Tutorial - Making a bolt in Solidworks?

Here is the Tutorial. The attached file is the final output.

  1. Step 1:

    Start Solidworks.

  2. Step 2:

    Right Plane>>Sketch.

  3. Step 3:

    Make a polygon circumscribed with circle dia 18mm.

  4. Step 4:

    Extrude it by 7mm.

  5. Step 5:

    We have the extruded polygon.

  6. Step 6:

    On the right plane of the polygon start a sketch. Normal View to sketch.

  7. Step 7:

    Make a circle tangent to the sides of polygon.

  8. Step 8:

    Under features tab select Extruded Cut.

  9. Step 9:

    Change extrude depth to 7mm. The draft angle to 60degree and check the flip side to cut. Click OK.

  10. Step 10:

    Now you can see the polgon has rounded edges.

  11. Step 11:

    Repeat the same steps for the other face also.

  12. Step 12:

    Click on the right side circular face of the polygon and select sketch.

  13. Step 13:

    Make a concentric circle of dia 16.6mm.

  14. Step 14:

    Extrude it by 0.60mm.

  15. Step 15:

    Select the circular face of the extruded body in previous step and select sketch.

  16. Step 16:

    Make a circle of 12mm dia concentric to previous one.

  17. Step 17:

    Extrude it by 50mm.

  18. Step 18:

    Now we have the basic body of the bolt.

  19. Step 19:

    Under features>>fillet arrow>>Chamfer.

  20. Step 20:

    Select the circular edge of the bolt.

  21. Step 21:

    Change chamfer settings to 1mm distance and 45degree.

  22. Step 22:

    Now we have the chamfered body.

  23. Step 23:

    Select this face and sketch.

  24. Step 24:

    Under Sketch Tab choose convert entities.

  25. Step 25:

    Select this edge and then click OK.

  26. Step 26:

    Again click OK to exit convert entities.

  27. Step 27:

    Under Features tab>>Curves>>Helix and Spiral.

  28. Step 28:

    Choose Defined by Height and Pitch. Change the Height Value to 46mm and pitch value to 1.75mm keep other settings default.

  29. Step 29:

    Click OK and we can see that helix has been creted.

  30. Step 30:

    Top Plane>>Sketch.

  31. Step 31:

    Make a equilateral triangle of side 1.7mm with one point coincident to the edge of the bolt.

  32. Step 32:

    Under Features tab choose Swept cut.

  33. Step 33:

    Choose the triangle sketch as profile.

  34. Step 34:

    Choose helix as the path of the swept cut. Click OK.

  35. Step 35:

    Now we are done, we have the bolt created.
