Threaded hole in a part
Threaded hole in a part
(OP)
Hi all,
I am really novice with SolidWorks, so please bear with me.
Using SolidWorks toolbox, we can use some standard screws in our design, is there any tool in Solidworks that can assist us in making the threaded hole in a part in such a way that it corresponds to the standard screw. I have already seen the hole wizard, using it we can only make the holes without the thread or we can show a cosmtic thread but we cannot make it. In other words, I would like to know how to make the thread that corresponds to this standard screw and can be assembled with it.
Thank you for any proposed solution.

RE: Threaded hole in a part
The only time I model a helical thread is when it is molded into a part, usually a plastic or die cast part, and even then I keep it suppressed most of the time. I will unsuppress it for making images that need to display the thread or for sending the part for rapid prototyping.
DO Use the Hole Wizard for the threaded holes. I use the middle selection for the thread display (pilot hole modeled with dashed line representing major diameter). The drawings will show the proper hole callout, i.e., pilot hole size and depth and thread callout. For a custom shaft with male threads you should look into the Cosmetic Thread feature. It will give a similar appearance and callout information as the Hole Wizard.

My experience trying to print the threads is no good because of shrinkage and other factors.

If it's large, you may get away with 3D printing.
If it's small, ctopher's suggestions are good.
Whenever possible, I prefer to create a pocket for a hex nut and insert it after printing. This creates a much stronger connection.

The thread size is M7x.75 and that's why it may be difficult to hand tapping the threads (it depends on the plastic used in 3D printer, I have no idea about its properties). It is a good idea to create a pocket for a hex nut but I have to see how to ensure that the hex nut will not leave the pocket when the part turns upside down. Also, I will take the clearance and orientation-layering problems into consideration.
RE: Threaded hole in a part
With regard to retaining a hex nut, it could be a friction fit in the pocket, or even bonded in place.
Can you post an image of the part, or the part itself?

Jboggs, I have given this size according to my part dimensioning without taking into consideration the available standard threads. I thought that it would be simple if I use some standard screw if there is an automatic way to create its helical thread using SolidWorks (e.g. M8) but if there is nothing like that, I prefer to create M7 which is more appropriate for my part.

You can make the width of slot for the nut match the flats of the nut with a light press fit. Or change the direction of the nut insertion to be radial instead of axial, then press a dowel or use another method to block the radial retreat. Lots of ways to do it with 3d printing, though I find that the light press is the easiest if you have a good feel for your printer's abilities.
