CVA Sight hole grub screws- Are these important?

[RobRed]

I noticed my CVA Accura came with a packet of little set screws. Nothing mentioned about these in the manual from what I could see. A quick google lead me to the CVA website where they are sold as Sight hole plug screws.

Are these important to instal? Do they just keep grime out of the blind holes?

Yes, they'll keep dirt, water and other crud out of the holes.
I'd install them. Only takes a minute or two. It will keep those hole threads in good condition.

I’ll put them in with a little anti seize
