This example illustrates how a coarse threaded screw may appear… M12 x 25 = 12 mm diameter, coarse thread is assumed (1.75 mm), 25 mm long. M12 is a matching coarse threaded nut. (To avoid confusion, we always include the thread pitch for both coarse and fine metric fasteners.)
What does M12 mean on a bolt?
The first half (M12), is the size measurement (metric) taken across the outside diameter of the thread (which in this case is 12mm). The second half is the thread pitch, which is the measurement of threads/inch (which in this case is 1.75).
What does the term M12 mean?
M12 is a 12mm diameter thread. You have to be sure the thread pitch measured in threads per millimeter (1.5 here) is the same as what u need.
What is M12 thread size?
ISO Metric Machine Screw Thread Dimensions

|---|---|---|
| M8 | 8.0 | 1.25 |
| M10 | 10.0 | 1.50 |
| M12 | 12.0 | 1.75 |
| M14 | 14.0 | 2.00 |
What does M stand for in bolt sizes?
Taking a closer look at this description, let’s explore its meaning: M = This designates the fastener is a metric size. 10 = The nominal diameter in millimeters. 1.0 = The thread pitch, or distance between threads, in millimeters. 20 = The fastener’s length, in millimeters.
What is M12 inches?

What is the difference between M12 and M18?
M18™ is the other most common battery size. Whereas M12™ is ideal for tools that require less power, the Milwaukee® battery M18™ is best for tools needed for heavier-duty jobs that require more power. This 18-volt battery features a larger design and base, which means it is a little heavier.
Are m10 and 3/8 the same?
As George says the CG-5 does use the metric 10 x 1.5. 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..
What thickness is M12?
M12 bolts are a metric sized bolt with a 12mm thread diameter.
Is M4 the same as 4mm?
At the threaded bit, an M4 would be 4mm across.
How do you read thread sizes?
Thread sizes are given in nominal sizes, not in the actual measurement. The exact measurement is slightly below the named or nominal size. For example, a 6mm bolt may measure 5.8mm or 5.9mm, but it is called 6mm bolt. It is also common to use “M” before the bolt size, such as M6 for a 6mm bolt.
How do you identify metric threads?
Metric threads are measured by their pitch. That is the distance from the crest of one thread to the crest of the next measured in millimetres. The pitch of a metric thread can be checked by direct measurement with a metric rule. Imperial threads have their pitch measured indirectly as a given number of teeth per inch.
What size head does an M12 bolt have?
Metric Hex Bolt Dimensions
| NOMINAL SIZE (D) | BODY DIAMETER | HEAD THICKNESS |
|---|---|---|
| m12 | 12.00 | 7.76 |
| m14 | 14.00 | 9.09 |
| m16 | 16.00 | 10.32 |
| m20 | 20.00 | 12.88 |
Is M10 a 10mm?
M10 (10mm) Thread Size (T) 6.6mm Head Length (H)
What do letters on bolts mean?
You can usually figure out the grade, or strength, of a bolt by looking at the markings on its head. English bolts (U.S.S. or S.A.E) are categorized by grade, from grade 2 to grade 8, where the grade represents inch strength. The higher the grade, the stronger the bolt.
What’s the difference between M10 and M12?
The only difference between the M10 and M12 is the external appearance.
