Rok 100 Pack Hardware #6mm x 13mm (1/2) Pozi Cross Flat Head Euro Screws Type B Point Fasteners

These are a perfect answer for attaching a drawer slide to predrilled 5mm holes in a cabinet. Work great and are excellent and flush with the drawer slides thickness.

just the right length for what I used them for see above

I had no idea that these things existed. Great solution to fastening things to thinner materials.

I have some very large kitchen drawers that needed more support on the rails, these screws fit perfectly and are designed for use in press board and worked well.

Used these for particle board applications where regular screws tend to break down the binding glue and come out more easily. Important not to put in too tight and to pre-drill holes exactly to recommended size if possible. They are good for shear loads (such as drawer slides and some shelving, but should not be used for tension joints). You can set them with a regular Phillips head, but a Pozi head will give you a better feel for the correct torque. I have no experience using them in MDF, but think they would be OK. I prefer regular screws for solid woods and plywoods.
