Or you could use the square-hole racks and cage nuts, which is my preference. That way you can use any of the "rapid-rails" that the equipment might have come with, and if you strip the threads, you just throw away the cage nut, and install another. Every once-in-a-while I have to install something in a direct-threaded rack, and I'm always really annoyed.
