- For easy installation of wooden beams / sleepers- Adjustment process is simplified so that no assistance from a second person is required- How it works:- Create the drill hole and prepare the drill hole in the wooden beam- Clean the drill hole- Bring the adjusting disc together with the concrete screw, so that the moulded washer of the concrete screw fits into the recess of the adjusting washer- Set the concrete screw with an impact screwdriver to the specified torque- Place a second adjusting washer with the countersink facing downwards on the already installed concrete screw- Fasten the adjusting washers to the timber using standard screws with a flat head- Now the concrete screw can be easily loosened again and the beam can be aligned and relined or underpinned as required. - After adjustment, tighten the concrete screw again- Optional: Once the adjustment is complete, the upper adjustment disc can be removed and used for the next installation
