Is there a standard type s***w for an inground pool light?

Question

I am missing the s***w for my pool light and the light is not flush with the wall at the top where the s***w should be. The light works great but very loose. What size should I get?

I dont want it to rust either. I see where it should go at the top but I dont want to break anything. I dont know the brand of light.

Any help would be great. Thanks

Answer 1

A pentair light  is the most common light out there.Its known as the amerilite which used to be made by american products. This s***w should be available at any pool store.Its not really a special thread,but it has a tapered end which really helps get the s***w centered,especially when you are fighting the bouyancy of the light and holding your breath underwater!

Answer 2

look to see if the cover is counter sunk of just flush,if its not flush get a countersunk s***w,also use a stainless steel s***w.they dont rust.
