Tightening Torques

Plastoform screws are used for polymer components and “DG” screws for light metal components. These screws form a
permanent thread when they are installed for the first time. They can be removed and installed as often as necessary
without detrimentally affecting the strength of the screwed assembly, providing the specified tightening torque is
observed. For this reason it is essential to use a torque wrench.
