The Würth #8 x 1-3/8" Washer Head Assembly Screw is a lubricated, turbo-thread fastener designed for high-volume cabinet and furniture assembly. The 1-3/8 inch length is a practical match for joining 3/4-inch panels with a backing layer, attaching hardware blocking, or securing components where a shorter screw falls short and a longer one risks blowout. The washer head, combo drive, and lubricated finish are built to keep a production line moving.
At 1-3/8 inches, this screw is sized for assembly situations that fall between standard panel-to-panel lengths. It handles a 3/4-inch panel face paired with a secondary layer — a nailer strip, a backing panel, or a cleat — where a 1-1/4 inch screw would leave too little thread in the second piece and a 1-1/2 inch screw would push through. It also works for attaching drawer-box components, cabinet bottoms into dado grooves reinforced with a cleat, and light face-frame attachment to softwood or plywood boxes where a moderate thread depth is all that is needed. The washer head bears against a wide footprint rather than countersinking, so it is the right choice when flush countersinking is not the goal and bearing surface and pull-through resistance are.
The lubricated finish on this screw is a dry-to-the-touch coating applied to the thread and shank surfaces. It does not change the appearance or create mess on finished panels, but it measurably lowers the torque required to drive the screw — which matters across thousands of fasteners in a single production run. The turbo thread's wide pitch moves the screw forward quickly per revolution and grips the fiber matrix of engineered panels without the high radial pressure that causes splitting near edges. Nibs on the underside of the washer head cut into the panel face as the screw seats, helping the head land square and flat rather than riding proud on one side. The combo drive recess accepts both a #2 Phillips and a #2 square bit. The square recess is designed to hold the screw on a correctly sized bit for placement, though actual retention depends on bit fit.
Cabinet shops running mixed-thickness assemblies keep this length on hand specifically for the joints where standard 1-1/4 inch screws leave too little bite. Furniture manufacturers assembling drawer boxes, nailer strips, and sub-components in engineered panels use the turbo thread and lubricated finish to maintain driver speed across shifts. Installers working in the field — closing in cabinet boxes, adding blocking, or securing face-frame sections to plywood backings — value the combo drive because it works with whatever bit is already in the driver. The 5000-piece box is sized for shops with real volume needs, not occasional use.
A washer head bears against the panel surface rather than sinking into it, which distributes clamping load across a wider footprint. That makes it a better fit for joining panels where pull-through resistance matters more than a flush, filled finish.
The lubricant reduces friction between the thread and the material as the screw drives. This lowers the torque your driver has to apply, which reduces heat buildup at the bit, slows bit wear, and makes it easier to drive consistently through a long production run.
It works with any drill driver, impact driver, or production screwdriver that accepts a #2 Phillips or #2 square bit. The lubricated finish and turbo thread make it forgiving across different tool speeds.
Turbo thread is designed for particleboard, MDF, plywood, and solid wood. The wide-pitch profile reduces driving torque in all of these and provides strong pull-out resistance in the fiber matrix of engineered panels.
This screw is intended for interior cabinet and furniture assembly. It is not rated for exterior use or prolonged exposure to moisture.
When the joint calls for more thread engagement than a 1-1/4 inch screw delivers but a 1-1/2 inch screw is too long for the stack, the Würth #8 x 1-3/8" Washer Head Assembly Screw is the straightforward answer — lubricated, turbo-threaded, and packed 5000 to the box for shops that measure output in cabinets per day.
