Bob, Frank, et al, I've not seen square headed rim bolts used on a Steinway plate, but I've come across several in which they've been replaced. I've done it myself. Some of those old bolts were pretty soft. If I come across a piano that has even one rim bolt broken (or a bolt that looks like it might be about to break) I'll replace the whole set. -- ddf ------------------------------ Frank Weston wrote: > I've never seen square rim bolts, and one would have to question why anyone > would ever need to replace hex head rim bolts with square.
