Applications
- Fastening of pre-painted double-skin profile on the lips of panels with insulation without compression.
Advantages
- Special screw to prevent the insulation from being compressed, as the spacer cone limits the tightening to 40 or 60 or 80 mm depending on the model.
- Its double thread avoiding deformation of the outer skin when tightening.
