Claims

[Scope of utility model registration request]

In a socket for a nut runner having a polygonal fitting hole into which a bolt head or a nut is fitted, a recessed groove perpendicular to the axis of the socket is formed on the distal end surface of the socket, and the fitting hole is formed on the bottom surface of the recessed groove. The matching holes are opened so that a pair of opposing hole wall surfaces match the groove wall surfaces on both sides of the groove, and the groove wall surfaces are inclined outward in the groove width direction toward the axial direction of the socket. A nut runner socket characterized by forming a surface.
