Hello all, Just finished the job in my shop. They are the square nuts. I used Liquid Wrench and let it set for a while to help unfreeze them from their rusty frozen places. As expected, all of the rubber crumbled even before taking it out of the piano and the rest while removing them from the stickers. I managed to get all of the nuts off OK using the regulating tool for these things on a drill clamping the sticker wires with a vice grip to hold them firmly in place. ZIIIIP off they came. Put the new ones one the same way. Fortunately, I had no problems with the new nuts fitting properly. I've replaced a boat load of these over the years and so far, knock on wood, have not encounted any screwy sizes as mentioned in another post. I also used some Protek MLP on the threads to assist the new ones so they wouldn't bind while being turned on. The most difficult part of this whole job was removing all of the rust. I wound up using my dremmel with a wire brush on the prongs in the keys. Then, I put the round brass thing that we use to clean the barrel of a gun in my drill and gently cleaned out the inside of the U in the prongs. Then, I used 4-0 steel wool on the threads on the stickers going around them. The fingers get sore after a while though! Boy, everything is cheap today too. 5 out of the set of brand new grommets had the nuts half way out or sideways in them. Luckily, they send extra's. Thanks for the advice. You might say, this job is NUTS!
