The length, depth and angle of a screw's thread often depends on the materials in which it's meant to be used. For example, machine screw threads are finer and partnered with a nut or tapped hole, while wood screws have a deeper thread. Sheet metal screws also have coarse threads like wood screws but tend to be shorter.
