Term for this bolt attachment mechanism

boltshardware

We're installing Ikea cabinets in our kitchen. The wall cabinets attach to a rail using a bolt-and-bolt-attachment-thingy that slides onto the rail, and the cabinets are then fastened to the bolts. It seems pretty ingenious to me…and I'd like to duplicate the mechanism to solve a problem we're having.

What I'd like is to be able to do something very similar, but using a larger bolt, and preferably a much wider plate thing, so that I can attach the plate to the bottom of the base cabinets for threading the feet onto it (the one that came with the feet isn't long enough for our very not-level floor). So…is there a term for this? Is there a way to recreate this with off-the-shelf (or at least the internet's shelf) parts that don't require any machining?

What I think you are referring to are commonly called "T" nuts. They are made for wood, formed metal channels and other applications. A google search may produce images that you can find at a home improvement center.
