Kitchen cabinet

[Alwayslearning22]

I’m planning to install two kitchen cabinets in my utility room from Ikea. 

I have some concerns about the brackets that came with it.  
It’s just two screws per cabinet one In each corner. 

I’ll be mounting it onto my party wall which has service batons  which only seem to be 30mm deep.

If I were to use 50mm screws which would give me a little over 30mm penetration into the batons, be enough to hold the cabinets securely? 
 
or should I cut the wall open and add some 18mm ply?

Just use 80mm frame fixings, drill a hole through the batten into the block behind and knock the frame fix through. Just make sure the plate hole is big enough for the head of the fixing

Thank you for the reply Peter. 
I should of said it’s a timberframe house. I know the stud would behind the plasterboard and soundblock. Should I drill through all of that to hit the stud? 
 

would it affect the sound proofing and vcl ?

If it’s sheathed with OSB and you know where the battens are then just use 5x60 screws - plenty strong enough and it won’t affect the VCL as you’re filling the hole you create with a screw.

If I use 60mm screws I will just get through the service void battens and slightly into the pink plasterboard. 
Would I need to use 80 mm screws? To get through to the stud wall? 
It gives me anxiety thinking about screwing such long screws through into my party wall.

As long as they aren't coming out the other side of the timber, its ok.

Treat yourself to some high quality screws.
