Tightening Torques

Plastoform screws are used for polymer 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.
