if you tighten something to a certain torque, its always going to take more to loosen the same bolt. esp if that bolt has been left in place for a while. this is because oxidation occurs on the threads.. so there is some 'sticking' of the bolt and to the bolt hole. this applies to wheel nuts as well.. never over tighten them!
