A gage number like “6” is the diameter and the length is the length of the screw that goes into the wood not inclusive of the head unless it’s a flat head. The smaller the gage number the smaller the screw diameter (opposite of nails and wire diameter).

How do I know what size screw I need?
The general rule of thumb is that the screw should enter at least half the thickness of the bottom material, e.g. 3/4″ into a 2 x 4. The other factor is the screw’s diameter, or gauge. Screws come in gauges 2 through 16. Most of the time you’ll want to go with a #8 screw.
How do you match a screw size?
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.
