I'm in the process of building my own workbench and wanted to include leveling feet to compensate for variations in the garage floor. I found this website:

http://www.levelingmounts.com/

and as you will see, their site is a bit difficult to navigate. I gave them a call, and the lady on the phone couldn't have been more pleasant to work with. I explained to her what I was looking for, and they pretty much had exactly what I needed. Since I was looking for a hex socket on the top of the shaft, I had to move up to the heavy duty levelers which are overkill with a 5,000 lb rating, but it had all of the features I wanted.

If you need leveling feet, I would highly recommend this company.

Here is a pic of the mount I got with a #5 in the background to give you an idea of scale.
