Not to be contrary, but don't the non-clip screws just pass through unthreaded holes in the liner? And then screw into inserts in the spacers (and into the stop-pin on the Military)?
I'll definitely second that they're rock-solid, as well as lighter and slimmer than you'd expect (esp. with 5/32" blade stock!)
