- Drill 4 holes with a diameter of 12 mm (0.5 in) and a depth of 130 mm (5.1 in) into the concrete. Note the bolt pattern and dimensions.
- Fasten the M10×40 wedge bolts to the lower ends of the foundation screws (4 each).
- Place the wedge bolt and foundation screw combinations into the holes, with the wedge bolts down, and hammer the protruding threads down.
- Tighten the foundation screws a few turns to attach the wedge bolts to the hole walls.
Clear the foundation of extra parts before continuing with the installation.
