Firebird/banjo Cream Plastic Keystone Button W/screw And Washer (Set of 6) Kluson reissue keystone buttons used on current Firebird, banjo, and bass tuners. Set of 6 comes complete with screws and washers. Please note that these buttons and screws DO NOT FIT Kluson original production banjo / Firebird tuners. We have increased the screw size and changed the button shaft dimensions as an improvement on the original design of the tuning machine.
