I had never heard of a torque multiplier specifically for lug nuts until a friend mentioned it. I used the tried and tested wrenching method with a 6ft pipe to loosen the grommets on my RV and I needed something I could easily carry in my onboard tool box so I ordered this. We used it yesterday to take the front wheels off my Freightliner and it did the job perfectly. My friend saw how easy it was to work and decided to buy one for himself. This set comes with sockets ranging from 24mm to 38mm allowing it to be used on a variety of vehicles. Definitely 5 stars in my book!
