Clamping screw indiskutabel

Basically a fiffige solution, the holder can be any angle and can be wonderfully adjusted.
Unfortunately, you have not much of since the (cheap) plastic screw holding the ball joint, immediately turned the cautious tightening and the ball joint could not be fixed. The same technique without screws and thin cheap plastic instead of ordinary (metal -) - screws, the holder would be really great.

Update: The claim that the screw is exclusively made of plastic, I have to take. In the plastic screw is a small metal nut as an insert.
To what extent these dimensions a heavy 10 inches - Tablet withstand only can show the practice. It is possible that my retainer has been supplied defective, but for me the clamping screw is overtightened when first tightening. The adjustment principle are really good, it can be set at any angle.
