It seems like a good hardwood, like oak or maple, would take the
threading better than pine. If you don't torque the bolt down too
tightly, or remove and reinstall it too frequently, it shouldn't wear
out the threads for a long time. Or you could use a Teflon bolt. Or a
wooden one, if there is such a thing.



Do you think that a bolt in a threaded hole would last longer than a
screw which is removed and reinstalled infrequently?

Another option not yet discussed is as follows:



1 - Drill a hole through the face of the wood just big enough to

accept the shaft of your bolt.

2 - Bore a hole on the back side of the wood large enough to accept

the correct size nut for the bolt.

3 - Coat the threads of the bolt with Vaseline, slip it through the

hole and into the nut.

4 - Pour epoxy around the nut to secure it in place.



The Vaseline coated threads will allow you to remove the bolt after

the epoxy cures. When viewed from the face, all you'll see is a small

hole in the wood, but there will be a nut behind it to accept the

bolt.

This is a common method. Usually one mixes glass microspheres with the
epoxy. Or you can just use a bit of Bondo.

A while back I was building something that needed a heavy wooden base. I
also needed to bolt and unbolt items to the base each time we set it up.
Instead of using regular nuts, I cut 3/4" steel rod into 1" lengths, tapped
them to accept bolts and then used the method described above to epoxy them
into the board. Between my son and I we made about 50 round nuts out the
rod. Once things were bolted down, it was a heavy, sturdy structure.
