Terry,

That piano would be a Knabe?  You'll have to modify a screwdriver by grinding a recess in the center.  My favorite is a Snap-On screwdriver bit for 1/2" ratchet drive.

have fun

Mike

I'm working on a piano that has smallish nuts that snug the plate to the nose bolts. They are about 3/4-inch in diameter and have a screwdriver slot across the center. You cannot use a screwdriver though because the nosebolt extends up through the nut. Clearly, the ideal tool to tighten them would be a large version of the supply-house tool made for smaller versions of these types of nuts like you would find on the key hold-down rail (what is that thing called?). Does any such tool exist? Has anyone made such a tool? What do others use to drive these nuts?

As always, they have been partially mangled by others using poorly improvised tools. I will be refinishing them and the plate and wish to do things properly. Any ideas? Thanks.
