grub/set screw sizes??

[Debadoo]

I'll apologize in advance if my technical/scientific terminology is too much for some of y'all.

I've looked and can't find if it's listed somewhere. I need the sizes please for the set screws, grub screws, whatever ya call em...... the kind without a head but a hole in em, where ya use the allen key/wrench thingy for the RM5 and for the RM8

Also, my derringer clone is not an RM8, but am hoping the screws will be the same size, what do y'all think? I know they could vary, but is there a pretty good chance they'll be the same? I think mine came from cigreen maybe.

Lastly, best place to find the critters? If y'all could gimme links to the two set/grub screws I'd be most grateful. I know the places you get em have just shy of about a gazillion screws

thanks so much!! Hugs to my Reoville fam!

I don't know the sizes you need, but I have some - got my first ones from Fat Daddy, and then a batch when fasttech started carrying them. FatDaddy has a set of 6 each, three different sizes that's handy...

thanks hun, I'll check that out. Do the fatdaddy ones tell you which is which?

You mean what do they fit? No...
It's just a little "spares kit". It says:

Set of (6) M3, (6) M2.5, and (6) M2 hex keyed stainless steel grub screws. Very hard to find in SS!!! Even my regular factory refused to make it.

I'm pretty sure SOMEONE will know what size goes in a Derringer!
And I'm pretty sure it's one of these sizes...

no, I meant do they tell you if the bigger numbers are the bigger screws or vice versa. So you know which screw is which size? They don't on the site, thought I'd ask you before I sent a contact to them in case you knew

My notes say the Derringer grub screws are 4-40 x 1/8" (18-8)
These you may be able to find at a good hardware store
The metric sizes FD has are what fit most attys.

Found some on ebay:
#4-40 x 1/8" - Qty 10 - 18-8 Stainless Steel SOCKET SET / GRUB SCREWS Cup Point

Ah, then there's this. 4-40, 1/8"
I haven't bought these, but saw it somewhere, specifically recommended for a Derringer...
