The threaded fastener has a head end, a far end and a hollow core between the head end and the far end. A reference rod is mounted inside the hollow core. The reference rod has an anchor end attached to the far end of the threaded fastener and a free end extending in the head end. A flexible contact element is attached to the free end of the reference rod and is movable in the head end of the threaded fastener along a displacement path upon elongation and relaxation of the threaded fastener. Switch elements are mounted in the head end of the threaded fastener along the aforesaid displacement path of the flexible contact element. The switch elements are making calibrated contact with the flexible contact element upon a movement of the flexible contact element during a movement of the flexible contact element along its displacement path.
