Tutorial - Creating hex nut in SolidWorks?

Here is the tutorial.

  1. Step 1:

    Start Solidworks in Part mode.

  2. Step 2:

    Top Plane>>Sketch and make this sketch.

  3. Step 3:

    Extrude it by 7mm.

  4. Step 4:

    Click the upper face and then sketch.

  5. Step 5:

    Choose normal to view.

  6. Step 6:

    Make a circle tangent to the side of the polygon.

  7. Step 7:

    Under features tab choose extrude cut.

  8. Step 8:

    Check flip side to cut and draft enabled at 60degrees.

  9. Step 9:

    Click OK and we have rounded edges.

  10. Step 10:

    Repeat the same step for bottom face.

  11. Step 11:

    Under fillet choose chamfer.

  12. Step 12:

    Select the circular edge on the upper face, Change the length to 1mm and angle to 45degree.

  13. Step 13:

    We have now chamfer created.

  14. Step 14:

    Repeat the same step for the lower edge.

  15. Step 15:

    Under Features tab>>Reference geometry>>Plane and select top face and enter a distance of 10mm which is default value.

  16. Step 16:

    Choose plane1 and then sketch.

  17. Step 17:

    Normal to view and then select the inner cirular edge of the cylinderical face and then convert entities.

  18. Step 18:

    Exit the sketch and under features tab choose Curves>>Helix and spiral.

  19. Step 19:

    Change the configuration to height and pitch. Enter height of 27mm and pitch value of 1.75mm and click ok to create a Helix.

  20. Step 20:

    Choose front plane and then sketch.

  21. Step 21:

    Draw a profile of Equilateral triangle of side 1.7mm (less than pitch value) having one point coincident to the edge and symmetry.

  22. Step 22:

    Exit Sketch and Select Swept cut in Features tab.

  23. Step 23:

    Select the triangular sketch as the profile and the helix as the path for swept cut.

  24. Step 24:

    Click OK and the cut is performed. Now hide the plane1.

  25. Step 25:

    The Hex nut is created.
