The Würth #8 x 1-3/4" flat head assembly screw is a coarse-thread, zinc-plated fastener built for wood-to-wood assembly in cabinetry, furniture, and millwork. The 1-3/4" length is a practical match for joining 3/4" panels to solid-wood components or stacking two 3/4" sheets, putting full thread engagement to work without over-penetrating the substrate.
At 1-3/4", this screw reaches through one layer of 3/4" material and buries the full threaded section into the second member, which is exactly what a solid cabinet box joint or a rail-to-panel connection needs. It is long enough to anchor securely through applied face material into a backing board, yet short enough to avoid break-through on thinner assemblies. Cabinet shops building face-frame boxes, joining drawer rail supports, or fastening nailer strips inside a carcass will find this length covers a wide range of routine tasks without changing screws mid-run. It also works for attaching wood cleats, mounting interior bracing, and general wood-to-wood joinery where a coarse-thread screw and a flat flush head are the right combination.
The Type 17 Auger Point features an extended flute that acts as a chip-clearing channel as the screw is driven. In softwood and plywood, this reduces the torque required to reach full depth and lowers the chance of splitting at the entry point. The flat head carries underhead nibs that cut into the surface material and seat the head cleanly flush in wood, MDF, and many laminated panels — useful when a visible countersink would need to be filled or when driving speed matters. The zinc finish is the right call for dry interior work. It is not rated for exterior exposure or direct contact with pressure-treated lumber.
Cabinet manufacturers running steady daily output are the natural home for a 4,800-piece box. The combination of a standard #2 Phillips drive, a self-starting Type 17 point, and a self-countersinking flat head with nibs suits shops that want reliable, consistent results from an assembly screw without extra process steps. It is equally useful for millwork shops fastening built-up assemblies, furniture manufacturers joining solid-wood parts to sheet-good components, and finish carpenters who need a flat-head wood screw they can drive flush without stopping to countersink each hole.
At 1-3/4", the screw passes through the near-side panel and puts the full threaded section into the second member. That gives the coarse thread maximum material to grip without the tip breaking through the back face of standard 3/4" stock.
In most wood, softwood plywood, and MDF, the nibs mill a clean countersink as the head seats, so a separate countersink step is usually not needed. In very hard or thin stock, a shallow countersink pilot can help the head seat cleanly.
The coarse thread and Type 17 Auger Point work well in softwood, plywood, and engineered sheet goods. For dense hardwoods like maple or oak where splitting is a concern, a fine-thread screw is the better choice for face-frame joinery in those species.
The zinc finish is suited for dry indoor applications only. It is not rated for exterior exposure or contact with ACQ pressure-treated lumber. For outdoor or treated-lumber work, choose a screw with a corrosion-resistant coating rated for those conditions.
A standard #2 Phillips bit fits this screw. That is one of the most common bits in shops and on job sites, so no special tooling is required.
When the job calls for a flat-flush, self-countersinking wood screw at a length that serves a wide range of panel and solid-wood joints, the Würth #8 x 1-3/4" assembly screw delivers consistent results from the first drive to the last screw in the box.
