How can you tell if a bolt is metric?

Metric fasteners are specified with a thread pitch instead of a thread count. The thread pitch is the distance between threads expressed in millimetres (measured along the length of the fastener). For example a thread pitch of 1.5 means that the distance between one thread and the next is 1.5mm.

How do I know what size nut to buy?

If the nut is metric, count the number of lines on the tape measure to find the measurement. If you count 9 lines, the size is a 9-mm (millimeter) nut. If the nut is US standard, count the smallest lines on the tape measure in sixteenths. Add the sixteenths together to find the size.

What does M2 screw mean?

M2 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.

What is diameter of M2 screw?

Is an M8 bolt 8mm wide?

But, to answer your Q – an M8 bolt will fit in an 8mm hole.

Is M8 same as 8mm?

M8 is not exactly 8mm but it is sufficient from a non-engineering point of view as long as the thread pitch is correct. Luckily, most commonly available metric bolts have the same pitch. Regarding tolerance for common uses it can also often be ignored.

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 you measure metric threads?

Metric thread sizes are specified by diameter and pitch, which is the space between threads. For the size M6 × 1 mm, the pitch is coarse, while the size M6 × 0.75 mm has a fine pitch. If you don’t know the pitch, choose coarse threads, they’re the industry standard.

Can you use standard sockets on metric bolts?

Yes, you can use some sockets on both metric and SAE sizes. However, you need to be careful, as most times they are not exactly the same, and you can strip a bolt by using an SAE socket on a metric bolt and vice versa.

How do I know what size nut I need for a bolt?

To measure the diameter of screws and bolts, you measure the distance from the outer thread on one side to the outer thread on the other side. This is called the major diameter and will usually be the proper size of the bolt.
