With a little bit of preparation and a general understanding of the objective, installing cabinets is really not a big deal! Generally speaking, the objective is to get the cabinets securely attached to the building with level work surfaces. Ideally, the installation should ensure that work surfaces will stay level for many years, as well.
In most applications, cabinets have a 3/4" hanging rail and the wall will be 1/2" drywall over studs. Install 2x6 blocking between studs during wall construction to make attachment of the cabinets significantly easier. Install base cabinets on blocking made of plywood strips rather than the standard 2x4 base to keep work surfaces level as the structure ages. Plywood is dimensionally stable, whereas framing lumber can shrink considerably as it dries out − as much as 3/16" in width!
Use 10 x 3 screws when attaching cabinets to wall studs, or use 2-1/2"L screws when attaching to 2x6 blocking. We carry several suitable fasteners for this purpose (but you already knew that, didn’t you?). For a finished appearance without resorting to screw caps or plugs, the 10 x 3 trusshead cabinet-hanging screw is prefinished with a clear-zinc-plated, white or sand head. The large bearing surface of a 10 x 3 round-washer-head screw helps prevent crushing of the hanging strip, and the screws are available in a range of finishes. To match the cabinet interior more closely, our #10 flat heads can be driven flush and covered with screw caps or driven through a trim washer (which also increases the bearing area). Clear-zinc-plated, yellow-zinc-plated or stainless steel screws are recommended for kitchens and baths to minimize discoloration.
The method used to fasten cabinet boxes together depends largely upon the type of cabinets used.
Face frames are generally joined by attaching the stiles together using #8 flat-head steel screws. The screw should penetrate a minimum of 1" into the second stile. The hole may be plugged for a finished appearance. Once the faces are flush and tight, simply predrill the pilot hole (7/64" to 1/8"), flip the drill guide out of the way and drive the screw tight while the cabinets remain clamped in position.
European cabinet boxes are joined with panel connecting screws, which fit through predrilled 32mm system shelf pin holes on the inside of adjoining cabinets. Once the hole for attachment is selected, simply drill through with a 8mm bit, align the boxes and slip the connectors in place. simple.
