The invention discloses a torque control type nut. The torque control type nut comprises a nut inner bushing and a nut jacket, wherein the nut inner bushing is made of a material in which low-carbon steel is subjected to hot dip galvanizing on the surface, the nut jacket is made of a POM material, the outer border of the cross section of the nut jacket is in the shape of a regular polygon, the inner border of the cross section of the nut jacket is round, the inner wall face of the nut inner bushing is provided with a thread structure, the outer border of the cross section of the nut inner bushing is round, two symmetrical first ridges are arranged on the inner wall face of the nut jacket, at least one pair of grooves are formed in the outer wall face of the nut inner bushing, the first ridges are arranged on the axis of the nut inner bushing, the grooves are formed in the axis of the nut inner bushing, and each first ridge is arranged in the corresponding groove. A spanner special for the torque control type nut comprises a hand holding handle, wherein a first spanner head is arranged at one end of the hand holding handle, a second spanner head is arranged at the other end of the hand holding handle, a first sleeving hole is formed in the first spanner head, a second sleeving hole is formed in the second spanner head, the inner wall face of the first sleeving hole is a hole in the shape of a regular polygon, the second sleeving hole is a round hole, and a pair of second ridges are arranged on the inner wall face of the round hole. The torque control type nut and the spanner special for the torque control type nut have the advantages that bolts are prevented from getting loose, and the antitheft function is achieved.
