What are screw sizes?
Screw sizes are designated by a number that indicates the diameter and the length of the screw in inches (Table 10-2). The smallest diameter screw is 0, and the largest commonly available is 24. For bench work, the most useful sizes are 4 through 12. Of those sizes, 6, 8, and 10 are probably used more than any others.
