The above instructions must also be observed for concealed fastening without visible screw heads with the Sihga DielenFix system. In the following we explain how a wooden terrace is screwed with Sihga DielenFix.
Simply place the Sihga DielenFix with the integrated assembly stop on the back of the plank and screw in the enclosed BohrFix system screws
Repeat this process on each additional decking board, offset to the side.
Then fasten the board to the substructure with the BohrFix (28 mm long) that is also included. With the starting board, the DielenFix can simply be turned horizontally by 180 degrees and the integrated assembly stop pressed flat so that the board can be fastened as close as possible to any wall edge.
After the first board has been screwed to the substructure, simply insert the following board. Do not screw the new board on the inserted side!
Then just screw to the substructure on the side that is still free, again with an enclosed BohrFix system screw - done!
The first or the last plank is fastened with a partial visible screw connection. To do this, the stop is removed from the DielenFix and then the DielenFix is screwed on flush with the side wood surface of the plank. The board is then fastened by screwing hardened stainless steel screws into a pre-drilled and countersunk hole from above.
