A blind nut mountable in mounted members such as panels of a wide range of thicknesses. The blind nut includes an internal threading portion, a hollow tube-shaped portion adjacent to the threading portion, and an open flange formed in the tube-shaped portion on the end opposite the internal threading. The internal threading portion and the tube-shaped portion are inserted into a mounting hole in a mounted member, and a section of the tube-shaped portion is plastically deformed to enlarge the diameter in order to grip the mounted member between the deformed enlarged-diameter portion and the flange, and mount the blind nut in the mounted member. The tube-shaped portion has a tapered portion adjacent to the internal threading portion, and a cylindrical straight portion adjacent to the flange. The tapered portion and the straight portion are plastically deformed to widen their diameter and mount the blind nut on the mounted member. |

1. A blind nut including an internal threading portion having internal threading formed on the inside, a hollow tube-shaped portion adjacent to the threading portion, and an open flange formed in the tube-shaped portion on the end opposite the internal threading, the internal threading portion and the tube-shaped portion being inserted into a mounting hole in a mounted member, and a section of the tube-shaped portion being plastically deformed to enlarge the diameter, thereby gripping the mounted member between the deformed enlarged-diameter portion and the flange, and mounting the blind nut in the mounted member,
wherein the tube-shaped portion has a cylindrical straight portion adjacent to the flange, and a tapered portion becoming gradually narrower from the straight portion towards the internal threading portion.
