## What does gauge mean in screws?

The gauge of a screw is defined by the thickness (diameter) of the un-threaded part of the screw known as the shank. Ordinarily, in the United Kingdom the head size is roughly twice the diameter of the shank, although there are some exceptions associated with hybrid, hardened, DIN Standard (metric) and imported screws.

1. A gauge number for screws in the imperial system corresponds to a certain fraction of an inch in diameter. …
2. For example, a #0 gauge screw is 1/16 of an inch in diameter, #1 is 5/64 of an inch, a #2 is 3/32 of an inch, and so on.

## How do I know what size my screw is?

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.

## How do you pick a screw size?

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.
