Tightening torques

DG and P-type (Plastoform) screws are used in thermoplastic and alloyed materials. These screws cut a thread
in the material when they are screwed in for the first time. The material is permanently deformed. The screws
can be removed and refitted as often as desired. The strength of the screw connection is not impaired if the spe-
cified tightening torque is maintained.
It is therefore essential to use a torque wrench.
