Understanding mounting hole size for front panel

[golkit1]

I try to design my first stuckable pcb that will contain 3 pcbs together.

here is my 3 parts pcb: (right hand side is the front panel drill holes)
I looked on the jack datasheet and I understand 6mm hole is needed: Thonkiconn – 3.5mm Jack Sockets – Thonk – DIY Synthesizer Kits & Components

does it make sense the way my layout is? it seems to me that the hole is too big? and there will be no space for nuts on the jacks?

I wrote 6.1mm in the radius option in kicad instead of 3.05mm . this was my mistake

Make sure you use the MAX tolerance, plus some additional tolerance due to registration and solder position
