To improve efficiency of construction by eliminating the need for measuring a resistance value of a reinforcing steel connector.
An inorganic grout mechanical joint 10 comprised of the reinforcing steel connectors T to connect in series the main reinforcing steels 3 arranged inside a column of a building includes a coupler 11 to connect ends 3a of the main reinforcing steels 3 and a locknut 12 to fasten the coupler 11 from both ends, eliminates a rust-proof coat of both end surfaces 11a and 11a of the coupler 11 and end surfaces 12a facing the coupler 11 side of the locknut 12, and contacts the end surface 11a of the coupler 11 with the end surface 12a of the locknut 12 surely by surface treatment in a state with the locknut 12 fastened to the coupler 11.
