Why and when to use a screw insulator?

Screw insulators can be inserted into a housing to provide a bearing surface for rotary applications.
The flange on the screw insulator is used to locate the bushing when it is installed or to provide a thrust bearing surface.
Screw Insulators are used to prevent heat flow through the screw to other parts of the thermal assembly.
