This Würth #8 x 2-1/4" flat head assembly screw brings together a Type 17 auger point, coarse thread, milling nibs, and a #2 Phillips drive in a length well suited to medium-depth wood fastening across cabinet boxes, solid wood components, and sheet-good panels.
At 2-1/4", this screw reaches deeper than typical 1-1/2" or 2" cabinet screws without crossing into structural-fastener territory. That extra length pays off when driving through a 3/4" panel and into a second member, joining doubled-up stock, or fastening through thicker solid wood components where shorter screws would leave too little thread engagement in the receiving piece. Cabinet carcass assembly, furniture frames, shelving units, and interior millwork all present situations where the 2-1/4" length hits a range that shorter screws can't cover cleanly.
The Type 17 auger point features an extended flute that removes wood fiber ahead of the thread, a meaningful advantage when driving repeatedly into maple, oak, or dense engineered panels. Less fiber resistance at the tip translates to lower torque demand and fewer split edges near the end grain. The milling nibs on the underside of the flat head do double duty: they relieve the wood surface as the head seats and help keep the screw from spinning back out once driven. The coarse thread engages softwood, plywood, and particleboard efficiently, and the zinc finish is appropriate for dry, indoor applications. This is an interior screw; outdoor or treated-lumber work calls for a corrosion-rated coating.
Cabinet shops running production on carcasses and face components go through assembly screws quickly, and a 1,000-piece box at this length covers the volume without constant reordering. Finish carpenters and installers who need a reliable, flush-sitting screw for solid wood and plywood joinery will find the combination of Phillips drive and nibs practical with standard tooling. The #8 gauge and 2-1/4" length also work for homeowners tackling larger furniture builds or shop projects where a medium-length wood screw with a clean head finish is the right call.
The extra quarter inch adds thread engagement in the receiving member, which matters when fastening through a full 3/4" panel into a second piece or when working with slightly thicker stock. If your joint geometry gives the longer screw room without breaking through the far face, it provides a more secure grip.
In most softwoods and sheet goods, the milling nibs cut a clean countersink as the screw seats, so a separate countersink step is not required. In very hard or brittle materials, pre-drilling the countersink produces a cleaner result.
The coarse thread provides adequate pull-out resistance in MDF and particleboard for most interior assembly applications. Driving near edges in those materials still benefits from the Type 17 auger point's chip-clearing action to reduce surface blowout.
The zinc finish is suited to dry indoor conditions. For outdoor, high-humidity, or pressure-treated lumber applications, choose a screw with a corrosion-rated coating.
A standard #2 Phillips bit drives this screw. It is the most common bit size in production shops and on jobsites, so no specialty tooling is needed.
When the job calls for a medium-depth assembly screw that seats flush, starts clean, and works with a #2 Phillips bit, this Würth #8 x 2-1/4" flat head screw covers the range — packed 1,000 to a box so production keeps moving.
