Abstract
A method for tightening a screw for fastening a construction panel to a support of the construction panel, in which the fastening screw is screwed through the construction panel and then through at least part of the support, includes a monitoring of a change over time of a tightening torque of the fastening screw, with determination of a first maximum torque value and then of a second minimum torque value, and after determination of the second minimum torque value, a stoppage of the tightening of the fastening screw for a torque value, termed stoppage value, corresponding to a third maximum torque value or being determined after an occurrence of a third maximum torque value.

A method for tightening a screw for fastening a construction panel to a support of the construction panel, in which the fastening screw is screwed through the construction panel and then through at least part of the support, the method comprising:
- monitoring a change over time of a tightening torque of the fastening screw, with determination of a first maximum torque value and then of a second minimum torque value, and
- after determining the second minimum torque value, stopping the tightening of the fastening screw for a torque stoppage value, greater than the first maximum torque value, the torque stoppage value corresponding to a third maximum torque value or being determined after an occurrence of a third maximum torque value.
