How do you tell what M size a bolt is?
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. for example if it measures 1/4″, then the bolt diameter is simply 1/4″.
