Spare cover security screws

I see on the Ring website that plenty of spare parts are available for the doorbells, and are reasonably priced. I specifically want some extra, short cover screws, but all the spares kits come with all the stuff I don’t want/ need. I can buy them elsewhere, but at 5x the price, which seems stupid. I would like the option to buy maybe a pack of 5? Anyone know where that may be possible from please?

Thanks
