The Würth #8 x 3" flat head assembly screw brings enough length to bridge thicker stock, pull through layered panels, and anchor into solid-wood substrates where a shorter screw simply runs out of thread. A #2 square drive, Type 17 auger point, coarse thread, and underhead nibs make this a practical workhorse for cabinet assembly, carcass construction, and general woodworking where a flush, clean head seating matters.
Most cabinet and woodworking assembly falls into a comfortable range covered by 1-1/4" to 2" screws. When the joint involves stacked panels, thick solid-wood frames, deep carcass sides, or a fastener that needs to travel through one board and anchor solidly into a second, that range runs short. The 3" length on this screw is calibrated for those situations: enough shank to clear a thick face or panel and still deliver full thread engagement into the receiving member. Cabinet shops assembling deep base units, framers joining thick hardwood components, and millwork crews pulling heavy panels together will find the extra reach does the job that shorter screws cannot.
The #2 square drive recess is designed to seat a correctly sized bit securely, which helps keep placement controlled when positioning the screw before driving. The Type 17 auger point carries a longitudinal flute that shaves wood fiber rather than wedging it, so the screw starts without the resistance spike that often precedes splitting in denser stock. Once the screw is moving, the coarse thread pattern advances quickly through softwood, engineered sheet goods, and plywood. As the head approaches the surface, the underhead nibs cut a clean path so the flat head drops flush without tearing the surrounding material. The black finish blends into dark or painted interiors without the silver glint of standard zinc plating drawing attention to the fastener location.
A 2000-piece box suits cabinet shops, millwork operations, and busy contractors who cycle through assembly screws in volume. At 3 inches, this screw handles the heavier-duty end of cabinet carcass assembly: anchoring back panels into thick sides, pulling wide stiles into deep frames, and fastening hardware-backing blocks where depth matters. Homeowners tackling a large built-in or a full kitchen install will also find the box quantity appropriate when the job calls for consistent fastening across many identical joints.
The Type 17 auger point helps with starting in denser wood by clearing fiber ahead of the thread. That said, coarse thread is most at home in softwoods, plywood, MDF, and particleboard. In tight-grained hardwoods like maple or oak, a fine-thread face-frame screw is typically the better choice. This screw performs well in hardwood when thread engagement depth is the priority over fine-thread holding power.
In most wood-based materials — plywood, MDF, pine, and similar softwoods — the underhead nibs mill a clean countersink as the head seats, so a separate countersink step is not required. In very hard, dense materials, a pre-drilled countersink will produce a cleaner result.
A #2 square drive bit. Using a correctly sized bit matters for the drive to seat properly and hold during placement.
Yes. The flat head with nibs seats flush in panel stock, the coarse thread grips sheet goods reliably, and the black finish stays visually quiet in dark or painted cabinet interiors. The 3" length is particularly useful when the carcass sides are thick or when back-panel and structural-support fastening requires deeper penetration than shorter screws provide.
The black finish provides a low-contrast appearance against dark surfaces. It is an interior finish suitable for dry, indoor woodworking applications.
When the joint is deep, the stock is thick, or the assembly demands more thread engagement than a 2" screw can deliver, this 3" Würth flat head assembly screw keeps the work moving without compromise on drive quality or head finish.
