Hello
I have some trouble to recreate this piece : 
but I have already did this : 
but with the threading fonction I have the standard threads and I can't edit the standard threads
Do you think I should use another fonction ?
Hello

Do you think I should use another fonction ?
Where do you get this 'Flex'?
Edit: Never mind...
Insert > Feature > Flex
Menu Insert - Features - Flex - Twisting
Check that part with the mating part in Motion Analysis for interference.
Thank you for your answers, I have didn't think to make it like this.
I have found another way, because after make this first piece I had another part to modelize, the base : 
and to create this I used the helix/hairspring function to make the trajectory and then I made a sketch( the profile). Last , I used the sweep material removal function to select the trajectory and the sketch .
Base? Its no problem:
1. Make base shape
2. Insert first part
3. Set position
4. Use feature "Indent" with cut option. You can set clearance.
5. Delete or hide first body
Easy, fast, nice...
Use "Flex" command.
For top hole (if you have a problem) you can use Hole Wizard (or Cut Extrude and add "Cosmetic Thread"
