The simple Nut model with inner threads is created by following the below YouTube tutorial,
A couple of different representations of the nut are explained in this video (about 45 min)
Explains some of technical glitches with FreeCAD and also explains methods to overcome.

Using Part Design Workbench, create a Sketch as shown below in XZ plane.
Revolve the sketch about the Vertical axis (Z).
Create a sketch on the top flat surface selected below.
Create a Hexagon with center as the origin and 2 vertex in Y-axis, symmetric to X-axis.
Set the distance between 2 vertical sides as 10 mm.
Draw a circle with center as orign and set radius = 7 mm.
Set the distance between 2 vertical sides as 10 mm.
Draw a circle with center as orign and set radius = 7 mm.
Create a Pocket with the new sketch selected
This completes the nut model with no inner threads
Using Part Design Workbench, create a Sketch as shown below in XY plane (Top View)
Pad the Sketch with Length = 4.7 mm.
Create another sketch by creating a new body.
Revolve the Sketch about the Vertical axis.
Select the Part Workbench
Selected the Padded Hexagonal object and multi-select (Ctrl + Click) on the Revolution shape
Selected the Padded Hexagonal object and multi-select (Ctrl + Click) on the Revolution shape
Click the boolean operation of intersection
This completes the nut model with rings to visually represent some groves like threads.
Using Part Workbench, create a Helix with parameters as shown below
Using Part Design Workbench, create a body and create a sketch and draw a triangle as shown below.
Using Part Workbench, select sketch and apply Sweep function.
Select Sketch and Move that to the Profile window.
Select Path and click on the Helix shape. Multi-select and click on all the helix segments.
Select Solid and Frenet options and click Done.
Select Sketch and Move that to the Profile window.
Select Path and click on the Helix shape. Multi-select and click on all the helix segments.
Select Solid and Frenet options and click Done.
Click Ok. The model space will show the triangular helix as below
Using Part Design Workbench, create another body and create a sketch and draw as shown below in XZ plane.
Revolve the Sketch about the vertical axis
Select the top face and draw a sketch as below
Apply Pocket and select Through All
Select the nut shape and then multi-select the Sweep shape and apply Boolean Cut
This completes the nut model with helical inner threads.
