Screwbolt TSM-ST
Application
Suitable for quick and safe fixation of Sikla Channels and pipings to concrete ceilings or walls. To be applied in dry rooms.
- Easy installation via self-cutting action of screwbolt threads into concrete
- Small edge and axial distances to adjacent fixings, due to low expansion pressure when installed
- Also fixes into pressure-resistant natural stones and different solid bricks (not part of ETA approval / guideline)
- Flexible use for high or standard load performances due to 2 anchoring depths
- For single fixings it is possible to additionally seal the drill hole with a special injecton resin against water ingress, prior to the fixing being installed and before the injection resin sets
- Fixings in isolated ceilings can be realised with the long versions of the TSM-ST
Installation
Screw in the bolt screw in pre-drilled pilot hole. The special thread guarantees a mechanical form lock with the base material. Fine adjustment of depth is possible if the TSM-IM screw is initially installed too deep.
