This Würth #8 x 2-1/2-inch washer head installation screw is sized for cabinet box construction, shelf attachment, and other wood assembly tasks where the fastener must drive through combined stock thicknesses with confidence. A sharp point, coarse thread, and Phillips/square combination drive give it broad compatibility with the bits already on the bench or in the driver.
Cabinet box construction regularly calls for a screw long enough to pass through one panel face and bite deep into a second member. At 2-1/2 inches, this screw handles those layered connections: attaching a bottom panel through a side, securing a back nailer, or fastening a cabinet to wall blocking. It also works well for pulling apart a stack of finish panels or fastening thicker solid-wood components in millwork and casework. The length is the deciding factor for these jobs, and the coarse thread delivers the pull-out resistance that panel-to-panel joints need.
The round washer head sits flat against the panel surface and distributes clamping force over a larger area than a standard flat or pan head. That matters in plywood and particleboard, where a smaller head can pull inward under load. The combination drive recess accepts both a #2 Phillips and a #2 square bit, so the screw runs with whichever driver is already loaded. Square drive holds better under torque and is the preferred choice when driving volume is high. The zinc finish is suited to dry, indoor environments: cabinet shops, interior installations, and enclosed millwork.
The 2,000-piece box is sized for shops and crews that go through installation screws steadily. Cabinet builders assembling box runs, installers hanging upper and lower cabinet banks, and millwork teams fastening built-ins all benefit from having a full-case quantity on hand rather than refilling smaller containers mid-job. The combination drive also means a single screw works with both the square-drive bits common in shop production and the Phillips bits contractors typically carry to the job site.
The washer head's wide, flat bearing surface spreads the clamping load over more material, which reduces the chance of the head pulling through plywood or particleboard edges under load. A flat head requires a countersink and a pan head has a smaller footprint than a washer head at the same gauge.
The combination recess accepts both a #2 Phillips and a #2 square bit. Either will drive the screw. Square drive holds better under high torque, especially in repetitive production driving, because the bit engages with less tendency to slip out of the recess.
Yes. The sharp point self-starts in softwood, plywood, and most engineered panel materials without a pilot hole. In very dense hardwood or near panel edges, a pilot hole helps prevent splitting.
Zinc plating provides standard corrosion protection for dry, indoor environments. It is appropriate for cabinet box interiors, interior millwork, and enclosed built-ins where the fastener stays in a controlled climate.
No. This washer head installation screw does not have nibs. The flat washer head sits directly against the material surface.
When the assembly calls for a screw with enough length to lock two cabinet components together firmly, the Würth #8 x 2-1/2-inch washer head installation screw delivers the length, bearing surface, and drive flexibility to keep the work moving.
