Was skeptical whether an electric impact wrench may have enough power to solve-strength bolts. Had already anticipated that one eh first must solve with hand and the wrench is only a small relief with long screws. But thinking completely wrong !! Wheel bolts are absolutely no problem! Even with a chassis conversion to a car that had nearly 100,000 km on the clock and the screws have looked accordingly speak, he never strike! Once attached and the screws were immediately! I need it rarely (2-3 inserts a month) I can say with regard to the durability is not much. But for the purpose in the garage just perfect!
