The Würth #8 x 2-1/2" Washer Head Installation Screw is a coarse-thread, sharp-point fastener built for cabinet installation, furniture assembly, and general woodworking joinery where 2-1/2 inches of penetration is the right call. The wide washer head distributes clamping load cleanly, and the combination Phillips/square recess means the screw works with the driver bits already on the job.
Cabinet installation often calls for screws that can pull through a face frame and still bite deep into wall framing or a cabinet stile behind it. At 2-1/2 inches, this screw handles that reach. It is also the right length when fastening cabinet boxes together through doubled panel walls, securing stretcher rails, or driving through blocking into a substrate. Shorter screws lack the thread engagement; longer screws risk blowing through. This length is the working middle ground for those multi-layer installation scenarios.
The round washer head sits flat against the surface rather than countersinking into it, making it the natural choice anywhere a flush, non-recessed bearing surface is needed: cabinet-to-wall attachment, hanger strips, nailers, and panel joinery where the fastener is hidden behind the finished assembly. The combination Phillips/square recess is designed to accept a correctly sized bit from either drive family, which matters on a busy install where the crew may be running different drivers. The square recess is cut to hold the screw on a correctly sized bit for one-handed placement when positioning awkward panels or reaching into tight cabinet runs. The black finish keeps heads from drawing the eye in dark interiors.
A box of 2000 suits shops and installers who move through cabinets quickly and do not want to track multiple screw lengths across an install. The coarse thread performs in solid wood, plywood, MDF, and particleboard, so the same screw covers cabinet-to-wall fastening, box-to-box connection, and blocking attachment in a single job. The sharp point starts without pre-drilling in most installation substrates, keeping the work moving.
When fastening through a face frame into wall framing, or through two cabinet panels stacked together, 1-1/2 or 2 inch screws often lack the thread engagement needed to pull the joint tight. The 2-1/2 inch length bridges that gap, giving you enough penetration to seat the fastener securely in the backing material.
Yes. The washer head and 2-1/2 inch length make this a common choice for driving through a cabinet back or hanging rail into wall studs. The wide bearing surface of the washer head keeps the head from pulling into the panel.
The combination recess accepts a #2 Phillips or a #2 square bit. Using a correctly sized square bit allows the screw to stay on the bit for one-handed placement, which is useful when reaching into a cabinet box or holding a panel in position.
The coarse thread and sharp point work in MDF and particleboard, as well as solid wood and plywood. For edge-fastening in very low-density particleboard, a pilot hole helps prevent blowout near the edge.
The black finish is a functional coating that reduces the visual contrast between the screw head and dark cabinet interiors. It provides standard indoor corrosion resistance appropriate for dry installation environments.
When the job calls for a long installation screw that handles multi-layer fastening, stays on the bit, and disappears inside a dark cabinet, this Würth washer head screw in 2-1/2 inch is the straightforward choice, packed 2000 to the box so supply does not slow the work down.
