Because these machine screws hold hardware on the outside, I'll use caulk to seal out rain, and the caulk will eventually have to be replaced. Using an OEM-style headliner, the chromed bronze oval head machine screws go through the headliner, which is attached directly to the overhead frames, and there's an attractive beveled washer that they seat up against. But since I'm using Whisper Wall headliner, which uses a 1/2" tall track, and we added thickness to the outside with the kevlar and additional fiberglass layer when preparing the cabin top for paint. So the machine screws are all 1/2" or more too short.
I go through the options in the article, but one option would involve taking my collection of spare chromed bronze screws and bolts, cutting off lengths I need, and welding that to the OEM machine screws to make them the necessary length.
But before I do that, does anybody know a source for 5/16-18 x 5-1/2" or longer stainless oval head Phillips machine screws?
