A basic Screw Thread Tutorial detail using (Sweep Helix). This example is using the few dimensions of a M4 x 0.7 6H standard screw. I keep this "3D Screw Template" in my files for anytime I need that screw (I just change the length and put the necessary head on top, or what ever). The basic steps used here can be used in any CAD software. Just a Minor Diameter and Thread Length, the "Tooth" detail with the Major Diameter, (run the Pitch, helix sweep), Then to clean up the ends, rotate a Chamfer sketch. Download my pdf files for an easy step-by-step tutorial (done in FreeCAD).
