The Würth #8 x 1-3/4 inch flat head assembly screw is a coarse-thread wood screw with a square drive, Type 17 Auger point, milling nibs, and zinc finish. At 1-3/4 inches, it drives through a single layer of 3/4-inch material and seats cleanly without a separate countersink step, making it a reliable everyday screw for cabinet box assembly, carcass construction, and general woodworking.
The 1-3/4 inch length is the practical reach for single-panel fastening in 3/4-inch cabinet material. It covers face-panel attachment to a carcass side, back-panel ledger strips, shelf-pin rail installation, and drawer-box corner joints where the fastener needs to clear the near face and bite solidly into the second member without punching through a shallow substrate. Cabinet shops running production on 3/4-inch sheet goods will find the length consistently useful across a broad range of joinery positions without requiring a longer screw that risks breakthrough on thin stock.
The Type 17 Auger point carries an extended flute that evacuates chips ahead of the thread, which matters most in dense hardwood and in situations where the screw must start close to an edge. The flat head's milling nibs relieve wood fibers as the head seats, producing a flush countersink in the surface without mushrooming. The #2 square drive holds up well under the torque of a production driver and is less prone to cam-out than a Phillips recess, which helps keep work moving when driving hundreds of screws in a session. The square recess is designed to hold the screw on a correctly sized bit for one-handed placement, though that result depends on using a properly fitting bit.
This SKU ships 4,800 screws to the box. That volume suits cabinet shops and millwork operations where the 1-3/4 inch length is a go-to size on the production floor. Having a deep stock of a single screw reduces bin changes and keeps assembly stations stocked through a full production run. The zinc finish is appropriate for indoor cabinet and furniture work in dry environments.
It gives enough thread engagement beyond a single 3/4-inch panel to hold firmly in the second member while staying short enough to avoid breakthrough on standard sheet-good thickness. That makes it a reliable choice for attaching panels, ledger strips, and drawer-box corners in typical 3/4-inch cabinet construction.
The milling nibs are designed to cut their own countersink in solid wood and most engineered panels as the head seats, so a separate countersink step is often unnecessary. Results vary with material density and surface finish, so test in your specific substrate if a perfectly flush result is critical.
The extended flute on the Type 17 Auger clears chips as the screw starts, which reduces driving torque and lowers the risk of splitting near edges or end grain. A standard sharp point displaces material without chip clearance, which can build pressure and crack the workpiece in harder wood.
This screw is finished for dry indoor applications. For outdoor work or contact with pressure-treated lumber, a screw with a corrosion-resistant coating rated for exterior exposure is the right choice.
The drive size is #2 square. A #2 Robertson or square bit is the correct fit. Using a correctly sized bit is important for reliable bit retention and clean torque transfer.
When 3/4-inch panel assembly is the job and production volume demands a deep supply, this Würth #8 x 1-3/4 inch square drive flat head screw delivers the length, head geometry, and pack size to keep the line moving.
