What do screw size numbers mean?
The first number is the diameter . The bigger the number the bigger the screw. The second number is the number of threads per inch.
What do screw dimensions mean?

How do you determine the size of a wood screw?
The size of a wood screw is generally determined by its gauge (or thickness/diameter) and the length of its shaft . Both length and diameter may be measured in inches, but the gauge is a screw size number, which can be confusing if you haven’t encountered it before.
