What is an M10 screw?
If the size is M10 x 25, that would mean that the diameter is 10 mm. Since there is no thread pitch listed, the fastener is assumed to have a coarse thread. The 25 indicated a length of 25 mm. A matching nut would be labeled M10, which also doesn’t require a thread pitch since it’s a course thread fastener.
What diameter is M12?
M12 bolts are a metric sized bolt with a 12mm thread diameter.
What size is M10 bolt in inches?
Table 3.
| Metric | Closest Inch |
|---|---|
| M8-1.25 | 5/16-18 (Smaller) |
| M10-1.5 | 3/8-16 (Smaller) |
| M12-1.75 | 1/2-13 (Larger) |
| M14-2.0 | 9/16-12 (Larger) |
Are M10 and 3/8 the same?
That said, they are very close, the 3/8″ bolt is about 0.019″ smaller and the pitch’s are very close so the 3/8 -16 bolt will thread in the 10mm x 1.5 but the 10 x 1.5 bolt will not fit the 3/8 but..

How do you tell what size a bolt is?
To measure the diameter of screws and bolts, you measure the distance from the outer thread on one side to the outer thread on the other side. This is called the major diameter and will usually be the proper size of the bolt.
How do you calculate threads per inch?
As the name suggests, TPI is measured by counting the number of thread peaks along a 1 inch length. The TPI measurement is then often affixed to the diameter of the thread to form a common imperial thread size, e.g. ‘1/4-20’, which would denote a ¼ inch diameter, and 20 threads per inch.
