The ISO metric screw thread family is a series of general-use, 60° straight threads. It is the most commonly used worldwide thread system. It was one of the first topics standardized by the ISO committee as early as 1947 and is still used today.
ISOStandards
Several ISO standards define together the ISO metric thread system:

Limits
Charts for the allowed range of pitch, major and minor diameters for classes 6H and 6g.
The values are calculated from the definitions of ISO 965-1.
They have limited use since they provide data only for the default classes.
Designations
The description always begins with a capital M, followed by the nominal thread diameter in millimeters. For example, M8 is a thread with a nominal diameter of 8 mm (0.315″). If no characters follow the M and diameter, it means that all the other parameters are according to the default as defined in ISO 965-1:
Pitch: Designated by “X P“. For example, M8 X 0.75 means an 8 mm (0.315″) thread with a pitch of 0.75 mm (0.03″ or 34 TPI). If the “X P” is omitted, the pitch is defined by the Coase Pitch Series according to ISO-261.
Number of starts: Designated by “Ph”. For example, M8 X Ph2.25P0.75. In this case, 2.25 mm is the lead, and 0.75 mm is the pitch. Ph must be a multiple of P since the number of starts equals Ph/P. For this example, the number of starts is 3. If Ph is omitted, the thread has a single start.
Class: The class appears after the pitch. It is preceded by a “-” and consists of two or four characters. For example, M8 X 0.75 – 5g6g.
Small letters represent external threads, while capital letters represent internal threads.
Two charters long class mean that the class is valid for both the pitch and major/minor diameters.
Four long charters mean a separate class for the pitch diameter (The first two characters) and major/minor diameters (The first two characters).
For detailed explanations about classes, see the class section below.
If the class is omitted, the default class is used. (See above table)
Thread Direction: The direction appears after the class and is preceded by a “-“. If omitted, the direction is right hand. If “- LH” appears, it designates a left-hand thread. For example, M8 X 0.75 – 5g6g – LH is a left-hand thread designation.
Standard ISO metric series
The ISO Metric Thread System consists of two series:
The basic dimensions are nominal dimensions of a metric thread profile without allowance and tolerances (The thread class defines that). They are based on standard ISO 68-1. The basic dimensions can be used for design. However, for manufacturing and machining, you need the allowable rage of each dimension. This data can be found in ISO 951-1 or in the Limits and Dimensions section below. All these parameters are derived from simple formulas based on the thread’s nominal diameter and pitch.

To manufacture or measure a thread, one has to know the maximum and minimum permissible values of the basic dimensions. These values are calculated according to the thread class (See below). To understand classes, you first need to understand the terms Allowance(Sometimes referred to as deviation) and Tolerances. The below data and explanations are based on ISO 965-1
Definition of terms:
Allowance (Deviation): The minimum permissible distance between the basic and actual profile.
Tolerance: The width of the tolerance field of a diameter on the actual thread profile. (Pitch, Major & Minor diameters)
A small allowance means that the assembly of a male and female thread will be harder, but after assembly, there will be less freedom of movement.
A large allowance means that the assembly of a male and female thread will be easier, but after assembly, there will be more freedom of movement.
The allowance size does not influence a thread’s production difficulty or price.
A wide tolerance is easier and cheaper to produce but yields a larger spread between threads.
A narrow tolerance is challenging to produce and more expensive but yields a smaller spread between threads.
Metric Thread Classes
The class is written after the pitch. It is preceded by a “–” and consists of two or four characters. For example, for “M8 X 0.75 – 5g6g“, the class is 5g6g. The class defines the Deviation (allowance) and tolerance of the thread.
Small letters represent external threads, while capital letters represent internal threads.
Two charters long class mean that the class is valid for both the pitch and major/minor diameters.
Four long charters mean a separate class for the pitch diameter (The first two characters) and major/minor diameters (The last two characters).
If the class is omitted, the default class is used.
The engineer can select any class for the male and female threads to achieve his design goals. However, ISO 965-1 recommends limiting the choice according to a chart of “Recommended Classes”.
The choice of the recommended class is made according to two parameters:
Tolerance Quality:
F – Fine: for precision threads, when a minimal variation of fit is needed.
M – Medium: for general use.
C – Coarse: for cases where manufacturing difficulties can arise, for example, when threading hot-rolled bars and long blind holes.
Blue Background– Default Classes Green Background– First Choice Classes. Yello Background – Second Choice Classes.

Metric Thread Allowance (Deviations)
The allowanceEL for internal threads and es for external threads is derived from the class. The approximate allowance can be calculated according to the below formulas:
Unfortunately the above formulas are approximations only. The formal values must be obtained from ISO 965-1 or from the below chart

Metric ThreadTolerances
The tolerances TD for internal threads and Tdfor external threads is derived from the class. The approximate tolerances can be calculated according to the below formulas.
The above formulas are approximations. For the formal values, use the below chart or standard ISO 965-1
Metric Thread Tolerances Chart
Type your thread description in the Search Box.
Values are in Microns.
For millimeters divide by 1,000. For Inches divide by 25,4000.

Metric Thread limitsCalculations
Once the Td, TD, es & EL values are known the final limits can be calculated according to the below formulas.
The Metric thread standard ISO 965-2 provides the limits only for classes 6H & 6g*. In all other cases, calculations must be made manually according to the below formulas or by our Threading Calculator
* For threads over 1.4 mm and classes 5H & 6h for threads up to and including 1.4 mm
