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.
I've spent ages on these as the plastic slot plug doesn't just pop out with the screw driver. Here's what works:
Turn the plastic plug left or right with a screw driver until you feel that it's loose. (It's not screwed in, but it's like a safe lock - 270 degrees of it blocks the screw it's hidding to make it tight. The remaining 90 degrees when lined up with the screw inside will act as an open door and not be gripping the screw.) Now potentially you may be able to pop out the plastic, but in my case I couldn't.
So on to the second step. I held the adjoining piece of wood (side of shelf) and softly hammered it away from the shelf (with the plugs). Suddenly there was a gap and I could see the metal screws. One side came away with ease, but the other was still caught. So while simultaneously lifting the adjoining wood, I moved the plastic "plus" with a screw driver. Boom! I loosened it and away it came!
Finally! after much swearing and screaming it worked! This did it for me!
First make sure that it is not in a locked position (ie remove or lift the bolt attached to the side if any). Then simply screw a screw into the X-area of the fastener from outside, just 1-2 mm so that the screw kind of locks on to the fastener. Then you can wiggle it out.
Pro tip: Do not use a screw driver machine or you risk destroying the fastener (as the guy in the video above accidentally does)
