A FreeCAD Workbench to Add/Attach various Fasteners to Parts
Note: This workbench acts as a wrapper to the screw_maker macro created by @ulrich1a
Note: Starting from FreeCAD v0.17.9940 an Addons Manager has been built-in to FreeCAD.
You can use said Addon Manager to seamlessly install Fasteners Workbench.
For versions prior to v0.17.9940 FreeCAD requires manual installation, learn how via http://theseger.com/projects/2015/06/fasteners-workbench-for-freecad/
https://www.freecadweb.org/wiki/Fasteners_Workbench
Expand this section for a synopsis on how to use this workbench
Note: this info is also available on http://theseger.com/projects/2015/06/fasteners-workbench-for-freecad/
Usage is pretty straightforward:
- Install the workbench and restart FreeCAD
- Open a new document in FreeCAD
- Select the Fasteners workbench from the workbench drop-down list
Result: A series of screws will show on the toolbar:
-
Clicking on any of the screws will create this screw in the origin position with default size.
-
To change size/length: select the newly created screw, then go to the data tab in the property panel, there you can change diameter and length. (For now it is in metric standard):
- Changing the “thread” property to “true” will render the screw threads as well.
Please note:- generating threads takes considerable amount of time, during which, FreeCAD will not be responsive.
- the invert and offset properties are only applicable to attached fasteners.
Fasteners can also be attached to features in other parts.
- To attach a screw to a part, the part must have features with circular edges, such as holes.
-
To attach screws to holes, select the desired circular edge or several edges (You can also select a face if you want to select all holes in that face):
-
Now click on the desired screw.
Result: A screw will be placed on each of the selected features, trying to match the screw size to the hole size:
-
You can now, like before, change diameter and length from the properties panel.
-
If you wish the screw to hover above the hole, you can set the “offset” property to the desired distance.
Note: Sometimes the screw does not detect the direction correctly and appears upside down.
To correct this change the “invert” property to true OR select the screw and press the Flip button:
in the toolbar.
-
To attach an existing fastener to a different feature, select the screw, then ctrl-select the new feature:
-
Now press the Move button
in the toolbar -
Result: The screw will move to the new location:
- Note: An attached screw will move with the part it is attached to.
If you wish to detach the screw from the parent part:- simply select only the screw
- then press the move button.
*Result: the screw is now detached and can be moved individually.
- Note: An attached screw will move with the part it is attached to.
Important Note: If you wish to share FCStd files that contains fasteners (or parts from other custom parametric workbenches) with other people, they must install these workbenches as well, or else they will get errors when trying to use them.
However, if you just want to share the resulting parts, with no need to change object’s parameters, you can use the Simplify function 
to convert the fasteners to simple shapes.
Result: They will appear as new Shape parts in the model tree. You can then delete the original fasteners and save as a simple FCStd that can be read and used on any FreeCAD installation.
You can create screws with a script using the createFastener command:
createFastener(type, diam, len, threadType, shapeOnly = False)threadType can be 'simple' or 'real
shapeOnly can be True if you just want to get the object or False (default) if you want it to be added to the treeView and shown.
