Thanks for the replys.
Inner layers really dont know... also because others pals are running the PSU using screws throught the PCB..
But, im going to try, using another coin of screw.. and then post again
Thanks all!!
They may just have been lucky, dependant on exactly where the holes were drilled, size of the hole & size of the screws etc? What you have said though is that with the screw out there is no short & with the screw in there is a short. So either there is a problem with your cables or with the screws. Have you tried with just the screws & no cables?

if the bolts you used are shorting inside the holes the nylon screws should not.
