Description
Work tool for attaching and detaching stud bolts (can also be used for round bars).
Can be used for both tightening and loosening.
Three rollers grip the stud bolt from three directions, allowing for stable work.
Since the center is penetrating, it can be used for stud bolts that are longer than the wrench body. (When using a box wrench, etc.)
*Do not use if the gripping distance of the stud bolt is less than 20mm.
*The threads of the stud bolts may be damaged.
