Thanks.

I do not have access right this very moment, but I can tell you they do not look like machine screws, they almost look like brass wood screws.

They are screws for plastic, the ones that have a very coarse thread to bite into the plastic. Size and thread count I do not know though, but any decent sized pan or truss head screw could work.

Thanks for pictures!
As i see, there is no definite answer here. I saw here classical internal screws, but also this screws without notch for screwdriver...

The 'classic internal screws' are not for plastic.

The ones in my 5160 look like the pics Stone posted. Yours may well be the same type with a different plating. I doubt IBM actually made any of their fasteners. The difference in plating may well be due to the screws being sourced from different vendors.
