The Würth #8 x 3" flat head assembly screw is built for cabinet and casework joints where a longer fastener is needed to pull panels, frames, and structural components tight. The combination Phillips/square drive, turbo thread, lubricated finish, and flat head with milling nibs work together to keep driving smooth and consistent from the first screw to the last in a full production box.
Three inches of length opens up fastening situations that shorter screws cannot address cleanly. Joining a face frame to a cabinet box through thicker substrate, connecting two panels where combined stock depth exceeds an inch and a half, pulling adjacent cabinet units together through stiles, or running screws through a base plate and into structural backing — these are the jobs this length is sized for. The turbo thread design bites quickly and reduces the rotation count needed to fully seat the screw, which matters when a single assembly run means hundreds of fasteners. The sharp point self-starts in softwood, hardwood, MDF, and particleboard without requiring a separate pilot step in most installations.
The lubricated finish on this screw is dry to the touch and applied to the threads and shank to lower installation friction without leaving residue on finished surfaces or interfering with glue lines. That friction reduction extends bit life noticeably over a full box of 1500. The flat head carries milling nibs on its underside that cut a clean countersink into the surface material as the screw seats, eliminating a separate countersink step in many hardwood and laminate applications and leaving the head flush with the panel face. The combination drive recess accepts a #2 Phillips or a #2 square bit — two of the most common bits already on a cabinet shop's drivers — so there is no need to change bits based on what is loaded.
Cabinet shops assembling boxes and attaching face frames will use the most of these. The 3-inch length also suits millwork installers scribing base cabinet runs to walls and joining adjacent units, finish carpenters fastening thick built-up trim assemblies, and production woodworking operations where a single screw size needs to cover a range of thick-stock connections. The 1500-piece box supports ongoing production without constant restocking interruptions.
The combination recess accepts a #2 Phillips bit or a #2 square bit. Either will drive the screw fully; the square recess is designed to hold the screw on a correctly sized bit for easier placement in tight spaces.
Yes. The turbo thread and sharp point are suited to softwood, hardwood, MDF, and particleboard. In very dense hardwood, a pilot hole may reduce splitting risk, particularly near edges.
The lubricated finish on these screws is a dry-applied coating on the threads and shank. Avoid driving screws directly into a wet glue line, but incidental proximity to a cured or dry joint is generally not a concern.
The underhead nibs mill a countersink into the surface material as the screw seats, allowing the flat head to sit flush without a separate countersink drill operation in most wood and panel substrates.
This screw carries a lubricated finish on steel and is intended for interior woodworking and cabinet assembly applications. It is not rated for exterior exposure or wet environments.
The Würth #8 x 3" combo drive assembly screw delivers consistent driving behavior from the first screw to the 1500th, making it a dependable choice for any shop where thick-stock joinery and high-volume cabinet assembly are part of the daily workload.
