クランプ。 A steel pipe is held between the steel pipe clamping surfaces provided on the opposing inner surfaces of the main body metal fitting and the lid metal fitting, whose base ends are pivoted to each other, and the free end of the tightening bolt, whose one end is pivoted to the tip of the main body metal fitting, is In a steel pipe clamp that tightens a steel pipe by engaging the tip of a lid fitting and tightening with a nut, the tightening bolt is short enough so that its tip does not protrude from the top surface of the nut when tightening the steel pipe. At the same time, the nut that is screwed onto the tightening bolt has a rectangular head and a sheath integrally formed with the head, and the tip of the sheath has a threaded portion that is screwed onto the tightening bolt. Further, following this threaded part, a through hole with a diameter larger than that of the threaded part is provided in the sheath part and the head part, and the tip of the tightening bolt that is threaded with the nut and protrudes into the through hole. In the department,
A steel pipe clamp characterized by having a protrusion to prevent it from coming off.
