Technical data & dimensions
Final drilling depth for GTS Screws
To ensure that the GTS sits securely, we drill a few millimetres deeper than the actual screw-in depth. This additional clearance is already taken into account in the drilling depths we specify:
Auger drill bit Ø 36 mm:
- GTS Allstar 2.0 (20.0 cm) + Forstner-Pin-Combo (8.0 cm)
- GTS Top 2.0 (17.0 cm); old GTS Top 1.0 (15.0 cm)
- GTS Friend 2.0 (17.0 cm); old GTS Friend 1.0 (14.0 cm)
- GTS Free 2.0 (14.0 cm)
- GTS Side (14.0 cm)
Auger drill bit Ø 24 mm:
- GTS Safety (13.0 cm)
- Strut Connector in End Grain (20 cm)
Important note for softwood (spruce, poplar, etc.)
After the GTS has been screwed completely into the tree, loosen the Hex Nut again to slide the accessories onto the shank. To prevent the GTS from turning backwards in very soft wood, the screw must be tight:
- Grease the Hex Nut thoroughly before screwing in the screw.
- Use PU glue (e.g. Beko 15) inside the drill hole.
- Be careful not to over-tighten the screws when screwing them in.

Tips for installing GTS tree bolts
The right cordless screwdriver
To pre-drill the large holes for the GTS in the tree, you will need a powerful cordless screwdriver:
✔ A long additional handle is essential!
✔ Drill chuck Ø 11 mm required
✔ Power for softwood: > 80 Nm, 4Ah, 18V
✔ Power for hardwood: > 120 Nm, 4Ah, 22V
Tips for pre-drilling
✔ Drill at a low speed (gear 1 or 2) to give the drill bit more power.
✔ Be sure to use an extra handle for more control and safety.
❌ Do not use smaller drill bits for pre-drilling, as this will prevent the self-tapping tip of the auger drill bit from working!
Safety during installation
⚠️ Caution: Risk of injury to the wrist due to sudden kickback!
✔ Only drill with an extra handle
✔ Always ensure you have a firm footing
✔ Secure yourself to the tree
✔ Make sure that no one is standing below you
This will make your treehouse construction site a complete success!
