This Würth #8 x 1-3/4" flat head assembly screw pairs a Type 17 Auger point with a coarse thread and a combo drive recess to handle cabinet carcass assembly, drawer box construction, and general woodworking joinery in softwood and engineered panel stock. The 1-3/4" length gives full thread engagement through typical 3/4-inch panel material into a second member, making it a practical everyday screw for production cabinet shops.
The 1-3/4" dimension is a workhorse length in cabinet box and drawer construction. It reaches comfortably through a 3/4-inch face or side panel and bites into the adjacent member with enough thread engagement to hold the joint under real load. That makes it a natural fit for attaching cabinet backs to case sides, assembling drawer box corners in plywood or Baltic birch, and fastening interior dividers and shelving cleats where a shorter screw would leave too little thread in the second piece. The coarse thread pattern adds pull-out resistance in particleboard and MDF, which is where most production cabinet boxes live.
The flat head profile sits flush with the panel surface after driving, keeping interior cabinet faces clean and ready for finish. The milling nibs on the underside of the head cut their own countersink recess in softwood, plywood, MDF, and melamine as the screw seats, which removes a separate prep step on the production line. The black finish reduces the visual contrast between the screw head and dark-stained or painted cabinet interiors, so fastener heads in exposed locations blend rather than stand out.
Cabinet shops running plywood or sheet-good carcasses in volume are the core user here. A 4800-count box supports extended production runs without frequent restocking interruptions. Custom woodworkers building drawer boxes, furniture carcasses, and shelving units in MDF or plywood will find the combo drive recess useful when the shop runs a mix of Phillips and square-drive tools. The Type 17 Auger point holds up in denser engineered panels where a standard sharp point would require noticeably more torque to seat the head flush.
Yes. The same recess accepts a #2 Phillips or a #2 square bit. The square recess is designed to hold the screw on a correctly sized bit for one-handed placement, which depends on using a properly fitting bit.
The Type 17 Auger point has an extended flute at the tip that removes wood fiber and chips as the screw drives in. This lowers the torque needed to fully seat the screw and reduces the risk of splitting, particularly in denser engineered panels and plywood.
In most softwood, plywood, MDF, and particleboard applications, yes. The milling nibs cut their own countersink recess as the head seats. In very hard or thin stock, a shallow pilot countersink may still help achieve a cleaner result.
No. The black finish on this screw is suited for dry interior woodworking. For exterior or pressure-treated lumber applications, choose a screw rated with an ACQ-compatible corrosion-protection coating.
Yes. Coarse thread provides better pull-out resistance than fine thread in low-density engineered materials like MDF, particleboard, and melamine-faced panel stock. Fine thread is the better choice for hardwoods.
At 4800 screws per box, this Würth assembly screw is stocked for shops that drive fasteners in volume, not by the handful. The right length, the right thread, and a drive that works with both bits you already own.
