The question of which direction to unscrew a bolt and a nut seems elementary — until you find yourself holding a wrench and the part does not move. This happens at home, in the garage, when changing a wheel, or during minor repairs. Some people apply force, some hesitate, and some are afraid of stripping the threads. Below is a clear, understandable explanation with examples that will help you avoid confusion and act correctly.

Which Direction to Unscrew a Nut — The Basic Rule
A nut should be unscrewed counterclockwise. This is the standard for what is called a right-hand thread, which is used in approximately 90–95 percent of all fasteners. If you look at the nut from the front, unscrewing occurs to the left. Tightening is to the right. This is exactly the rule that should be kept in mind as the basic one.
Which Direction to Unscrew a Bolt and Is There a Difference
If a bolt has a standard right-hand thread, it is unscrewed counterclockwise. There is no difference between a bolt and a nut in terms of direction. Confusion usually arises because of an uncomfortable position, poor visibility, or excessive tightening.
Clockwise or Counterclockwise: How Not to Mix It Up
Do you not know how to unscrew a nut—clockwise or counterclockwise? To avoid making a mistake, use a simple rule:
- tightening — clockwise;
- unscrewing — counterclockwise.
Imagine a clock face. If the wrench moves in the direction from 12 to 9, you are unscrewing. If it moves from 12 to 3, you are tightening. This works in most household situations.
Right-Hand and Left-Hand Threads — When Everything Is the Opposite
There are right-hand and left-hand bolt threads. Right-hand thread is the standard one that we discussed above. Left-hand thread is rare, but it is exactly what creates the feeling that you are turning in the wrong direction.
A left-hand thread is unscrewed clockwise. It is used where the rotation of a mechanism could cause a standard fastener to loosen on its own. For example, in certain machine parts, fans, or specialized assemblies.
How to Determine Which Direction to Unscrew If the Thread Is Not Visible
Here are several hints:
- check whether there is an “L” marking (left-hand thread);
- recall whether this is a unit that rotates during operation;
- try a light movement in the standard direction without applying force.
If the bolt does not move at all, you should not immediately apply more pressure — it may be a left-hand thread.
Which Direction Wheel Bolts Are Unscrewed
For most passenger vehicles, a standard right-hand thread is used. This means that the bolts are unscrewed counterclockwise. Confusion often arises because of body position and the wrench lever. When you push with your foot or from below upward, it may seem that the direction is incorrect. However, the rule remains the same.
Why a Bolt Does Not Unscrew and What to Do
There are several reasons why a bolt does not unscrew:
- rust or dirt;
- excessive tightening;
- damaged threads;
- incorrect tool.
In such cases, you should not sharply increase the applied force — this can lead to rounded edges or a broken bolt.
How to Unscrew a Rusted or “Seized” Bolt
Effective methods that help unscrew a rusted bolt include:
- using a penetrating fluid;
- allowing time for the product to take effect;
- light taps on the bolt head;
- using a longer lever.
What should not be done is jerking suddenly or using an unsuitable wrench.
How to Unscrew a Bolt Correctly Without Stripping the Threads
To unscrew a bolt correctly, hold the wrench straight, without misalignment. Apply force smoothly. If possible, first slightly move the bolt in the tightening direction and only then unscrew it — this often helps.
How to Easily Remember Which Direction to Unscrew
The simplest formula to remember is: “Right to tighten, left to loosen.” In most situations, this is sufficient.
And if the part does not move, stop and check whether you are dealing with a left-hand thread.
So, the answer to the question of which direction to unscrew a bolt and a nut is the same in most cases—counterclockwise. Exceptions are rare and are related to left-hand threads. Knowing this simple rule, understanding the reasons why a fastener does not loosen, and using proper technique will help avoid mistakes and unnecessary effort at home, in a vehicle, or at work.
