But the other kind of threading.
These bed attachment holes tend to get crapped up over time with dried up oil, lint, and various other kinds of dirt. Since they're a fine thread (9/64-40 of all things), this can quickly jam up any kind of attachment screws you try to fit into them, unless you chase the threads with an appropriate tap.
Thankfully, while not a common size outside of the world of sewing machines, the tap is relatively easy to find. After running it through both holes, the thumb screw can now spin all the way in with ease.
