The Würth #8 x 1-1/4-inch Flat Head Assembly Screw is a high-volume production fastener for cabinetry, furniture assembly, and woodworking shops. The 1-1/4-inch length is matched to the thickness of standard 3/4-inch cabinet panels and face material, making it a go-to size for box assembly, interior panel joinery, and drawer construction. Lubricated turbo thread, a sharp point, flat head with nibs, and a combo Phillips/square drive round out a screw built for consistent, fast installation across a full production run.
At 1-1/4 inches, this screw is engineered for the most common thickness in cabinet and furniture work: 3/4-inch sheet goods. That dimension shows up in cabinet side panels, bottom panels, shelving, drawer box sides, and secondary interior framing. The screw penetrates cleanly through the face panel and anchors into the adjacent member with enough thread engagement to hold the joint tight without blowing through the back face. For shops that build primarily from 3/4-inch plywood, melamine, or MDF, this length handles the repetitive interior joinery that makes up most of the fastener volume on any given job.
The turbo thread geometry is designed for faster starts and lower resistance throughout the drive. Paired with the lubricated coating, the screw moves through engineered panels and softwood with noticeably less torque demand than an uncoated standard-thread screw. That matters in production: lower torque means less heat at the bit, less stress on the driver motor, and fewer stripped heads over the course of a long run. The flat head with nibs does not need a pre-bored countersink. The milling nibs cut the seat as the head descends, leaving a flush finish in melamine, MDF, plywood, and solid wood without a separate drilling step.
This screw is most at home in production cabinet shops, millwork operations, and furniture manufacturers that build in volume and need a reliable, fast-driving interior fastener in quantity. The combo drive recess accepts a #2 Phillips or a #2 square bit, so operators can run with either without a changeover. The 7,500-piece box supports extended runs without frequent reordering. For interior panel-to-panel joints, drawer box construction, and cabinet carcass assembly in 3/4-inch stock, this is the size and spec that shows up most often in that work.
For a face-to-edge joint between two 3/4-inch panels, a longer screw — typically 1-5/8 to 2 inches — gives better thread engagement in the edge grain of the second panel. The 1-1/4-inch length is best suited for fastening through one 3/4-inch panel into a second member where full penetration depth is not required, such as a bottom panel into a side panel dado or a back panel rabbet.
Yes. The sharp point self-starts in particleboard, and the flat head with milling nibs seats flush in melamine without chipping the laminate surface around the head. The lubricated turbo thread reduces the torque needed to drive through the denser particleboard core.
The combo recess accepts a #2 Phillips bit or a #2 square bit. Either fits the same recess, so there is no need to change bits when switching between drivers.
This screw has a sharp point and a turbo thread, which is a coarse, aggressive thread geometry. That combination is not recommended for hardwood face-frame work, where the risk of splitting tight-grained wood is real. For hardwood face frames, a fine-thread screw with a controlled point is the appropriate choice.
The lubricant is applied to the thread and point surfaces to reduce driving friction. In most wood glue applications, the contact area for adhesion is the wood-to-wood surface, not the screw shank, so interference is minimal. If the joint relies on adhesive at the screw hole itself, wipe the assembly area clean before applying glue.
This SKU is packed 7,500 screws per box.
When the material is 3/4-inch and the work is cabinet carcass, drawer construction, or interior panel joinery, the 1-1/4-inch length keeps the screw in the joint where it belongs. Add turbo thread, a lubricated finish, self-seating nibs, and a combo drive that works with the bit already in the driver, and this box of 7,500 is ready to run.
