The Würth #8 x 1-1/4" Flat Head Assembly Screw is a coarse-thread wood screw built for cabinet shops and production environments where consistent, flush fastening in 3/4-inch material happens all day long. It pairs a Type 17 Auger point with underhead nibs, a zinc finish, and a combination Phillips/square drive that keeps assembly moving whether operators reach for a Phillips bit or a square.
At 1-1/4", this screw is matched to the most common sheet good in a cabinet shop: 3/4-inch material. That covers cabinet box sides, shelves, drawer boxes, and back-panel attachment rails. It threads deeply enough into the receiving panel to develop full holding power without punching through the far face. For shops assembling frameless box carcasses or attaching fixed shelves, this is a workhorse length that rarely needs to be swapped out during a production run. It also works well when fastening through a thinner component into a nominal 3/4-inch substrate, such as securing a 1/4-inch drawer bottom rail or a thin overlay panel to a cabinet side.
The Type 17 Auger point does more than help the screw start. The extended flute acts on a longer section of wood fiber than a standard T17, clearing material ahead of the thread and lowering the torque needed to drive the screw to depth. In hardwood maple or birch plywood — common cabinet box materials — that translates to fewer stripped heads and less stress on the driver during a full-day run. Once the screw is seated, the flat head's milling nibs take over, cutting a clean countersink recess so the head sits flush rather than proud. The combination drive means a single bin of screws works across workstations running either Phillips or square bits without any sorting.
Zinc plating provides adequate corrosion protection for interior cabinetry in dry environments. This screw is suited to kitchen and bath cabinet production, furniture assembly, casework, and shop fixtures — applications where the finished piece lives indoors. The 9000-piece box is sized for the production floor: enough volume to run through a shift or more without restocking mid-job, and compact enough to keep at the workstation rather than on a separate pallet shelf.
The Type 17 Auger has a longer, more aggressive flute than the standard T17. That extended flute clears chips over a deeper section of the screw's travel, which reduces driving torque and splitting risk — especially noticeable in dense hardwoods or thick engineered panels.
Yes. The combination recess accepts a #2 Phillips driver. It also accepts a #2 square bit. The square recess is designed to hold the screw on a correctly sized bit for one-handed placement, which can help on production lines where screws are loaded quickly.
In most softwoods, plywood, MDF, and particleboard, the nibs mill a clean countersink as the head seats, so a separate countersink step is not needed. In very dense hardwoods, a light pre-countersink can help the head seat cleanly and reduce surface tearout around the head.
The coarse thread and flat head with nibs work well in melamine-faced particleboard and MDF. The nibs help the head seat flush at the face without cracking the laminate, provided the screw is driven at consistent speed rather than at impact-driver full throttle.
No. The zinc finish is rated for dry interior applications. For outdoor, pressure-treated, or high-humidity environments, a screw with a more robust corrosion-resistant coating is the right choice.
When the work in front of you is a stack of 3/4-inch panels and a day of cabinet assembly, this Würth #8 x 1-1/4" screw delivers the point geometry, head design, and drive flexibility to keep operators moving from one box to the next without interruption.
