Why the HECK are lamp finial threads 1/4”-27? It’s such an oddball when 1/4”-28 I would consider the “normal” fine thread standard. Is it some other carryover from the gas era? The rest of lamp threading is based on plumbing threads.
Lamp finial thread standard is weird.

I can't answer the question but I can sympathize. lighting fixtures are beyond frustrating to repair/modify, especially for the things this industry wants them to do. Designer wants to hang a floor lamp from the ceiling and you gotta rebuild the whole lamp because you can't find a compatible bolt with the threads in the doohickey.
