I have a 1/2" x 20 UNF bayonet style electrical connector threaded into PVC.

The PVC is the standard gray material bought as a round bar off the shelf.

Mechanical constraints prevent using a locking nut or radial set screw
for retention.

Does anyone have any suggestions as to what chemical means might be
useful to lock or bond the (probably stainless) metal connector to the
PVC to prevent unscrewing?

Thanks.

If it has a hex area above the thread, perhaps you could plastic-weld
some more PVC material up around that to keep it from unscrewing.

Good idea - unfortunately its cylindrical.

Then I'd try epoxy.
