Screw, Locking W/ Gum Washer - 79104800
The pilot screw has nothing to screw into inside the niche. There is a hook at 12 o'clock and the screw is at 6 o'clock .
Hi, Gerry. Niches are designed where the pilot screw is at 12 o' clock and the hook is at 6 o' clock.
My stainless steel face ring is getting some light surface rust. Could the damaged gum washer be causing this. What is the gum washers purpose and is it really necessary to have one?
Hello, Yes the gum washer is used to set the face plate, you could be experiencing the screw rusting which does happen.
what side of the ring does the gum washer go on for the pilot screw
The Locking W/ Gum Washer Screw (79104800) is installed with the washer on the screw, so the washer will be on the outside of the Face Plate.
Will this part screw into the gunite niche in an in ground pool to attach a pool light? My light keeps falling out even with stainless steel screws to hold it in place.
This locking screw with washer is the screw used to keep the face ring in place w/ the housing of the light. This screw was designed to fit into certain Pentair lights. I cannot say for certain if this screw will fix your problem, even if the light you currently own is made by Pentair.

Pros: Works like original equipment
We needed to replace the light in the gunite pool in our new home. When pulling out the fixture, we noticed that the pilot screw no longer had the washer, and ordered a new one. It arrived in a couple of days, and was a perfect replacement part.
