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.

| Threads per Inch | Pitch (inches) | Pitch (mm) |
|---|---|---|
| 9 | 0.1111 | 2.822 |
| 8 | 0.1250 | 3.175 |
| 7 | 0.1429 | 3.629 |
| 6 | 0.1667 | 4.233 |
Consequently, what size is a number 8 screw?
A #8 screw size is . 164 fraction of an inch.

Hereof, is a #8 or #10 screw bigger?
Screws with a diameter smaller than 1/4" have a nominal size indicated by a number (e.g. #8 or #10). 1/4" and larger diameters are shown as inches. So, a 1/4-20 screw has a 1/4" diameter (. 250") with 20 threads per inch.
What do the numbers - such as 8-32 mean on a machine screw? The first number is the diameter. The bigger the number the bigger the screw. The second number is the number of threads per inch.
