I was hoping they would fit my Harley's hard to reach nuts and bolts. There is no spring on the adjusting jaw and the rubber coating makes it too thick to work in hard-to-reach places.
Pros
Strong practicality: easy to carry, automatic adjustment technology. Just a tool! This double-sided wrench is suitable for screws and nuts of any size. For pipes, screws, nuts, ideal for drilling, woodworking, machine building and gardening.
