What is the standard pitch of M12 thread?

Thread Geometry – Metric Coarse

What is the most common metric thread pitch?

25 (fine) thread has a 1.25mm pitch. To simplify metric thread callouts, the international (ISO) standard for metric threads eliminates the pitch callout on coarse threads. For example, the thread “M10” automatically means a coarse pitch, while any added pitch callout, such as M10x1. 25, specifies a non-coarse pitch.

What is the standard metric thread pitch?

The common metric thread 10mm x 1.0 indicates a 10mm o.d. on the threaded portion and a thread pitch of 1.0mm, which is one thread every millimeter. Since there are 25.4 millimeters in 1 inch, that works out to 25.4 threads per inch. A 10mm x 1.25 is a course pitch.

What is difference between coarse pitch and fine 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 is the distance between the threads of a screw called?

Thread pitch
Thread pitch refers to the distance between threads and is expressed in millimeters. This measurement is taken along the length of the fastener.

What bolt thread is strongest?

Size for size, a fine thread is stronger than a coarse thread. This is both in tension (because of the larger stress area) and shear (because of their larger minor diameter). Because of the smaller pitch, they allow finer adjustments in applications that need such a feature.

How to determine thread pitch?

Measure an inch-long portion of the threaded area. Grab a ruler and lay it along the bolt or screw.

How do you calculate thread pitch diameter?

To calculate the pitch diameter, one must imagine a cylinder whose diameter exists at the point where the thread groove width and the thread crest width are both equal to one another and equal to half the nominal pitch of the thread. The diameter of this imagined cylinder is the pitch diameter.

What is M12 thread?

M12 is a matching coarse threaded nut (To avoid confusion, we always include the thread pitch for both coarse and fine metric fasteners.) If you normally work with inch fasteners, pitch can be a little confusing—pitch is the distance between adjacent threads. In the example above,…

How do you calculate metric thread pitch?

Figuring out Metric Thread Pitch Measure the distance from one thread to the next. Hold a ruler up against the threads, lengthwise. Determine the diameter and the length of the threaded area. Measure from the bottom of the head to the end of the threaded area in millimeters. Plug the measurements in to the standard metric form.
