This Würth #10 x 3-inch washer head installation screw is built for cabinet and casework assembly where you need full engagement through thicker panels, built-up layers, or stacked material. The washer head spreads clamping load across a wide bearing surface, the coarse thread bites into solid wood and sheet goods, and the Phillips/square combination recess lets you drive with whichever bit is already in your tool.
Most installation screws in this family are sized for single-panel or face-frame attachment, but the 3-inch length is the right choice when the fastening path runs through more material. Attaching a cabinet back panel through a 3/4-inch side wall and into blocking, securing a filler strip against a cabinet run with stacked build-out, or drawing a finished end panel tight against a face-frame rail are all situations where shorter screws come up short. The extra length keeps threads working in sound material rather than running out in air or end grain.
The washer head seats against the surface without countersinking, making it the right choice when a flush countersunk finish is not needed and pull-through resistance matters more. In particleboard and MDF, where edge pull-out is a real concern, the wide bearing surface of the washer head holds. The coarse thread provides good withdrawal resistance in the softwoods, plywood, and engineered panels that make up most cabinet boxes and site-built assemblies. The zinc finish is calibrated for interior work, which covers nearly every installation this screw is sized for.
Cabinet installers who build out walls before hanging a run, trim carpenters who add blocking or nailers through finished panels, and production shops that secure cabinet backs or panel edges in thick assemblies all find a use for the 3-inch length in this family. The 1000-piece box suits shops and crews that burn through installation screws on active projects, and the combination drive means the screw works in any tool rotation without hunting for a specific bit.
Use it when the fastening path passes through more than 3/4 inch of material before reaching the substrate you are threading into, such as a build-out layer plus a panel, or a back panel attachment into a 1-1/2-inch wall cleat.
No. The washer head is designed to bear flat against the surface, not seat in a countersink. It is the right head style when a proud bearing surface is acceptable and pull-through resistance is the priority.
Yes. The combination recess accepts a #2 Phillips or a #2 square bit. Either works in the same recess, so you do not need to switch bits when changing between driver types on the job.
No. The zinc finish is rated for dry interior applications. For outdoor or high-moisture environments, choose a screw with a heavier corrosion-resistant coating.
In most wood-based substrates, the sharp point self-starts without a pilot hole. In very dense hardwood or when driving close to an edge, a pilot hole reduces the risk of splitting.
When the application calls for deep reach through layered material, the 3-inch washer head installation screw delivers the thread engagement and bearing surface that shorter screws in this family cannot, packed 1000 to the box for shops and installers who need it in volume.
