Checking in assembly

Sorry I`m sure this has been covered before, but how do youcheck in an assembly that has external parts associated ??

For example screws from toolbox ? See in the attached image, I havean assembly with screws in it, there is an error checking that I`mnot sure how to resolve...

I normally just delete the parts
