Here is the tutorial.

1. Step 1:

   Start SolidWorks in Part mode.
   

   

2. Step 2:

   Top plane>>Sketch.
   

   

3. Step 3:

   Draw a circle of 10mm dia.
   

   

4. Step 4:

   Extrude it by 25mm.
   

   

5. Step 5:

   Front Plane>>Sketch and then draw this profile.
   

   

6. Step 6:

   Trim down the half of the arc.
   

   

7. Step 7:

   Revolve it.
   

   

8. Step 8:

   Reference geometry>>plane.
   

   

9. Step 9:

   Under the revolve sketch select the point and then top plane.
   

   

10. Step 10:

    Plane1>>sketch.
    

    

11. Step 11:

    Draw a rectangle of 2mm width.
    

    

12. Step 12:

    Extrude cut at 4mm.
    

    

13. Step 13:

    Chamfer.
    

    

14. Step 14:

    Bottom edge at 2mm and 45º.
    

    

15. Step 15:

    Bottom face>>Sketch.
    

    

16. Step 16:

    Convert the outer edge.
    

    

17. Step 17:

    Helix and spiral.
    

    

18. Step 18:

    Pitch=2mm and Revolutions=10.5 at start angle=0º.
    

    

19. Step 19:

    Right plane>>sketch.
    

    

20. Step 20:

    Use polygon tool and make this profile.
    

    

21. Step 21:

    Sweep cut.
    

    

22. Step 22:

    Select the triangle as the sketch and the helix as the path.
    

    

23. Step 23:

    We have the screw.
