Confirmat screws are designed specifically for use in furniture & carcass assembly.
They have a very coarse, sharp angled thread which helps the screws to cut into MDF & chipboard materials.
Confirmat screws are particularly effective for right angle butt joints. There are specific Confirmat drills which are recommended for pre-drilling.
This will ensure the holes are the perfect size and will stop the wood from splitting.
Confirmat screws are widely used in flat pack furniture.
