- Metric thread
- Self-drilling window construction screw for use in UPVC window construction
- For connecting UPVC profiles with the metal reinforcement (up to 2.5 mm) and for securing fittings on profiles with metal stiffening (up to 2.5 mm)
- Greater load capacity threads with thin sheathing iron
The risk of forced advance with large distances between plastic and metal bracing is minimised by the flat, metric thread
If forced advance occurs, the drill tip may break away or the screw break during application.
