What is the standard pitch of a bolt?
The finer the pitch, the closer the threads are together. These categories signify a specific measurement depending on the size of the thread. For example, for an M12 size screw with standard thread, the pitch will always measure 1.75mm, with fine thread the pitch will measure 1.5mm and extra fine will measure 1.25mm.
What is bolt thread pitch?
The thread pitch is the distance between threads expressed in millimetres (measured along the length of the fastener). For example a thread pitch of 1.5 means that the distance between one thread and the next is 1.5mm. In general smaller fasteners have finer thread so they have lower thread pitch.
What is the standard metric thread pitch?
Metric Thread Pitch Table
Bolt Diameter (mm) | Thread Pitch (mm) | |
---|---|---|
Standard | Extra or Super Fine | |
8 | 1.25 | – |
10 | 1.5 | 1 |
12 | 1.75 | 1.25 |
What is standard thread pitch?
approximately 14
The standard thread pitch is approximately 14 of the major diameter. The thread form is slightly modified to increase the minor diameter, and thus the strength of screws and taps.
What is M10 standard pitch?
5 (coarse) thread has a 1.5mm pitch, while an M10x1. 25 (fine) thread has a 1.25mm pitch. For example, the thread “M10” automatically means a coarse pitch, while any added pitch callout, such as M10x1.
What is the pitch of M6 thread?
Thread Geometry – Metric Coarse
Thread | Major Diameter | Pitch Diameter |
---|---|---|
M4 | 4.0 | 3.545 |
M4.5 | 4.5 | 4.013 |
M5 | 5.0 | 4.480 |
M6 | 6.0 | 5.350 |
What is coarse thread pitch?
Coarse threads are those with larger pitch (fewer threads per axial distance), and fine threads are those with smaller pitch (more threads per axial distance). Coarse threads have a larger threadform relative to screw diameter, where fine threads have a smaller threadform relative to screw diameter.

What does M12 mean?
6. Those are metric screw dimensions. M10 means a 10 millimeter outer diameter for the bolt or whatever piece it is; M12 means 12 millimeters. The part after the ‘x’ is the pitch — how many mm a thread is wide. To figure out which you have, you can measure the existing part with calipers and a thread gauge.
