The Würth #8 x 2-1/2" Washer Head Assembly Screw is a lubricated, turbo-thread screw built for cabinet assembly, furniture construction, and general woodworking where the joint calls for deeper penetration into thicker material. The washer head with nibs seats flush and distributes clamping load broadly, while the combo drive keeps things moving whether a Phillips or square bit is in the driver.
At 2-1/2", this screw reaches through thicker assemblies that shorter lengths cannot reliably pin. That puts it at home fastening face-frame components to deeper cabinet boxes, joining furniture sub-assemblies built from doubled panels, attaching cabinet nailers and stretchers, and securing back panels or structural cleats where the screw needs to travel through one layer and bite well into a second. The 2-1/2" length also works well for attaching shelf standards, drawer guide blocking, and interior cabinet components where the combined stock runs in the 1-1/2" to 2" range and a short screw would leave marginal thread engagement in the receiving piece.
The broad washer head spreads clamping force over a larger footprint than a pan or flat head, which matters when fastening into particleboard or MDF edges where pull-through resistance is limited by the panel's fiber density. The milling nibs on the underside of the head relieve wood fibers as the head seats, helping it pull down cleanly without tearing laminate faces or leaving a raised ring around the fastener. The turbo thread's wide pitch moves material efficiently and reduces the number of driver rotations to full depth, which adds up across a production run. The lubricated finish keeps friction low from the first revolution to the last, and the combo recess means the crew does not stop to swap bits when one driver is already loaded with a square and another has a Phillips.
Cabinet shops building boxes from sheet goods, furniture manufacturers joining sub-assemblies, and millwork installers fastening interior components are the primary audience for this screw. The combination of a washer head, turbo thread, lubricated finish, and 2000-piece pack is designed for environments where the fastener has to perform consistently on the hundredth screw the same as the first, and where stopping to pre-drill or swap bits costs real time. The sharp point handles softwood, plywood, particleboard, and MDF without a pilot in most conditions. For dense hardwoods or edge-distance situations where splitting is a concern, a pilot hole is a straightforward way to protect the material.
The washer head's wider bearing surface distributes clamping load over more material, which is especially useful in particleboard and MDF where a smaller head can pull through under load. The milling nibs also help the head seat cleanly in laminates without a separate countersink pass.
Turbo thread uses a wider, more aggressive pitch that reduces the driving torque needed and moves material faster per revolution. That means fewer rotations to full depth and less heat at the drive recess during production runs.
Yes. The same recess accepts a #2 Phillips or a #2 square bit. You get the cam-out resistance of the square drive when using a correctly sized square bit, or the widespread availability of Phillips when that is what is loaded.
The sharp point self-starts in softwood, plywood, particleboard, and MDF without a pilot hole in most cases. In dense hardwood or when driving close to an edge, a pilot hole helps prevent splitting.
This screw carries a lubricated finish, not a corrosion-protective coating rated for exterior or wet environments. It is intended for indoor cabinet, furniture, and woodworking assembly.
When the job calls for a screw that drives fast, seats cleanly, and handles the material depth of thicker cabinet and furniture assemblies, the Würth #8 x 2-1/2" Washer Head Assembly Screw delivers that consistently across a 2000-piece box.
