Claims

[Scope of utility model registration request]

Protrusions with an apex angle of 120 degrees are placed at six equiangular positions on the outer circumferential surface of the effective cylindrical portion, which is the base of the nut, within an included angle range of approximately 20 degrees in a plane perpendicular to the axis of the nut body. A lightweight nut characterized by having the same shape and protruding from each other.
