Are they uv resistant rated. need them for a boat so the ones i use needs to be ultra violet rated.

Don’t know 100 percent certain that the material is UV resistant. My application is indoors for this particular product, with minimal sun exposure through “e” (Reduces UV transmission) glass. I have used “similar”caps (Home Depot) to protect kids from protruding screws on outdoor equipment and those hold well to weather extremes ice and continuous hot sun. And likely made of the same plastic material.

What is the screw size both "S" & "M" ?

Tony, the screw size for S can be a #5, #6, and or a #8 Screw. The hole diameter for the screw cover caps is 4MM or 0.16 inch. The screw size for M can be a #6, #8, and or a #10. In Metric, it would be a M3, M4, and or a M5. The M size hole diameter is 5MM or 0.19 inch. Edward M.

Is the 0.51 the inside measurement or the outside. If it’s the outside what is the inside measurement?

0.51 (13MM) is the outside measurement. The inside measurement is 0.16 (4MM)

Can M6 screws/bolts fit through these?

Screws yes, bolts no... unless they were recessed flush heads.
