Dean, I believe I have seen these in basement walls and at hardware stores. Does it use a machine screw? Maybe this would be the simplest and most elegant solution. I had been thinking how much nicer the design would be with a screw threading into a metal nut of sorts, rather than into wood. Thanks! I have replaced popped wood screws with T-Nuts to hold down a damper pedal bracket on the bottom board of a Kawai studio. Seems like quite an improvement.
