 General
The limits of sizes specified shall be derived from the fundamental deviations and tolerances specified in
ISO 2903.
The limits of sizes for major, pitch and minor diameters of screw threads (Tr) have been calculated by the
following formulae and rounded to the third decimal place.

Internal thread
Major diameter D = D + 2 a
4 min c
Pitch diameter D = D = D – 0,5 P
2 min 2
D = D + T
2 max 2 min D2
Minor diameter D = D = D – P
1 min 1
D = D + T
1 max 1 min D1
External thread
Major diameter d = d
max
d = d – T
min d
Pitch diameter d = d + es = d – 0,5 P + es
2 max 2
d = d – T
2 min 2 max d2
Minor diameter d = d – 2 a = d – P – 2 a
3 max 1 c c
d = d – T
3 min 3 max d3
Where es is a negative value.
For the symbols and their definitions see ISO 2903.
The maximum major diameter of internal thread D is not specified.
4 max
For the seven tolerance classes and nominal diameter ranges see Table 1.
