Tightening Torques - Stihl MS 460 Service Manual

Tightening Torques

DG and P screws (Plastoform) are used in polymer and 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 impairing the strength of the screwed assembly, providing the specified tightening torque is
observed.
For this reason it is essential to use a torque wrench.
