The wood construction screw with double thread is used primarily for fixing on-rafter insulation with pressure-resistant and non-pressure-resistant insulation materials.
Due to the high pull-out resistance, it can also be used for many other applications in timber construction.
In damp rooms and outdoors, non-corrosive materials must be used for mounting (DIN 18360, Section 3.1.4.1).
The user is responsible for design considerations.

Installation must be carried out in accordance with the approval certificate!
