The Würth #8 x 1-3/4" flat head assembly screw is a coarse-thread wood screw built for cabinet box construction, furniture assembly, and general woodworking panel joinery. The lubricated finish reduces driving friction, and the combination drive recess accepts either a #2 Phillips or a #2 square bit, so it works with the drivers already in the shop.
At 1-3/4", this screw reaches through a standard 3/4" panel and into a second member with enough thread engagement to hold the joint tight. That makes it a natural fit for cabinet box assembly — attaching sides to tops and bottoms, fastening back panels to the box frame, or securing interior partitions. It also works for furniture carcass work and drawer-box construction where a reliable flush-head fastener in a manageable length keeps the assembly clean on the inside face.
The sharp point self-starts in softwood, plywood, and most wood composite panels without a pilot hole in many applications. For hardwood components or edge-grain installation, a pilot hole will improve results and reduce splitting risk.
The lubricated coating is applied to the thread and shank so the screw moves into the material with less resistance than an uncoated fastener of the same size. In a production environment where the same motion repeats hundreds of times across a shift, lower driving torque reduces fatigue on the operator and wear on the driver. The combination recess — accepting either a #2 Phillips or a #2 square bit — means the screw is compatible with whatever driver is closest at hand, whether that is a Phillips-only setup or a square-drive bit preferred in many cabinet shops.
The flat head requires a pre-drilled countersink to sit fully flush. On plywood or MDF interior faces, a countersink bit run ahead of the screw delivers a clean, flat result at the surface.
A box of 4,000 is sized for shops that move through fasteners at volume — production cabinet lines, modular furniture manufacturing, and millwork operations where downtime from running out of screws has a real cost. The #8 gauge and 1-3/4" length cover the most common panel-joinery scenario in cabinet work, so this box is often the one that gets reordered as a standard stock item rather than a special order. Homebuilders and remodelers installing site-built cabinetry will also find the combination drive useful when the tool situation on site is less controlled than in the shop.
Yes. The combination recess accepts both a #2 Phillips and a #2 square bit, so either driver type engages the head without a separate screw.
Yes. A flat head seats flush only in a matching countersink. Running a countersink bit before driving the screw gives you a clean, flush result on the face.
The sharp point self-starts in many materials, but a pilot hole is recommended in hardwood to reduce splitting risk and keep the screw tracking straight.
The lubricant reduces the torque needed to drive the screw. It is applied to the thread and shank, not just the tip, so it works throughout the full drive depth.
This screw carries a lubricated finish, not an exterior corrosion-resistant coating. It is intended for dry, indoor woodworking and cabinet assembly applications.
When the job calls for a 1-3/4" flat head screw that drives fast, seats flush, and works with the bits already in rotation, this Würth assembly screw delivers that without complications — and 4,000 per box means the supply keeps pace with the work.
