I can't turn my nut on my screw

3D Design Assembly
1

Good evening

Being in my final year of high school, I am a novice in this field and I have a lot of trouble with solidworks. I wanted to create a screw nut system for my project, so I created the screw and the nut beforehand (following a tutorial) but when I have to assemble them (rotate the nut around the screw) nothing works. I have many errors that appear. Would there be anyone among you who could take some time to look at what I did and possibly correct my problem directly on solidworks??

Thank you

Sam :)

Hello

If you put your assembly without the parts concerned, we won't be able to help you.

It's best to make a composition to take away from your blend.

Since we don't all have the same version of Solid as you, we may not be able to open your assembly.

Can you put a screenshot of the constraints you put between your screw and your nut?

What is the real need:
- just assemble a nut on a screw;
or
- Have realistic movement of the nut on the screw.
If you think about the degrees of freedom blocked by your constraints, you will soon have the solution.

Is there a need for 3D printing afterwards?
Just because it's nice to have a realistic thread but in terms of modeling to make plans, it won't work.

Visually speaking

There seems to be a problem between the hexagon bolt head and nut and screw diameter?

Regardless of the judicious remarks of my little comrades, ;-)  I have the impression that there is a superfluous pile of constraints.

The helical stress acts as both tangent and coaxial stress. So a single constraint, in this case the helical, must be sufficient.

Solidworks does not allow you to put contradictory constraints between them.

But we would have to have the entire model to see if there are any other errors that would make the helical stress unusable.
