Sealing screws for light

[Puppiesonacid]

I can't seem to find a 2 inch screw with a little gasket in the middle to pull the ring tight that seals the light fixture.

I am replacing most of the light. IE seal and bulbs... I have one screw with the nut on it, but no tiny rubber gasket in the middle, and the other is missing the nut.

I am not sure it needs the gasket. But not sure since neither has one.

Just wondering if anyone has a site to find them on? I sure can't...

Pentair 78458100 Amerlite 120V, 500W, 50' Cord with Stainless Steel Face Ring Pool Light

Looks similar to this for the fixture
Thanks

That screw, I believe, is a special bi-metallic screw that is used to help reduce corrosion between to disparate types of metal. That's gonna be tough in the hardware store.....I would get pentair involved to get the one you need.

I don't think the "gasket" feature is important....I think it's more of a "washer" to give a nice, snug fit.

If any washer will do, i can get those and a new nut... i have the screws... though one is rusted a little... guess i will make a call.

Thanks
