The Würth #8 x 1-1/4" flat head assembly screw is built for production cabinet and woodworking shops that join 3/4-inch material all day. Coarse thread, a Type 17 Auger point, underhead nibs, and a #2 Phillips drive combine in a screw that starts clean, seats flush, and moves through high-volume work without slowing down.
At 1-1/4 inches, this screw is the standard choice for joining 3/4-inch sheet goods and solid stock. The length gives the thread enough engagement in the receiving material to hold the joint firmly without punching through the opposite face of a panel. It suits face-frame assembly to the cabinet box, drawer box construction in plywood and MDF, shelf pin backing, and general carcass work where 3/4-inch material meets 3/4-inch material. The Type 17 Auger point clears material quickly at the tip, which matters in coarse substrates like particleboard where a plain sharp point would require noticeably more torque to start.
The flat head countersinks flush with the panel face, and the underhead nibs do the countersink work as the screw is driven. In most wood-based panels, that eliminates a separate countersink operation entirely and keeps the assembly line moving. The black finish suits dark melamine interiors, painted panels, and any application where a zinc-silver head would stand out against the surface. This is an interior assembly screw. The black coating is not a corrosion-rated exterior finish, so keep it on indoor work.
A 9000-count box is the format for shops with a real daily volume. Cabinet manufacturers, millwork operations, and high-output custom shops can load a bin at the start of the week and work without interruption. The #2 Phillips drive means no special bit inventory is required. Any driver set on the floor will run these screws, and any technician on the line already knows the bit. For shops running through fasteners in volume, a consistent screw with a predictable point, thread, and head geometry reduces the small variables that slow assembly when a screw misbehaves in the material.
Yes. When driving through 3/4-inch face-frame stock into the cabinet box panel, 1-1/4 inches provides solid thread engagement in the box without breaking through the far face of a standard 3/4-inch panel.
The Type 17 Auger point has a longitudinal flute near the tip that clears wood fibers as the screw enters the material. This reduces the torque needed to start the screw and lowers the risk of splitting in denser substrates like particleboard and hardwood.
In most wood and panel materials, yes. The nibs on the underside of the flat head mill the countersink as the screw seats, allowing a flush finish without pre-countersinking. Results can vary in very hard or very dense substrates.
Yes. The coarse thread is designed for engineered panels including MDF, particleboard, and plywood, where the wider thread pitch provides better pull-out resistance in the lower-density fiber matrix than a fine thread would.
No. This screw is intended for interior woodworking and cabinet assembly. The black finish is not rated for exterior exposure or wet environments.
When the job is 3/4-inch cabinet assembly and the output is measured in boxes per day, the Würth #8 x 1-1/4" flat head assembly screw delivers a consistent start, a flush seat, and a drive that any shop bit handles without a second thought.
