The Würth #8 x 1-1/8" flat head assembly screw is a production-oriented fastener built for cabinet shops and millwork operations that drive screws by the thousand. A 1-1/8" length fits common joinery scenarios in 3/4-inch sheet goods and cabinet panel work, and the screw's combination of turbo thread, lubricated finish, and combo drive keeps installation moving with less resistance and fewer bit changes.
At 1-1/8", this screw reaches through one layer of 3/4-inch panel stock and bites into the substrate behind it, which covers a wide range of cabinet carcass and panel joinery situations. It works well for joining cabinet sides to shelves, attaching back panels at the perimeter, fastening drawer box components, and securing interior dividers where you want enough thread engagement to hold the joint firmly without over-penetrating thin secondary material. The length also suits hardware backing blocks and light blocking work inside frameless cabinet boxes. It is an interior fastener, so keep it on dry, climate-controlled applications.
The combo recess accepts a #2 Phillips or a #2 square bit in the same head. On a busy assembly line where multiple operators are working, that flexibility means whoever picks up the screw can drive it with the bit already in their tool. The turbo thread's wider pitch and aggressive cutting geometry move material faster per revolution than a standard coarse thread, which adds up across thousands of fasteners. The lubricated finish works alongside the thread design by lowering surface friction during seating, which helps protect both the screw head and the driver bit during sustained production runs. The flat head's underside nibs mill into the panel face as the screw approaches full depth, producing a flush or just-below-flush countersink in particleboard, MDF, and softwood without pre-countersinking.
Cabinet shops running 32mm system frameless boxes, RTA component manufacturers, millwork teams building interior casework, and finish carpenters assembling site-built cabinetry are the primary buyers for this SKU. The 8,000-piece box quantity reflects that. A smaller crew doing a single kitchen install will work through it over multiple projects; a production shop will cycle through boxes steadily. The combo drive is particularly useful in environments where the crew uses a mix of driver bits and bit changes need to stay rare. Because the sharp point is optimized for engineered panels and softwoods rather than dense hardwoods, this screw is most at home in particleboard, MDF, melamine, and pine-based cabinet materials.
Yes. The combo recess is machined to accept both a #2 Phillips and a #2 square bit in the same opening. No adapter or change is needed — just pick up whichever bit is in the drill and drive.
The sharp point self-starts cleanly in softwoods, particleboard, and MDF. For dense hardwoods like maple or oak, a pre-drilled pilot reduces the risk of splitting, especially near edges. This screw's turbo thread and sharp point are best matched to engineered panels and softer wood species.
The lubricant lowers friction between the thread surface and the material as the screw drives. In practice this means less resistance at the driver, less heat build-up on the bit, and a lower chance of stripping the drive recess during a long production run.
In most wood-based panels — particleboard, MDF, softwood — the nibs mill their own countersink as the screw seats. A separate countersink step is not required for those materials. Harder substrates or finished face veneers may benefit from a light pre-countersink to keep the surface clean.
No. This is an interior assembly screw. For outdoor work or pressure-treated lumber, choose a fastener rated for exterior exposure and ACQ compatibility.
When the length fits the joint, the drive accepts the bit already in the tool, and the thread pulls through panel material without stalling, the fastener stops being a variable and the work moves forward. That is what the 1-1/8" Würth assembly screw is designed to deliver across a full box of 8,000.
