I tuned for a new customer yesterday, an old straight-strung upright, circa 1920, pretty standard cheap quality English upright.  I took the action out, and noticed that the flange screws had odd heads.  I pride myself on having every kind of screwdriver - flat, Philips, Torx, Hex, Pozidrive, Security Torx etc.  These screws, however, had heads with SQUARE holes.  Looked like Hex heads at first, but square.  A new one on me! Best regards, David. P.S. I got one out using just an ordinary flat screwdriver placed diagonally in the hole.</blockquote> McFeely's (the Square Drive Screw people) has screw drivers for these. And all types of screws. 800-443-7937 <a href="http://www.mcfeelys.com/" eudora="autourl">www.mcfeelys.com</a> Their HB series of "ball" shaped square tips allows the driver to be at an angle to the screw head, perfect for getting into actions and around strings for sound board repair. I use square drive screws for upright s/b repair. I order the self-tapping ones with "nibs", these are small ridges under the screw head which help to countersink the head. I drill a pilot hole in the board and let the screw do its thing in the rib.
