To provide a screw member capable of performing management of fixation strength without complicating a structure of the screw member.SOLUTION: A screw member unit 10 includes a main body male screw part 13 which is provided on the shaft direction tip side of a main body shaft member 15 forming a shaft shape and is inserted into fixation object base material C such as concrete, a rear end male screw part 12 provided on the shaft direction rear end side of the main body shaft member 15, a torque management member 20 made of material different from the main body shaft member 15 and a torque management member connection part 11 which is provided on the main body shaft member 15 and attachably/detachably connects the torque management member 20. Therein, the torque management member 20 includes a first member 21 relatively non-rotatable around shaft with respect to the main body shaft member 15 in such a state as to be connected to the main body shaft member 15, a second member 22 capable of inputting a torque for management for managing a fixation strength to the fixation object base material C of the main body male screw part 13 and a managing fracture part 23 which is provided between the first member 21 and the second member 22 and fractures the first member 21 and the second member 22 with an input of the prescribed managing torque.SELECTED DRAWING: Figure 1
【課題】ネジ部材の構造を複雑化することなく、定着強度の管理を行うようにする。【解決手段】軸状を成す本体軸部材１５の軸方向先端側に設けられコンクリート等の固定対象母材Ｃ内に差し入れられる本体雄ネジ部１３と、本体軸部材１５の軸方向後端側に設けられる後端雄ネジ部１２と、本体軸部材１５とは別部材からなるトルク管理部材２０と、本体軸部材１５に設けられトルク管理部材２０を着脱可能に接続するトルク管理部材接続部１１とを備え、トルク管理部材２０は、本体軸部材１５に接続された状態で本体軸部材１５に対して軸回り相対回転不能となる第一部材２１と、本体雄ネジ部１３の固定対象母材Ｃへの定着強度を管理するための管理用トルクが入力可能な第二部材２２と、第一部材２１と第二部材２２との間に設けられ所定の前記管理用トルクの入力で第一部材２１と第二部材２２とを破断する管理用破断部２３とを備えるネジ部材ユニット１０とした。【選択図】図１
