The Würth #8 x 1-1/8" Washer Head Assembly Screw is a lubricated, turbo-thread screw built for cabinet box assembly, panel joinery, and furniture production work where a low-profile head and smooth driving matter. The washer head, milling nibs, and combo drive make it a practical choice for production shops running high volumes of similar assemblies.
At 1-1/8", this screw is sized for situations where a standard 1" falls just short but a 1-1/4" goes deeper than needed. That range covers single-layer 3/4" panel attachment with modest embedment, thin face-frame overlay work, and hardware-backing applications in melamine or laminate-faced panels. It also suits drawer box assembly in 1/2" material where a longer screw would risk blowing through the opposite face. Cabinet shops assembling RTA carcasses or joining shelf standards to panel sides will find the length practical for those repeated, controlled-depth connections.
The washer head spreads clamping load over a larger footprint than a flat or pan head, which helps prevent pull-through in lower-density materials like particleboard and MDF. The milling nibs on the underside of the head cut into the surface as the screw seats, producing a cleaner bearing surface without a separate countersink step. The lubricated finish reduces the torque needed to drive the screw to full depth, which matters on a production line where the same motion repeats hundreds of times per shift. Together, these three details mean the screw goes in quickly, sits flat, and stays there without overdriving.
This screw is designed for shops assembling cabinets, casework, furniture components, and similar wood products at volume. The combo drive keeps the line moving when bit selection varies between operators or stations. The turbo thread and lubricated finish reduce driving effort in the materials most common to cabinet production: particleboard, MDF, melamine-faced panels, and softwood. For smaller residential projects or one-off builds, the same properties make the screw easy to drive by hand with a standard cordless driver and whatever bit is on hand.
Yes. The combo drive recess accepts a #2 Phillips bit or a #2 square bit. Either works in the same head, so no special tooling is required.
The lubrication is applied to the thread and point surfaces to reduce driving friction. It helps the screw reach full depth with less torque, which is especially noticeable in dense materials and during repetitive driving.
The washer head sits above the surface rather than countersinking flush, so it is best suited for interior panel joints, cabinet interiors, and locations where the head will be covered or is not a finished surface.
Yes. The turbo thread, lubricated finish, and sharp point are all well suited to particleboard and MDF. The washer head distributes load to reduce pull-through in those lower-density materials.
This screw is suited for interior woodworking and cabinet assembly. It is not positioned for outdoor or high-moisture environments.
The 1-1/8" Würth Washer Head Assembly Screw gives production shops and installers a reliable, fast-driving option sized for the thin-stock panel work that fills most cabinet assembly days.
