The Würth #8 x 1-1/2" flat head assembly screw is a high-volume fastener built for production cabinet shops and woodworking operations where consistent, flush-seated results matter. The 1-1/2 inch length is the go-to dimension for joining 3/4-inch panels, cabinet carcasses, and face-frame components where you need full thread engagement without over-penetrating the back face.
At 1-1/2 inches, this screw lands squarely in the range cabinet builders rely on most. Driving into a 3/4-inch melamine or plywood panel, the screw passes through the near face and threads deep enough into the substrate for solid pull-out resistance without the tip emerging on the show side. That same length handles drawer box construction, shelf pin rail attachment, and back-panel fastening where controlling penetration depth is part of producing a clean interior. For shops running high volumes of standard cabinet carcasses, keeping 7000 of this length on hand means the right screw is always within reach for the most common joint in the box.
The black finish is applied over the full screw body, making the head less visible against dark cabinet interiors, painted box sides, and melamine panels in charcoal or espresso tones. Beneath the head, the underhead nibs relieve wood fibers as the screw seats, helping the flat head countersink flush without tearing laminate faces or requiring a separate drill pass. The Type 17 Auger Point extends the standard T17 flute geometry into a longer, more aggressive chip-clearing profile suited for the repeated, fast-paced driving that characterizes production assembly. Coarse thread and carbon steel construction round out a screw designed to perform consistently across shift after shift.
A 7000-piece box is a production quantity. This screw is the right fit for cabinet manufacturers, millwork operations, and custom shops running steady output where interrupting a run to reorder is not an option. The #2 square drive pairs with the bits already on most shop drivers and reduces cam-out during high-cycle driving. The coarse thread handles the softwood, plywood, and engineered panel substrates that make up the bulk of cabinet construction. This is an indoor screw suited to dry shop environments and finished interior cabinet work.
The screw needs enough thread past the near-face to grip firmly in the receiving panel. At 1-1/2 inches, a #8 flat head screw clears the 3/4-inch face panel and drives a full 3/4 inch into the substrate, providing solid pull-out resistance without the tip breaking through on a single-thickness panel back.
The Type 17 Auger Point has an extended flute that clears wood chips away from the tip as the screw is driven. This reduces the torque needed to seat the screw and lowers the risk of splitting, particularly in panels where repeated driving close to an edge is common.
In most wood-based substrates including plywood, MDF, and particleboard, the underhead nibs mill enough material as the screw seats to let the flat head sit flush without a separate countersink step. In laminated panels, results depend on the surface hardness and laminate type.
This screw carries a coarse thread, which is the right choice for softwood, plywood, MDF, and particleboard. Coarse thread provides less holding power in dense hardwoods like maple and oak compared to fine thread, so for hardwood face-frame joinery a fine-thread face-frame screw is the better fit.
The square recess is designed to hold the screw on a correctly sized bit for one-handed placement. That hold depends on using a properly fitting #2 square bit; a worn or off-spec bit will not provide the same retention.
No. The black finish on this screw is suitable for dry interior applications. It is not rated for exterior exposure, high-humidity environments, or contact with pressure-treated lumber.
When the job is assembling 3/4-inch cabinet carcasses, drawer boxes, or shelf panels in volume, the Würth #8 x 1-1/2" flat head assembly screw delivers the length, point, and thread combination that keeps the line moving with clean, flush-seated results every time.
