Fasteners workbench based on screw-maker

Added
Fasteners_Flip
Fasteners_Move
Anyone want to check?

Looks correct to me. Thanks!

The Properties section of each page I think is wrong.

I have FreeCAD V0.19 installed. I used "Fastener WB" to make a counter sunk hole in my FreeCAD design. But when I click on the Diameter to change it to M4, The FreeCAD hangs.

Fastener WB was working fine on FreeCAD V0.18.

Can anyone else reproduce this ?


Edit: I merged this from a separate post

Why not just use the PartDesign Hole feature?

Here is a M4 course threaded and thread modeled countersunk hole feature in a Pad, just as a simple demo.

Here it works with FASTENERSWB_VERSION = 'V0.3.32'

not really since the hole is now not part of the Body.

Here is the file, I toggled "Model Thread" property to "false" to make the file small enough to upload here. Just toggle it to "true" if you want to 3d print the thread or similar.

Here is the same file as above but with the Model thread property toggled to true.

Thanks for the quick reply.
Here is more information about what happened and what I did to overcome it.
Fastener WB had been working fine for me since I installed it about couple of weeks back, on FreeCAD 0.18.4
I removed FreeCAD 0.18.4, and installed 0.19 version

I was trying to do a Counter sunk Chamfer on a hole:

1. I tried to select the edge and then click on Counter Sunk Chamfer button. Its own parameter setting window will appear. But selected edge would not the ticked Counter Sunk Chamfer window. As soon as I click on the it to change any parameter, FreeCAD would hang.
2. Even if I select the part, then click on Counter Sunk Chamfer button. The screen will appear, but when I select the edge on the part, it would not be ticked in the Counter Sunk Chamfer. Then I try to click on it, the FreeCAD would hang.

I removed FreeCAD 0.19, and installed 0.18.4. Then added Fastener WB. It is working now. It means, the issue is between Fastener WB and FreeCAD 0.19.

Excellent workbench, but it has two limitations as far as my needs

1)
The smallest metric thread is M1.6
I need fasteners smaller than that, for example:
https://ghw-modellbau.de/index.php?cPat ... anguage=de
or even smaller:
https://ghw-modellbau.de/index.php?cPath=4_5_7_103

2)
I need "threaded rod for tapping holes" and "threaded tube for cutting external threads" in a range of ME threads:
https://www.gewinde-normen.de/en/me-thread.html


I had a go (as discussed in this thread: https://forum.freecadweb.org/viewtopic. ... 6&start=20)
and was able to add smaller metric threads, but I stumbled beyond that both on understanding the threads databases and how to add what I wanted.

I tried to seek help by raising an issue on Github:
https://github.com/shaise/FreeCAD_FastenersWB/issues/88

I am more than happy to do all the work with adding of the data, but need help to get going.
Is there anybody out there who can help, please?

This is a great add on. Very impressive. Thanks for all the work.

The imperial bolts have an issue with 1/4 type = ASMEB18.2.1.6 UNC Machine Screws. The other sizes seem to work correctly.

It isn't an issue with the workbench as such, the specific screws work with thread = true using OCC 7.3.0 but don't using OCC 7.5.0
