The Würth #8 x 2-3/4" flat head assembly screw is built for cabinet and panel joinery where depth matters. The 2-3/4" length gives adequate thread engagement through thicker stock combinations, a double panel face, or layered material, while the lubricated turbo thread, flush-seating flat head with nibs, and combo drive keep installation fast and clean.
Most assembly screws in a cabinet shop get used at 1-1/4" or 1-5/8". The 2-3/4" length is the one you reach for when the joint calls for more. Attaching a thicker face frame to a deeper cabinet side, fastening through a doubled panel, building a bench or cabinet base where two layers of plywood meet, or securing a back panel into a frame with meaningful depth — these are the spots where shorter screws come up shy and a longer screw provides the thread engagement the joint actually needs. At 2-3/4", the #8 gauge keeps the shank proportionate; you get depth without a screw so heavy it risks splitting the surrounding stock.
The turbo thread profile is wider-pitch and more aggressively angled than a standard thread, which translates to lower driving torque per revolution. Pair that with the lubricated finish — a dry-to-touch coating applied to the threads and shank — and the screw moves into material with noticeably less resistance. That matters most during a long production run where driver fatigue and bit wear add up. The flat head carries small nibs on its underside. As the head seats, those nibs cut into the wood surface and clear a shallow recess, so the head ends up flush rather than proud. In melamine, hardwood face frames, and solid-wood cabinet parts, that flush seat matters for fit, finish, and the parts that follow.
This screw suits production cabinet shops building carcasses and frames from plywood, MDF, melamine, and hardwood. It also works well for finish carpenters assembling built-ins, shelving units, or face-frame components on site, where the combo drive means one bit covers whatever is already loaded in the driver. The 1000-piece box supports shop use without constant reordering. For interior wood assembly — dry, controlled environments — the lubricated finish and steel construction are appropriate. This is not an exterior screw.
The 2-3/4" length provides deeper thread engagement when joining thicker material combinations — doubled panels, thicker face-frame stock, or cabinet bases built from two layers of plywood. Shorter screws may not reach enough material to hold the joint firmly under load.
In most wood and wood-based panels, the sharp point self-starts without a pilot hole. In very dense hardwood or close to an edge, a pilot hole reduces the risk of splitting.
The lubrication is applied to the threads and shank as a dry coating. It lowers friction as the screw is driven, which reduces the torque needed and makes the screw less likely to strip at the head in harder material.
Yes. The combo recess accepts a #2 Phillips or a #2 square bit. Either driver type engages the same recess, so you can use whichever is already loaded in your driver.
No. This screw is designed for interior wood assembly. It is not rated for exterior exposure, high-humidity environments, or contact with pressure-treated lumber.
When the joint is thick enough that standard-length screws fall short, the Würth #8 x 2-3/4" assembly screw gives you the reach, the low-friction drive, and the clean flat-head seat to keep production moving.
