| How to represent the size of a metric thread |
 |
| A: Screw Type = Metric B: Outer diameter = 10mm C: Pitch = 1.5mm |
The first letter "M" indicates the type. → "metric thread".
The next number, 10, represents the outer diameter ( size diameter). → is "10mm".
"1.5" refers to the pitch. → "1.5mm".
 |
| A: Pitch (the distance between the threads. P) B: Outer diameter (The diameter that represents the size of the screw. Also known as " size diameter") |
There are also two ways to express pitch: namime and hosome.
If it is said that it is an ordinary M10, it is an expression that can be understood as 1.5.
