How are metric screws sizes?
Metric nuts and bolts are commonly referenced using 'M' sizes, for example: M3, M8, M12. But the size of a metric fastener is more accurately specified using diameter, pitch and length dimensions, in millimeters. For nuts the size dimensions used are simply diameter and pitch.

Is M10 the same as 10mm?
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.
How do you read screw sizes?
A screw for wood is sized by two distinct numbers, first is the gauge of the screw which is the diameter. This means, the larger the number the larger the diameter. Therefore, a number 12 screw is larger than a number 4 screw.
What is M2 screw size?
2mmM2 screws are typically used in the manufacture of small items of electrical equipment, laptops, cameras and mobile phones. The “M” designation for metric screws indicates the outer diameter of the screw in millimetres, so for an M2 screw, the outer diameter is 2mm.

Is M3 a 3mm?
Specifically, the screw type is M3-0.50, meaning the threads of the screws are 0.50mm apart. Normally, M3 refers only to the reference diameter of 3 millimeters, and other industries may use coarser 0.70mm threads - but in the context of PCs, 0.50mm threads are implied.
What is a number 8 screw in mm?
GENERAL SIZE - 8 common lengths from 4mm to 20mm, generally universal. The screw sorting kits come in different sizes to meet your wood and various hardware locking needs.
