This Würth #8 x 1-1/2" flat head assembly screw is a coarse-thread, Phillips-drive fastener built for wood panel assembly, cabinet box construction, and general shop joinery. The 1-1/2" length gives solid thread engagement through standard 3/4" material into an adjoining panel or backing, making it a reliable choice when you need a flush-seated screw that disappears into the work.
At 1-1/2", this screw threads through a 3/4" face panel and buries fully into the adjoining member, pulling the joint tight without blowing through the back face. That makes it well suited for cabinet box assembly, back panel attachment, drawer box construction, shelf pin backing, and interior carcass joinery where a countersunk, flush finish matters. It also handles light face-frame-to-box attachment in softwood and pine where the screw enters at an angle and the length keeps it well inside the material. In shop settings, it covers a wide range of everyday joinery tasks where a #8 coarse-thread is the right call and nothing longer is needed.
The black finish keeps screw heads from standing out inside painted or dark-laminate cabinet interiors. It is an interior finish suited to dry shop and installed cabinet environments. For outdoor work or applications with moisture exposure, choose a screw with a rated exterior coating. The #8 gauge gives a balance of shank strength and head size that works without oversizing the countersink in typical 3/4" cabinet material.
Cabinet shops running production benefit most from the 1,000-count box: the length and gauge cover a broad share of carcass assembly tasks, so one box serves multiple operations without switching screws. Installers trimming out a kitchen or bath keep a handful of these on hand for quick repairs, pocket patches, and last-minute adjustments to cabinet backs and shelving. The Phillips drive is the right call when the job uses mixed tooling and a square or star driver is not always within reach.
It depends on angle of entry. Driving straight through one 3/4" panel into an adjoining panel works well at this length. For pocket-hole joinery through two 3/4" pieces, a 1-1/4" screw is more typical. At 1-1/2" you get extra thread engagement, which suits back panel attachment and carcass box joints where the screw enters at or near perpendicular.
The sharp point self-starts in softwood, pine, and most sheet goods without a pilot hole. In dense hardwood or close to an edge, a pilot hole reduces splitting risk and keeps the screw tracking straight.
Yes. A flat head needs a matching countersink to sit flush. In softer materials the head may self-countersink under driving pressure, but a dedicated countersink bit gives a cleaner, more consistent result in hardwood, MDF, and melamine.
Yes, for dry indoor environments. The black finish is an interior coating. It keeps fastener heads visually inconspicuous inside dark or painted cabinet boxes, which is the primary reason to reach for it over a zinc-plated alternative in cabinetry.
A #2 Phillips bit. That is the standard size for #8 wood and assembly screws and fits the vast majority of drill/driver sets already in use.
When the assembly line is moving and you need a flush-seated #8 that covers the most common panel-thickness combinations without switching lengths mid-run, this is the screw to keep on the shelf.
