DIN 985 is standard issued by the DIN in Germany.
In this case it is for a simple nut found here.
This is a follow up to this question from bicycles.
I Googled DIN 985 but found nothing comprehensible.
These nuts and bolts are to secure aluminum so I tagged this aluminum but if there is a better tag please edit.
I would drill your holes for the rack through your cabinet, then drill some counter-sink holes on the inside of your cabinet so your bolts are flush with the inside. You can find some flat headed bolts to use for this at any hardware store. Have the head of your bolt on the inside of the cabinet and secure it with a lock washer and nut. You should not need anything too thick as far as bolts go for this. You idea on how to mount them will be fine. The bad thing is that now you will have holes in your cabinet, so if you do not like it or if you want to remove it, you have just ruined your cabinets in a sense.
Use 1/4" Cut Tacks instead: (Amazon)

DIN 985 appears to be the old name for what is now called ISO 7040 Which describes hex nuts with a nonmetallic insert, stating their dimensions etc.
If there a likelyhood of exposure to dampness I would reccomend using aluminium or stainless steel fasteners.
