I don't use the push in ones.
The kind I use have a coarse wood-biting thread on the outside. I use a drill half a millimetre under the specified size so as to get a really good fix, though if into a hard hardwood the fitting can break up instead of screwing in.
I like them because you can't tell from the outside that you haven't used a woodscrew, and you have, in effect, bolted something into timber.
I would also build in a bit of "give" into the assembly - you cannot make a wood on metal system as rigid as metal on metal, so go with the flow and put a thin piece of rubbery stuff between the two. The joint will last longer, whilst still providing stiffness.
