Everyone knows the feeling: you’re faced with a stuck object and ask yourself: Which way to loosen the screw? Right or left? Often enough, this simple question leads to confusion and sometimes even damage. In this guide, we dive deep into the world of screws and clarify the most common questions.
The Right-Left Turn: An Ancient Riddle?
For generations, people working with screws have passed down the question of the correct turning direction. In fact, there’s a simple rule: “Right is tight, left is loose.” But as with any rule, there are exceptions here too.
Left-Hand Threads: The Special Case
In some cases, for example, with certain bicycle parts or gas lines, we find a so-called left-hand thread. Here, you turn the screw to the right to loosen it. Why these exceptions? Often, the left-hand thread serves as a safety measure, preventing self-loosening due to vibrations.
How do I recognize a left-hand thread?
The good news is: A left-hand thread is marked. You usually find a notch or an arrow on the screw head indicating the turning direction.

Changing Direction: When is it Necessary?
Sometimes you can’t avoid changing the direction of rotation. This is the case, for example, when changing the direction of rotation on power tools. There are special switches or buttons on the device for this.
But what do you do if the screw just won’t budge? Here are a few useful tips:
- Rust Penetrant: For stuck screws, rust penetrant can work wonders. Let the rust penetrant sit for a while before trying again.
- Right Tool: Always use the right tool for the respective screw. An improperly used screwdriver can damage the screw and make loosening impossible.
- Forceful and Controlled: Apply force when loosening the screw, but don’t overdo it. Too much force can damage the screw.
