Default #27 screw size

Can someone please tell me what is the dimple die size of a #27 hole.
The instructions indicate using a flush screw in the #27 hole.
I want to know what dimple size is that?
I have a #6 dimple set and #8 dimple set, but I do not know if these will work;

Thanks in advance
Dave

This chart may help -

The #27 hole is a close fit for a #6 screw, so use your #6 dimple dies.

I'm pretty sure #27 is equivalent to a #6 screw (so #6 dimple die) Easy way to find out - try it on a piece of scrap material.

I presume the #8 die reference is a typo...

Thanks for your help. I was suspicion that a # 6 screw was correct, but I did not want to make another mistake.
