D-ring hole size and mps insert style 7 hole size

[NooB1Kenobi]

Ok Trying to wrap up my order and I am all but stuck on this last bit of info.
What is the hole size in the D-ring?
What is the hole size in the MPS insert style 7?
What I want to know is what size screw I will need.
Yes 1 screw is holding up my order.
Please let me know so I can spend some money.
Thanks!!

Why not get MPS insert style 12? The D-ring is built in.

The holes in Insert 7 are not threaded in any case. You'd need to thread them yourself with a tap.

Not sure if you placed your order yet or not, but i've found that the 10-32 button head screws work well with the D-ring. The holes in Insert 7 definitely won't be big enough though; you'll have to do some drilling and tapping if you're set on going that route.

Ok thanks. Wasn't sure if the 8-32 or the 10-32 would be big enough for the whole in the D-ring.
I don't care for the bulkiness of number 12 and I only have $99.25 on the card to spend for this and with adding that last screw I am at $99.23 including shipping.
Thanks again!!
