Toolbox missing 12-24 SHCS?

You'll have to excuse me, I'm trying to shake off the rust as I come back to Solidworks after working in Inventor for the last 3 years.

The ANSI Inch toolbox library doesn't seem to contain any #12 socket head cap screws.  Why would this be?  We keep these on hand in multiple lengths in our tool crib and I would like to be able to use them in my assemblies.  What's he easiest way to add them to the toolbox?
