How do I measure the length of a screw?
The length of a countersunk screw is measured with the head. For all other heads, the length is measured under the head.
However, make sure you choose the screw material according to the material being drilled:

| Diameter | 4.2 | 4.8 | 5.5 |
| Head Tickness | 4.25 | 4.45 | 5.45 |
