Ruger Rings screw size

[FatCatsDad]

I bought a set of Ruger Rings for an M77 but when they arrived the slotted heads were f you c kayed..

Does anyone know what size they are ? so I can start hunting for a set of 8 replacement screws

I bought replacement Torx head screws for Ruger rings from Brownell's - #6-40 tpi x 1/4" T-10 Torx head. Brownell's part number is /was 080-924-464 for baggie of 12 screws. They are not a perfect match to original Ruger Torx head screws - but replaced in sets of 4, they looked fine

Ruger sells full replacement sets. I’ve bought them from snapshots in the past and they were pretty cheap as far as gun related screws go. I think the pack of 8 screws was something like $10.
