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. Metric threads are used outside of the USA, and commonly in products by HP and other global entities.
How do you determine screw size?
When looking into and determining screw size, there are two things you need to understand – the length and the thread count. The latter is also commonly referred to as threads per inch (TPI) or thread pitch. We use the TPI to determine the thread’s fineness. The number will also tell if a screw can thread through a bolt.
How do I identify screw size?
Identifying sizes can be tricky if you don’t know how to read them. They are represented in an alphanumeric code, which is difficult to understand if you are not familiar with it.

What do the numbers mean on screw sizes?
If you often do DIY, one of the popular items you are using is screws. It comes in several sizes, which you can find in the packaging. Finding the correct size can be a daunting task if you don’t know the imperial or metric system. A conversion table would be handy if you often convert between these two systems.
Metric System
The metric system was based on the meter, a system of measurement whose origin was in France in the 1970s. When taking the length of a screw, we use meters.
Standard System
The standard system, otherwise known as the imperial system, was introduced in the British Weights and Measures Act 1824. It evolved through a series of amendments in the said act. For some time, the imperial system had been the standard measurement system. However, by the late 20th century, several countries have adopted the metric system.

What is a Wood Screw?
The wood screw consists of a head that normally fits a specific type of screwdriver such as flathead, Philips, or other types.
