<p>PROBLEM TO BE SOLVED: To provide a tool for preventing rotation of a pipe fitting allowing easily preventing rotation of the fitting when connecting fluid pipes. SOLUTION: An engaging part 2 of the tool 1 is mounted on a head part 6 of a T-head bolt 5 and an operator grips a lever part 3. Even when the operator applies force to the opposite rotation direction of a tightening tool (wrench, etc.), put on the bolt 5, rotation of a pair of faces in parallel of the bolt 5 is locked by the engaging part, thereby the pipe fitting is not rotated even if the bolt is tightened to easily prevent rotation of the pipe fitting when connecting the fluid pipes without damaging the pipe fitting.</p> |
