Steel nut threading onto aluminum receiver. Aluminum is much softer than steel, and the surfaces of the aluminum threads will slightly deform to conform to the steel threads. By tightening and loosening several times you assure that the torque you achieve will stay that way.

By tightening and loosening several times you assure that the torque you achieve will stay that way. Because of the different thermal properties of the two metals? One expands more than the other and will loosen up? Jay |
