This Würth #8 x 1-3/4" flat head assembly screw pairs a Type 17 Auger point with a coarse thread, milling nibs, and a #2 square drive to deliver fast, clean fastening in cabinet boxes, carcass panels, and general wood assembly. The 1-3/4" length spans common material combinations — two layers of 3/4" stock with room to pull the joint tight — making it a practical choice for production shops running consistent panel-to-panel work.
At 1-3/4", this screw is well matched to joints where two panels of 3/4" stock meet and you want the fastener to penetrate fully into the receiving piece without blowing through. That span covers cabinet box assembly — side panels to top and bottom, back panel attachment in thicker stock, and similar carcass joints. It also works in frame-and-panel build-up where you're running through one layer and threading into another. The coarse thread pulls quickly in plywood and solid wood, and the Type 17 Auger point starts cleanly without requiring a pilot hole in most softwood and mid-density hardwood applications.
The #2 square drive recess gives better bit engagement than a comparable Phillips on a power driver, which matters in repetitive production runs where cam-out slows the line. The flat head profile with milling nibs handles its own countersinking in wood-based substrates, seating flush without leaving a raised ring or requiring a separate operation. The black finish keeps fastener heads visually quiet in dark cabinet interiors, painted assemblies, and any application where a silver or zinc head would stand out. This is an indoor assembly screw — the black finish is functional for appearance, not rated for exterior or high-moisture environments.
Cabinet shops running face-frame boxes, frameless carcasses, or built-in millwork components go through flat head assembly screws at volume, and the 4,800-count box reflects that reality. The combination of square drive, Type 17 Auger point, and milling nibs suits shops that want consistent seating across a full production run without changing bits or adding countersink operations. Contractors assembling site-built cabinetry, closet systems, or furniture components will find the 1-3/4" length covers most standard panel-thickness combinations without special sizing.
In most softwoods and mid-density hardwoods, the extended auger flute clears material as it drives and reduces the torque and splitting risk enough to skip a pilot hole. In very dense hardwoods or close to an edge, a pilot hole is still good practice to prevent splitting.
Yes. The nibs mill a countersink as the head seats in plywood, MDF, and particleboard, as well as in solid wood. Results are cleanest when you drive at consistent speed rather than hammering the head in with an impact driver at full power.
The black finish blends well under dark stains, black paint, and in unfinished cabinet interiors where a low-visibility fastener is preferred. It is not a corrosion-rated finish for exterior or wet applications.
This screw uses a #2 square drive. A correctly sized #2 Robertson bit seats firmly in the recess for controlled driving. A worn or undersized bit will reduce engagement and increase the chance of slipping.
It is a common choice for that joint. The screw passes through the first panel and threads into the second, with enough penetration to pull the joint tight. If the receiving piece is thinner than 3/4", verify that penetration depth is sufficient for the load.
When the job calls for a clean-seating, fast-driving flat head assembly screw in a length that covers standard panel-to-panel work, this Würth #8 x 1-3/4" delivers it at the volume a working shop actually needs.
