The Würth #8 x 1-3/4" washer head assembly screw is a production-ready fastener for cabinet carcass assembly, panel joinery, and wood-to-wood connections where a 1-3/4-inch length lands in the sweet spot between shallow hardware-mounting screws and longer structural fasteners. The washer head, turbo thread, lubricated finish, and combo drive work together to keep driving fast and consistent across a full box of 1000.
At 1-3/4 inches, this screw has enough shank to anchor firmly through typical 3/4-inch cabinet panels and well into a second member, without breaking through the back face of thinner assemblies. That makes it a natural fit for face-frame-to-box attachment, drawer-box corner assembly, and shelf-pin-hole backing strips where a shorter screw would leave marginal bite and a longer one would risk exit on the opposite face. It also handles panel-to-panel joinery in frameless carcasses and secondary wood-to-wood connections inside a cabinet run where a consistent fastener across the whole job saves time at the tool belt.
The washer head seats broadly against the panel face, and the underhead nibs mill into the surface as the screw is driven, pulling the head flush without requiring a separate countersink step in most wood-based substrates. The turbo thread's wide pitch clears material quickly, which matters when a shop is driving hundreds of screws per shift. The lubricated finish is dry to the touch and applied to the thread and shank surfaces; it reduces the friction load on the driver and on the material around the bore, which helps prevent heat buildup and surface burnishing in laminated or melamine-faced panels. The combo drive recess accepts both a #2 Phillips and a #2 square bit. The square recess is designed to hold the screw on a correctly sized bit for more controlled placement in tight cabinet interiors.
Cabinet manufacturers running frameless or face-frame lines will recognize this length as a workhorse size — long enough to handle most panel-to-panel and frame-to-box joints in 3/4-inch stock, compact enough to avoid interference problems in assembled runs. Finish installers hanging pre-built cabinet boxes benefit from the same versatility: the combo drive means a Phillips or square bit works without stopping to switch, and the lubricated turbo thread drives without bogging down even in denser engineered panels. The 1000-piece count matches the volume pace of a full kitchen or bath install and suits the replenishment rhythm of a busy production floor.
The sharp point self-starts in particleboard and most wood-based panels in most conditions. In dense or edge-grain situations, a pilot hole reduces the risk of surface chipping around the entry point. The lubricated finish helps the screw seat cleanly once threading begins.
The 1-3/4-inch length gives roughly an inch of thread engagement beyond a 3/4-inch near-side panel, which is meaningful grip without risking exit on a 3/4-inch back panel of a shallower assembly. If the receiving member is thicker, step up to 2 inches. If working in thinner stock or close to an edge, 1-1/2 inches may be safer.
Either bit works in the combo recess. A #2 Phillips or a #2 square driver both engage the same recess. Most installers reach for whichever bit is already in the driver, which is exactly what the combo drive is designed for.
The lubricant reduces friction between the thread faces and the surrounding material as the screw drives. In practice, that means less torque required to seat the screw, less heat at the bore, and reduced surface stress on laminates and faced panels near the fastener.
The washer head sits on the surface rather than countersinking flush, so it is best suited for interior structural connections, cabinet backs, drawer boxes, and anywhere the fastener face is not a finish surface. For exposed faces where a flush or sub-flush head is needed, a flat head countersunk screw is the better choice.
When the job calls for a reliable mid-length assembly screw that drives fast, seats cleanly, and works with the bits already on the tool, the Würth #8 x 1-3/4" washer head assembly screw covers it — one size, one box of 1000, ready to run.
