Why are these so small!!! Wtf

Anyone have experience with these APD PDB500's? First time using one and the mounting holes are 3 times smaller than any other one I've used. I can't get any iso grommets in it. I had to single point thread a custom bolt on the lathe just to mount it. Am I missing something? They didn't include any grommets or screws with it at all

You don't need grommets for a PDB.
Looks like standard M3?

Agreed. Next time you throw away an old laptop, rob it of all the screws and save 'em.
