The Würth #8 x 1-3/4" flat head assembly screw is a coarse-thread fastener built for joining cabinet panels, case components, and wood-based sheet goods where a flush-seated head and fast, clean driving matter. The 1-3/4" length is a practical fit for single-layer 3/4" panel work with meaningful thread engagement in the receiving piece.
At 1-3/4", this screw threads through one layer of 3/4" stock and bites approximately an inch into the receiving piece — enough engagement for solid panel-to-panel connections in cabinet carcass assembly, shelf dadoes, and back panel attachment. It also works well for securing drawer box components and attaching interior cabinet blocking where a shorter screw would leave too little thread in the secondary piece. Cabinet shops building face-frame boxes from 3/4" plywood or MDF will find this length practical as an everyday carcass fastener.
The flat head seats flush or slightly below the surface in most wood-based materials, and the underhead nibs do the countersinking work as the screw is driven — no separate countersink bit required in typical cabinet panels. The black finish reduces the visual impact of an exposed fastener head inside dark-finished cabinets, painted interiors, or melamine-lined boxes. This is an indoor fastener; the black coating is a surface treatment, not a corrosion system rated for wet or exterior exposure.
Cabinet shops running production builds keep this box on the bench for carcass assembly and interior component fastening. Finish carpenters and installers pull from it when driving screws into cabinet interiors where a black head blends better than a bright zinc one. The 1,000-piece count supports steady volume without the overhead of tracking smaller packs mid-project. The #2 Phillips drive means anyone with a standard driver bit can run this screw without switching kits.
In most wood and cabinet panel materials, no. The nibs under the flat head mill a countersink as the screw seats. In very hard substrates or finished laminates, a pilot may improve the result, but a separate countersink step is generally not needed.
The extended fluted tip clears wood fibers and chips ahead of the thread, which reduces driving torque and lowers the chance of splitting near edges or in denser panel materials. It is especially useful when driving repeatedly through production runs without letting the bit dwell.
For dry interior use — cabinet boxes, painted interiors, and melamine-lined cases — yes. The coating is not rated for exterior exposure or high-humidity environments, so keep this screw on indoor work.
Yes. The coarse thread grips well in MDF, particleboard, and plywood. In low-density particleboard, driving to full seating depth without over-driving gives the best pull-out performance.
A #2 Phillips bit. That is the standard bit most shops already run in their drivers, so no special tooling is required.
When the job calls for a screw that seats flush, blends into dark cabinet interiors, and drives cleanly through 3/4" panels without fuss, the Würth #8 x 1-3/4" assembly screw handles it straight from the box — no extra bits, no separate countersinking, and 1,000 per box to keep production moving.
