I have assembled a Table Micke for the 1st time ...
but I have some screws I want to remove. or didn't fit well (shld have tighten all screws more), 110126, 103430, 110630
the look like below
they are put in like below
Those don't actually screw in. They just press in the hole and then tighten to the connecting bolt attached to the opposing piece of wood. Just loosen the cam so you pull the connecting bolt out. Should be fairly easy.
After that, if you still need to get the cam part of the fastener out, it should just fall out. If it doesn't, I just stick a small screwdriver in the connecting bolt hole and lift it up.
