The Würth #8 x 3" washer head installation screw is built for cabinet installation and general interior woodworking where extra reach is needed. At 3 inches, it drives through face frames, panel stacks, and mounting substrates where shorter screws fall short. The washer head distributes clamping load across a wide bearing surface, and the combination Phillips/square drive accepts whichever bit is already in the gun.
Most installation work lands in the 1 to 2 inch range, but certain tasks demand more penetration depth. Securing a cabinet to a wall through a finished panel and into framing, running a screw through a face frame and into a thick stile stack, fastening cabinet components to blocking or a thick nailer, attaching a base cabinet through toe-kick material into a subfloor cleat — these are situations where a 3 inch screw does the job a shorter one cannot finish. The washer head keeps the fastener from sinking too deep into softer wood or pulling through panel faces under load.
The black finish on this screw is practical, not just cosmetic. Cabinet interiors, dark melamine boxes, and finished plywood panels all benefit from a fastener head that does not stand out visually once the door closes. The washer head adds to that by sitting flat and broad against the surface rather than countersinking, which also means no countersink prep is needed before driving. Coarse thread and sharp point construction keep this screw suited to interior wood and wood-composite substrates — it is not rated for exterior or pressure-treated applications.
Cabinet installers working on site are the natural fit here. When the wall substrate is unknown, when cabinets are going into a finished space over existing material, or when the run calls for driving through multiple layers to hit solid backing, the 3 inch length provides margin that a 2 or 2-1/2 inch screw does not. Production shops assembling heavy-duty carcasses with thick gussets or reinforced corner blocks also find this length useful. The 1500-count box suits crews running volume installs where replenishing a smaller package mid-job slows the pace.
No. The combination recess accepts a standard #2 Phillips bit or a #2 square bit. Use whichever is already loaded in your driver. The square recess is designed to hold the screw on a correctly sized bit for one-handed placement, though actual retention depends on bit fit.
No. The washer head is a flat bearing head that sits on the surface of the material rather than sinking into it. If a flush or sub-flush finish is required, a flat countersunk head screw is the better choice.
This screw carries a black finish suited for dry interior work. It is not rated for pressure-treated lumber or outdoor exposure. For exterior and treated-lumber applications, choose a screw with a coating rated for those conditions.
The sharp point self-starts in most wood and wood-composite substrates without a pilot hole. In very dense hardwood or when driving close to an edge, a pilot hole reduces the risk of splitting.
A full cabinet installation job can consume these quickly when every cabinet run requires multiple screws per unit into wall framing. The 1500-count box reduces the chance of running short mid-install and avoids the cost premium of smaller packs on a volume job.
When the substrate is thick, the panel stack is deep, or the framing is set back further than a standard installation screw can bridge, the 3 inch Würth washer head installation screw gives cabinet installers and production shops the penetration depth to complete the connection cleanly and keep the job moving.
