The Würth #8 x 1-1/2" flat head assembly screw is built for production cabinet and furniture work where you need a screw that seats flush, drives fast, and draws two panels together without fighting the bit. It combines a lubricated coarse thread, a flat head with nibs, a sharp point, and a combination Phillips/square drive into one screw that runs reliably across a full shift.
At 1-1/2 inches, this screw spans a 3/4-inch panel face and buries enough thread in the receiving piece to hold the joint under load. That makes it a natural fit for cabinet box assembly: drawer box corners, dado-and-rabbet back panels, shelf-pin cleats, and rail-to-side connections where the screw enters from the inside face of the panel. It also works well for attaching light hardware backing strips, joining face-frame stock to softwood or sheet-goods carcasses, and general case goods production where 1-1/4 inch comes up short and 1-3/4 inch is more than the stack needs.
The lubricated coating reduces surface friction on the threads and under the head, so each screw reaches full seating depth with less resistance. On a production line driving thousands of screws in a shift, that difference shows up in reduced bit wear, fewer stripped heads, and less operator fatigue. The flat head carries underhead nibs that cut into wood fiber and sheet-goods surfaces as the screw is driven, pulling the head flush without a countersink drill. The combination keeps the assembly process tight: one tool, one step, flush result.
Cabinet shops running frameless or face-frame boxes in softwood, plywood, MDF, or particleboard will find this length in regular rotation. The combination drive lets crews work with either a Phillips or square bit, which matters when multiple operators share a line and bit inventory is mixed. Furniture manufacturers assembling case pieces, drawer boxes, and back panels in engineered sheet goods get the same benefit: a screw that drives fast, seats flush, and does not require a dedicated countersink pass. The 5,000-count box supports sustained production without the interruption of frequent replenishment.
The combination recess accepts a #2 Phillips or a #2 square bit. Both engage the same recess, so you can use whichever is already in the driver.
No. The nibs mill the countersink as the head seats in wood and sheet-goods substrates. A pre-drilled countersink is not required in most panel and softwood applications.
Yes. Coarse thread provides better pull-out resistance than fine thread in low-density engineered panels like MDF, particleboard, and melamine-faced board. Fine thread is intended for hardwood and metal; coarse thread is the right choice for these substrates.
The lubricant reduces friction between the thread and the substrate as the screw is driven. The practical result is lower driving torque, which helps prevent head stripping and reduces wear on driver bits during high-volume production runs.
This screw is intended for interior woodworking and cabinet assembly. It is not rated for exterior use or wet environments.
When the job calls for a flush-seating, fast-driving #8 x 1-1/2" screw that runs on either Phillips or square bits, this Würth assembly screw delivers it in a bulk count sized for the shop floor.
