Confirmat Style Connecting Screws
Origins: Europeans pioneered the development of man-made materials for use in
cabinetry. Medium Density Fiber Board (MDF) and Particle Board offer inexpensive
but dimensionally true and stable cabinet materials. These are often found with
a melamine plastic coating that facilitates cleaning and eliminates an extra
step in the finishing process. One down side to these materials is their
notoriously poor ability to hold fasteners.
Knock-down assembly is a trademark attribute of European cabinetry and it is
not uncommon for Europeans to move their existing cabinets to a new house.
Often, these cabinets even utilize a common hanging rail found in many European
homes. The doors can be easily removed and the boxes can be broken down for
transportation. Confirmat style screws are designed to be able to be removed and
reinserted without damaging the man made materials.
If you assemble melamine cabinets or work with Particle Board or Medium
Density Fiberboard (MDF), these unique fasteners have been specially designed to
make your life easier. The large diameter shoulder beneath the head acts much
like a steel dowel pin and locks the shank in position to minimize the
possibility of board failure. This creates a remarkably strong and stiff joint
that generally does not require glue. Screws require a pilot hole through both
pieces of material. Simply clamp the pieces together and drill with a
specialized 3-step drill bit. Specially designed screw caps are available to fit
a hole in the drive recess.

Confirmat Style Connecting Screws should be no farther apart than 5" or 128
mm on center and no more than 13/32" or 36 mm from each edge. Generally,
that translates to:
- 4 per joint in a 24"/600 mm deep base cabinet
- 3 per joint
in a 305 mm/12 deep wall unit.
