What are the different sizes of screws?
Screw Sizes
For screws measured in inches, diameters of 1/4 inch and smaller (for machine and sheet metal screws) or 5/16 inch and smaller (for wood screws) are expressed with a # and a whole number (ex., a screw with a major diameter of 3/16 inch is a #10 screw). Smaller numbers indicate smaller diameters.

What is a No 6 screw?
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 does screw sizing work?
A screw for wood is sized by two distinct numbers, first is the gauge of the screw which is the diameter. This means, the larger the number the larger the diameter. Therefore, a number 12 screw is larger than a number 4 screw.
Which is bigger #6 or #8 screws?
In all cases, the larger the number, the larger the size. Consequently a #8 screw is larger than a #4 screw, just as a 3 inch bolt is larger than a 2 inch bolt.

How do you know what size screws to get?
The most important factor in screw selection is length. 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.
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. Check your state and local codes before starting any project. Follow all safety precautions.

What are thread sizes?
Thread sizes in inches are specified by diameter and threads per inch. For example, in the screw size 10-24, the first digit refers to the thread diameter, the and second digit is threads-per-inch (TPI). When the diameter smaller than 1/4”, the value is indicated by a number, like #1 or No. 1.

What is thread size of a screw?
Thread sizes are given in nominal sizes, not in the actual measurement. The exact measurement is slightly below the named or nominal size. For example, a 6mm bolt may measure 5.8mm or 5.9mm, but it is called 6mm bolt. It is also common to use “M” before the bolt size, such as M6 for a 6mm bolt.
