What is the screw’s thread?
The thread is the ridge that runs around the screw’s body.
When viewed from the side, a screw’s thread looks like a series of ridges and grooves along the screw’s body. Although these ridges are all part of a single thread, they are referred to as the threads.
The pitch is the distance from one ridge to the next.
This measurement will tell you how far the screw will travel in one rotation. A screw with a greater pitch (more space between threads) will travel further in one rotation.
