The defined diameter of metric bolts is actually slightly larger than the actual diameter of the bolt shaft. So an M8 bolt would have a shaft diameter that’s slightly under 8mm which means that the bolt should fit through an 8mm hole.
How do I know if I have M8 or 5 16?
8 is the bolt diameter, in millimetres. It usually comes with an additional number, such as 1.0, which is the pitch (distance between threads) in mm. This is the main difference with 5/16 bolt.
Are all M8 bolts the same?
M8 can be either a nut or a bolt. A standard 8 millimeter diameter bolt will have a thread pitch of 1.25 millimeters per revolution and be designated: M8-1.25. It’s companion nut will also have the same designation, therefore, it must be specified as an M8-1.25 bolt or M8–1.25 nut.

Is an M8 bolt 8mm wide?
But, to answer your Q – an M8 bolt will fit in an 8mm hole.
What does M8-1.25 mean?
For metric fasteners, you will see a M8 x 1.25 or an M8 x 1. For thread pitch, the distance between two points is the second number meaning the higher the number the fewer threads there are. This means the M8 x 1.25 is the coarse threading and the M8 x 1 is the fine thread.

How do I know what size nut and bolt to get?
A typical rule of thumb . . . Use a bolt diameter that is 1.5 – 2.5 times (up to three times) the thickness of the thinner material you are bolting together. So, for 1/8″ material, a 1/4″ diameter is often a good bolt choice. For 1/4″ thick material, perhaps a 3/8″ or 1/2″ bolt.
