Confirmat Screws M7 x 50mm Pack of 100
great for almost anything
Highly recommended for dry fixing, chipboard, mdf, even timber, great screws. You must not forget to pre-drill as suggested. It will then hold together anything. Fixed many items since i bought it, looks like i will need more soon.

Good for MDF
Agree with other reviews. You need to drill straight, drill a clearance hole at 6.5 - 7mm through the board, then pilot the MDF edge with 5 - 5.5mm hole and the and drill a bit deeper so the screw can't bottom out.
and countersink a bit.
Then it holds brilliantly and really this is the only screw that doesn't routinely split the MDF.

I made a full set of Kitchen cabinets with 18mm MDF and these. Huge holding power and if they need to be visible, they gives a neat, professional looking finish.
I found a 7mm countersunk clearance hole and a 5.5mm pilot hole worked best.

Used these to create MDF loft boxes out of 12mm MDF (to save weight and cost).
Yep, That's a 7mm screw into the end 'grain' of 12mm MDF without splitting. I used a 5.5mm hole a little deeper than the full length of the screw. Lining up the drill to make sure I didn't pierce through the side of the MDF was a precise job though!
