Is 4mm the same as M4?
At the threaded bit, an M4 would be 4mm across.It’s a bit more accurate than that, everything from the diameter of the bolt without the thread to the shape of the thread is defined to a tolerance.

How are M4 bolts measured?
Do not measure the head of the bolt, measure the threaded part, outside of the threads. If your bolt is metric, then the diameter is stated using the letter “M”. For example, if your bolt has a diameter of 4mm then it is called an ‘M4 bolt’ if your bolt is imperial then it will be measured in inches.
What does M4 0.7 mean?
In metric nomenclature, an M4 x 0.7 cap screw has a 4 mm barrel and the pitch is 1 thread per 0.7 mm. (The term M4 x 0.7 is often shortened to just M4.)
What is the difference between M3 and M4 screws?

What size are M2 screws?
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. However, in practice the actual diameter might be between 1.9mm-2mm due to manufacturing tolerances.
What is a thread diameter?
Thread, Diameter, and Pitch
Major Diameter: The largest diameter of the thread of the screw or nut. The term “major diameter” replaces the term “outside diameter” as applied to the thread of a screw and also the term “full diameter” as applied to the thread of a nut.

Why are Allen bolts used?
The primary advantage of Allen bolts over hex bolts is that the tool used to do them up can be smaller than the head itself. So they are perfect for if you have a bolt that’s down inside a narrow opening. You can stick the Allen key down into the hole and do up the bolt.

What is M16 bolt size?
Metric bolts are made fractionally under their stated size, for instance an M16 bolt will have a shank diameter of typically 15.97mm. This means that a 16mm bolt will fit through a 16mm hole but to allow for misalignment between parts it is common practice to drill bolt holes slightly larger.
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.
