International Metric Thread (IMT) is a standardized system for screw threads that uses the metric measurement system. Defined by ISO 68-1, it features a triangular profile with a 60-degree angle and is characterized by its pitch, which is the distance between adjacent threads, measured in millimeters. IMT is widely used in various applications, including machinery and engineering, due to its uniformity and compatibility across different countries and industries. This standardization helps ensure interoperability and simplifies manufacturing processes.

How is metric thread pitch measured?

Metric thread pitch is measured directly from crest to crest of the thread form. For example the distance from crest to crest of a M8 x 1.25 MM thread would be 1.25 MM. Another way to measure it would be linear travel per rotation, in which case a M8 x 1.25 MM thread would travel 1.25 MM each rotation.


Are all metric units also system international?

No, not all metric units are part of the International System of Units (SI). The SI is a coherent system of units derived from the metric system, but it is more specific and defined, and not all metric units are included in the SI.


What does m mean in m6 thread?

In an M6 thread, the "M" stands for metric, indicating that the thread is measured in millimeters. The "6" signifies the nominal diameter of the screw or bolt, which is 6 millimeters. This designation is part of a standardized system used for metric fasteners, ensuring compatibility and consistency across different applications.


What does the -6h mean after the metric thread callout?

The "-6h" in a metric thread callout indicates the tolerance class of the thread. The "6" refers to the nominal diameter of the thread, while the "h" denotes the tolerance grade, which specifies the allowable deviations from the nominal dimensions for the internal or external thread. In this case, it signifies a medium tolerance for fit, commonly used for standard applications. This classification ensures compatibility and proper functioning of threaded components.
