I have looked at the fx parameters as i want to change the Chamfer1 (fx.d5 & fx.d6) so that i can place a fillet on the nut....how do i decrease the face size so that i can use a small size fillet on the nut

Set d5 and d6 to 95% of the face width value (or whatever percentage you need).
Thank you for solution
Can both the Bolt and Nut have a real thread on the part rather then an appearance thread?
Is this possible?
Best Regards
James
I wanted to see if i could learn the technique myself but i not sure how to start this.I think a coil feature would be one of the required tool but any suggestions on how to employ the technique of creating a real thread.
Cheers
JS
See attached
or
try Fusion 360.
Bolt looks great
I am presuming the nut follows the same technique but will only require 1 coil feature
Thanks again
Yes.
If you want more precise geometry (I have sharp V at OD (and at the root, but that is less of a concern)) consult your Machinery's Handbook. Also, if you are going to 3D Print I chase a second thread offset a bit to increase clearance as the 3D Printing processes are not precise.
I thought i would post back with the 2 examples.
Is this Nut thread correct to suit the Bolt?
How do i now constrain these so that they do not interfere with each other in assembly mode?
eg....The assembly attached is constrained but there is interference?
Maybe it cannot be used this way and cosmetic threads will be better
Thanks
Note that you did not fully cut the helix.
You must send the cutting tool all the way through the part - just like the real world.
Also - the Helix in your Nut part is running CCW where it should be CW. (Check the preview helix - don't assume the icon arrows are same axis direction as your design intent.)
Remember the board drawing exercise from the last century - when you section nut the back side threads appear in opposite direction from the fastener. I always had trouble visualizing this back on the drawing board. Now you can cut it in half and see.
See why the rotation axis was flipped relative to viewer.
Thanks for the help
It now all works.
Just curious why was the dimension 1.9999mm used on the triangle / coil sketch instead of 2mm?
Thanks
JS
In reply to your comment "Just curious why was the dimension 1.9999mm used on the triangle / coil sketch instead of 2mm?"
If you use the exact 2mm thread pitch and use a 2mm coil pitch you'll get an error that the coil is self intersecting. It the same with almost, if not all, physical modeled threads.

Ha! Old habits die hard. I just remembered that Autodesk changed the sweep behavior in 2014 to be more forgiving of self-intersecting "errors". I just changed it to 2mm and rebuild-all and no error.
I need to try this in SolidWorks and Creo now as I have had to use the same fudge in the past in those programs as well.
