Home » How to add cosmetic threads in SolidWorks?

Cosmetic threads are a quick and lightweight method of indicating threaded components in a design. The screw mate option cannot be used as these threads to not contain any geometry.

Internal Threads – Hole Wizard


Hole wizard is the easiest method to add an internal cosmetic thread, there are a variety of hole options to choose from. To add an internal cosmetic thread, follow the instructions below:

  1. Use a sketch containing fully defined point location(s) where the holes are to be placed, then exit the sketch. Refer to the comment in step 7.
  2. Click on the “Hole Wizard” button from the features tab.
  3. Select the option for a straight tap from the hole type selection. Set the standard and type options appropriate to the thread being used.  Use ANSI metric and bottoming tapped hole for this example.
  4. Choose the appropriate size of hole from the hole specifications section. M10x1.0 will be used.
  5. Set the desired end condition for the hole. Select blind for holes that do not pass through the entire body, otherwise use through all.
  6.  In the options section select the cosmetic thread option and tick the box to include a thread callout.
  7. Switch to the positions tab to specify the location of the hole. Select the face to place the hole on, then click anywhere on the surface a hole is required. Holes can be placed without a pre-existing sketch, however their positions will not be fully defined, edit the sketch to fully define the hole positions. Tip: to place a hole that is concentric to a curved body hover over the circular edge to display the center of the curve, place the hole on that point and it will be constrained.
