Backup wrench Backup wrench

The hands-free magnetic backup wrench is the easiest way to stop the nut from rotating. This kind of wrench is simple to operate, easy to use, and can be operated independently by a single person. The open-ended backup wrench is particularly useful for tight clearance conditions that cannot be completely installed with an Allen wrench. The backup wrench tool can lock the safety splint to ensure that the tool will not fall off. It is also equipped with the patented embedded magnet technology of the standard hands-free magnetic backup wrench. When tightening or loosening the nut, the low profile back-up wrench prevents the nut on the other side of the stud from rotating.
