To provide a tightening confirmation display method capable of dispensing with a tightening confirmation process and managing the tightening torque by simply visually confirming the sure execution of tightening in fastening, and a confirmation display jig for implementing the method.

When the fastening part to which paint to be scraped adheres is tightened above designated torque by a fastener 30, a scraping blade 22 provided on the fastener scrapes the paint of the fastening part to display tightening confirmation. A clutch mechanism may be provided for transmitting the turning force for rotating the fastening part to be tightened to a surface to be rotated of the fastening part when it is below the designated torque, and intercepting the transmission and allowing the scraping blade 22 to which the turning force is transmitted to abut on the paint of the fastening part it is above the designated torque.
