In the below photo is a transparent side panel, and a horizontal panel attached to it. There is a bolt passing through the side panel and into the horizontal panel.
The slot circled in red is used to retain the nut of the bolt.
The bolt is from the Toolbox, as will be the nut.
I'm not sure what to select in order to make the insert function of the Toolbox work. I've tried many combinations, and the nut always comes up at the origin of the assembly.
Can anyone give me some pointers on what I should use as selections when importing from the Toolbox?
