The reason that your toolbox parts will come in huge like that sometimes happens when you share data with other people.
Depending on how toolbox is setup.
By default toolbox keeps its parts on your hard drive and when you first install it, it has blank parts without any configurations. When you add a new fastener it opens the toolbox part on your hard drive, creates a new configuration then saves that part and inserts it into your assembly.
This works great until you send your parts and assembly to someone else.
When they open your assembly that contains toolbox parts, it will look in their directory... and if for some reason they have not used that particular size fastener it will not see that configuration in the part and it will default to the blank screw size (usually a 1" x 1" bolt).
The best thing to do in that case is if you are sharing data between users in house is to make sure that you setup toolbox parts on a shared drive on your server.
If you are sending data out to a vendor, to make sure that evrything goes with your project, create a new directory somewhere, then you open the assembly that contains your tool box parts. and saver the assembly, part files, and toolbox parts in a new folder using the refernces button in the saveas dialog box, making sure that they all get placed in that new directory.
Now you can zip them up the intire folder and send out the data.
But like I said IN HOUSE by all means use a common toolbox folder for sharing these files.
Hope that helps
