Screws make work easier by converting rotational motion into linear motion, allowing for the application of force over a longer distance with less effort. This helps to increase mechanical advantage, making it easier to drive screws into materials or hold objects together securely. Additionally, screws can provide a mechanical advantage by increasing the force applied and enabling finer control over the tightening process.
Screws have a helix design, that drills into the wood, and also holds materials together.
