The Würth #8 x 1-3/4" flat head assembly screw is a coarse-thread, combo-drive fastener designed for wood panel assembly, cabinet carcass construction, and general woodworking. The 1-3/4" length gives it solid thread engagement in 3/4" material while leaving enough shank to pull joints tight — a practical fit for panel-to-panel and panel-to-solid-wood connections where a shorter screw would come up short.
The 1-3/4" length is a reliable choice when joining two layers of 3/4" sheet material — common in cabinet box assembly, nailer strips, and panel-to-cleat connections. It penetrates deep enough into the receiving piece to hold under load, without punching through thinner back panels or bottoms. It also works well through 3/4" material into solid-wood blocking or mounting rails, where consistent thread engagement matters more than raw length. Production shops building frameless or face-frame cabinets will find this length handles the majority of carcass fastening without needing to switch to a longer screw.
The flat head countersinks flush with the panel surface, keeping the interior of a cabinet box clean and snag-free. Milling nibs on the underside of the head cut their own seat as the screw drives in many wood-based substrates, reducing the need to run a countersink bit before driving. The black finish sits quietly against dark interiors, painted panels, and melamine surfaces — a small detail that matters when cabinet boxes are visible or left unlined. The finish is suited for dry interior conditions.
Cabinet shops running production lines use this screw to knock out carcass assembly efficiently: the combo drive means no bit swap when the square driver is busy at another station and a Phillips is closer. Finish carpenters installing pre-built cabinet boxes on site carry this length for attaching nailers, backing cleats, and mounting rails to the box with a single pass. The 1000-piece box fits both scenarios — enough volume to run through a full cabinet set or a multi-room installation without tracking down a resupply mid-job.
When fastening through one layer of 3/4" panel into a second, 1-3/4" gives roughly 1" of thread engagement in the receiving piece — enough to hold the joint firmly without punching through typical panel thicknesses. It is a practical middle-ground length for cabinet carcass work and panel-to-cleat connections.
The Type 17 Auger Point has an extended fluted tip that actively clears wood fibers and chips as the screw drives, rather than simply displacing them. This lowers the torque needed to seat the screw and reduces splitting, especially in denser materials like hardwood plywood or thick MDF.
Yes. The combo recess accepts both a #2 Phillips and a #2 square bit. Either will drive the screw; the square recess is designed to hold the screw on a correctly sized bit for easier one-handed placement.
Yes. The coarse thread is well suited for MDF, particleboard, and melamine-faced panels. The Type 17 Auger Point and milling nibs also help reduce surface blow-out around the entry hole in these materials.
No. This screw is intended for dry interior applications. For exterior or high-moisture environments, choose a screw with a corrosion-resistant coating rated for that exposure.
At 1000 per box, this screw is sized for shops and installers who go through fasteners in volume — one box handles a substantial run of cabinet carcasses without the stop-and-reorder that smaller packs require.
