## What is standard metric thread?

M6 threads are 6mm metric screws. The standard metric rack screw is called M6 x 1. The ‘M’ means it’s metric. The ‘6’ is the outside diameter measured in millimeters, and the ‘1’ is the distance between adjacent threads, also in millimeters.

How are metric thread sizes measured?

Imperial measurement fasteners are classified by threads per inch, so a 1/4-20 bolt has 20 threads per inch (TPI), while a 10-24 screw has 24 threads per inch. You can determine the threads per inch of a metric fastener by multiplying the millimeters by 0.03937, and then dividing 1 by that number.

### What pitch is metric coarse thread?

1.5mm
Understanding Inch & Metric Thread Callouts 5 (coarse) thread has a 1.5mm pitch, while an M10x1. 25 (fine) thread has a 1.25mm pitch. To simplify metric thread callouts, the international (ISO) standard for metric threads eliminates the pitch callout on coarse threads.

### What size are rack mount screws?

The three most common sizes of rack screws found in rack mounted equipment are: 10-32 – The “10” refers to the size of the screw and the “32” denotes 32 threads per inch. It is a very common screw type and is available in different driver styles ( Torx and Philips are the most common).

What is bolt pitch?

In fact, the bolt diameter is a little smaller and the nut diameter a little larger. But it is easier to specify the components by a single size designation since the bolt and nut are mating components.) Pitch is the distance from the crest of one thread to the next or the distance from one thread groove to the next, measured from crest to crest.
