Zusammenfassung:	A rotary plate fastener ( 24 ) is provided for firmly fastening ceiling fan blades ( 26 ) to mounting brackets ( 20 ). A plurality of protuberant members ( 32 ) extend upwardly from the mounting brackets ( 20 ), and have respective head portions ( 72 ) and shank portions ( 74 ) which fit through apertures ( 62 ) in the ceiling fan blades ( 26 ). The rotary plate fastener ( 24 ) has an upper surface ( 36 ), a lower surface ( 38 ), and peripheral edge portions ( 42 ) extending between the upper and lower surfaces ( 36, 38 ). Openings ( 46 ) formed in the peripheral edge portions ( 42 ) are aligned for registering adjacent to the shank portions ( 74 ) of the protuberant members ( 32 ), and then the rotary plate fastener ( 24 ) is rotated to twist the openings ( 46 ) around the shank portions ( 74 ) and press the rotary plate fastener ( 24 ) between the head portions ( 72 ) of the protuberant members ( 32 ) and the upper surface of ceiling fan blade ( 26 ).
