This is a general question, not for a specific application. It popped into my head while working on a minor home remodeling project last night. Has anyone had occasion to cut threads into a wooden hole using a tap?

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.
