Tutorial - Modeling Bolt with terminating thread in Creo Elements aka Pro/E?

1. Step 1

   Sketch >> Top plane.
   
   

2. Step 2

   Draw a circle of 20mm dia.
   
   

3. Step 3

   Extrude it by 100mm.
   
   

4. Step 4

   Sketch >> Top face.
   
   

5. Step 5

   Draw a polygon with 17mm radii circle.
   
   

6. Step 6

   Extrude it by 10mm.
   
   

7. Step 7

   Sketch >> Right plane.
   
   

8. Step 8

   Take reference with the edges and draw a triangle.
   
   

9. Step 9

   Revolve it about the center axis with remove material.
   
   

10. Step 10

    Chamfer the lower edge with 45 x D (D=2.50).
    
    

11. Step 11

    Insert >> Helical Sweep >> Cut.
    
    

12. Step 12

    Click Done.
    
    

13. Step 13

    Select Front plane.
    
    

14. Step 14

    Click Default.
    
    

15. Step 15

    Now draw a center line about the vertical axis.
    
    

16. Step 16

    Draw another line and spline tangent to it.
    
    

17. Step 17

    Exit the sketch. Now input the pitch value = 2.50.
    
    

18. Step 18

    Click OK and now draw the section. Draw a Iso triangle with 2.4mm at 3mm from axis.
    
    

19. Step 19

    Exit the sketch and define the cut-side be inside of sketch.
    
    

20. Step 20

    Click OK and the feature is generated. We can see the thread ended in regular fashion.
    
    

21. Step 21

    We have the bolt created.
