Solidworks usually give us the standard sizes of thread through toolbox. And from smart fastener command we can easily create screws, nuts and washers we need. Screws from toolbox are configured in different standard sizes defends of what we choose during creation.

But do solidworks will give us the screw with correct flute? Or a well detailed screw? Of course not! Because the program need to save memory, simply means creating additional feature means additional memory to be consumed. And this really affects the speed of the program.

It is a fact that in cad designing we do not need a well detailed screw to have a good design. But as wealways say – there is always an exemption.  Sometimes we need to show thread flute for presentation or maybe there is a need for us to show it due to some reasons. This article is just a little tutorial on how to
create a thread flute on a screw we got from solidworks toolbox.

Figure 1 shows a standard socket head cup screw (M5x0.8mm) from toolbox.

Figure: 1


Before proceeding, here are the things we need to know before we can create an exact screw threadflute: (1) Type of thread (2) Major diameter (3) Pitch (4) Root depth



Below is the procedure in creating a thread flute:

1. Create a reference plane. Plane distance should be the equal to thread pitch.



2 . Sketch a profile based on the prefer thread type.


3. Make a cut for thread root diameter


4. Create a helix. Helix pitch should be the same on thread pitch.



5. Make a sweep using the previously created thread profile and the helix as a guide curve.



6. Cut to make a chamfer on screw end



After the 6 steps are done you can now see the thread flute on screw from solidworks toolbox .
