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 is M in nut bolt?
The letter ‘M’ indicates that this bolt uses a metric thread. The number ‘8’ refers to the nominal diameter of the bolt shaft in millimeters. The number 1.0 is the thread pitch of the bolt, which is the distance between threads, in millimeters. And the final figure, 20, is the length in millimeters.
How can you tell if a bolt is metric or standard?
Telling the difference between a metric and imperial bolt is easy. If the bolt has lines on the head its standard or imperial. If the bolt has numbers on the head then its metric.
