How to design a M10 Hex Nut using Autodesk Inventor 2020

In this tutorial i will be showing how to create a M10 Hex Nut using Autodesk Inventor 2020.Normally people create a polygon followed by extruding it and later creating a hole of 10 mm to design one, but that is not enough.We need to do the following steps of creating a polygon, extruding it, create a taper of 45 degree on the top and bottom surface followed by creating a hole and later threading it.
Another issue noticed in Autodesk Inventor 2020 is that the thread created on the surface is not the real thread and is just a texture map.Hence we will show you on how to create an actual thread.

2. Step 2: FIRST STEP IS TO CREATE A HEXAGON N USING THE POLYGON OPTION

So the first step is to create a polygon of six sides [basically a HEXAGON] and the hexagon should be drawn in such a way that the distance between THE PARALLEL EDGES OF HEXAGON is 17 millimeters.

3. Step 3: EXTRUDE THE HEXAGON SKETCH TO 6.6 MILLIMETERS

The next step is to extrude the hexagon we have created to 6.6 millimeters as shown.

4. Step 4: CREATE A CIRCLE ON THE TOP SURFACE OF THE DESIGN WE HAVE CREATED

The next step is to create a circle of diametre 17 millimeters on the top surface of the design .In other words, the circle should be drawn in such a way that it is tangent to the edge of the hexagon.

5. Step 5: CREATE A TAPER OF 45 DEGREE ON THE TOP SURFACE OF THE DESIGN USING THE CIRCLE SKETCH

The next step is to create a taper of 45 degree on the top surface of the design.To do this, go to the extrude option.Select the intersect option in the extrusion type and set the taper degree to 45 degree as shown in the pics.

FIG1:SET THE OUTPUT OPTION TO INTERSECT IN THE EXTRUSION PROPERTIES

FIG2:SET THE TAPER DEGREE IN ADVANCED PROPERTIES TO 45 DEGREE.

6. Step 6: REPEAT THE SAME OPTIONS ON THE BOTTOM SIDE OF THE DESIGN

PERFORM THE STEPS 4 AND 5 ON THE BOTTOM SURFACE OF THE DESIGN TO CREATE A 45 DEGREE TAPER ON THE BOTTOM.

7. Step 7: CREATE A POINT ON THE TOP SURFACE OF THE DESIGN TO CREATE A HOLE

The next step is to create a hole on the design to create a thread.To perform this task we need to create a point on the top surface the design as shown.This can be done easily just by clicking on the top surface and then press "start 2D Sketch". Then the point appears.Then click on the "finish 2D sketch".

8. Step 8: GO TO THE HOLE OPTION AND SELECT THE POINT WE HAVE CREATED ON THE TOP SURFACE.

In this step, we click on the hole option to create a hole .To create a hole, go to the hole option and then select the point we have created.

Once the point is selected, the hole appears .The diametre of the hole can be set along with the type of hole we can create. In this case, it is a simple hole of dia 10 mm.

Press ok after setting the desired parametres as shown in the above image.The hole is created.

9. Step 9: Create a thread using the THREAD OPTION in INVENTOR [THIS OPTION DOES NOT CREATE AN ACTUAL THREAD.ONLY A UV MAP IS CREATED ON THE SURFACE ]

So once the hole is created , we need to create a thread on the inner surface on the design.Select the thread option and click on the inner surface of the design to create a thread.

The thread map appears on the inner side of the design as shown in the image.

Set the size and designation type as shown and then press ok.

10. Step 10: TO CREATE AN ACTUAL THREAD USING THE THREAD MODELLER PLUGIN

So the final step is to create the actual thread unlike the thread map created by the thread option from inventor, we are going to use a plugin called the thread modeller.The thread modeller plugin helps in creating the actual thread .

Here is the link to download the plugin for Autodesk Inventor 2020.

To create a thread , we go to the thread modeller plugin .Select the option and click on the thread map we have created on the inner surface of the design.Select the thread created and click ok.

After pressing ok, an actual thread is formed.The speciality of the plugin is that it creates an actual thread on it's own using the coil and revolution options of the inventor.
