Tapped Hole
A tapped hole has threads cut into the inside surface. Threaded components like screws or bolts can be fastened to the threading.
In the model, the full geometry of the threading is not created in the hole. Instead, a quilt that represents the larger outer diameter of the screw or bolt is created.
This example shows the lower part of two parts being joined. A tapped hole is made in the lower part so an M5 bolt can be fastened to the threading of the lower part after passing through the upper part. You can see the upper part in the related topic Clearance Hole.
