Fasteners ChamferHole

Description

The Fasteners ChamferHole command chamfers holes for countersunk screws.

Chamfered holes for countersunk screws

Usage

1. The command can detect screw diameters automatically. Holes must have the correct diameter for this to work. For example an M5 screw requires a 5mm pass hole or a 4.2mm tap hole. The Fasteners ScrewCalculator command can be used to determine tap hole diameters.
2. Select a part with circular holes.
3. There are several ways to invoke the command:
   • Press the Make countersunk button.
   • Select the Fasteners → Make countersunk option from the menu.
4. The Chamfer holes for countersunk screws task panel opens.
5. The Edges to chamfer list shows all circular edges of the selected part.
6. Select the edges you want to chamfer by doing one of the following:
   • Click individual circular edges or faces with circular edges in the 3D view:
     • There is no need to hold down the Ctrl key.
     • Each selected edge is checked in the Edges to chamfer list.
     • The screw diameter for each edge is detected automatically.
     • Edges cannot be deselected in the 3D view.
   • Select or deselect edges by checking or unchecking them in the Edges to chamfer list:
     • In this case the screw diameter is not detected automatically.
7. Optionally change the screw diameter of individual edges in the Edges to chamfer list by double-clicking their Diameter field, and selecting a new value from the dropdown list that appears.
8. Optionally change the screw diameter of all selected edges by selecting a new value from the Diameter dropdown list below the Edges to chamfer list.
9. Optionally specify a Screw type.
10. Press the OK button.
11. A Countersunk object with a chamfered recess for each selected edge is created.
12. Optionally attach screws. See Fasteners Workbench.

Notes

• Countersunk objects are parametric. An existing Countersunk object can be edited by double-clicking it in the Tree view. The Chamfer holes for countersunk screws task panel will open. Circular edges can be added or removed, and the parameters of edges can be changed.
