Bought an IKEA side table(listerby) today but it was impossible to install.Here is the installation instruction. If you look at the fifth step, one is supposed to use the tool IKEA provides to fasten the screw. However, the tool is tool long which makes it impossible to be rotated since the screw is sitting in a shallow hole as you can see. Any idea how I can solve this?
I recently purchased and assembled two of that exact same product (except mine are the dark brown color) and had no problem with the step 5.
If you look closely at the small IKEA tool it has more than 6 lobes in the tool opening so it can engage the hex nut in multiple positions. I also noticed that since the handle of the tool is offset to one side of the wrench end it is possible to remove and flip the tool over on each stroke of securing the legs onto the Listerby end table.
In the end I am very happy with the end tables. I also assembled the companion coffee table as well.
Yes, you are turning a 6-sided nut, but your wrench is 12-sided. That is a standard trick done with wrenches, so you don't need 60 degrees of swing, only 30 degrees.
However, it helps to physically compress the things going together (to remove all slack) and finger-spin the nut down as far as possible. That way you need to reach in for fewer turns.
If you have stripped the supplied wrench somehow, take a nut to the hardware store and get a box style wrench that fits it snug. Expect metric.
This is an open-box wrench, red dingbat on the open end optional.
Only the box end is useful here, due to clearances.
And make sure you are sticking that semi-circular spacer in there before it's tightened all the way. Do Not bottom out the nut without that spacer, or you'll need serious skills to rectify it!
