The Würth #8 x 1-1/4" flat head assembly screw is built for cabinet box assembly, face frame attachment, and general woodworking joinery where 3/4-inch material is the standard. The lubricated finish reduces driving friction, the combo drive accepts either a #2 Phillips or a #2 square bit, and the flat head with nibs seats cleanly without a separate countersink step.
At 1-1/4 inches, this screw hits the sweet spot for joining 3/4-inch sheet goods face-to-face or fastening a component to a single panel. It delivers enough thread engagement for a solid joint without over-penetrating the back face. Cabinet shops use this length constantly — for assembling box panels, securing interior partitions, and anchoring nailers or blocking inside a finished carcass. The coarse thread grabs quickly in plywood and MDF without requiring excessive torque, and the sharp point self-starts without pre-drilling in those materials.
The lubricated coating on the thread and shank surfaces cuts the resistance you feel when driving screw after screw through an engineered panel. In a production environment where a single cabinet run means hundreds of fasteners, lower driving torque translates directly to less hand fatigue and less wear on driver bits. The combo drive recess is designed to hold the screw on a correctly sized bit for one-handed placement — useful when you are positioning a panel with one hand and driving with the other. Both #2 Phillips and #2 square bits engage the same recess, so changing bits is optional, not required.
Cabinet shops building frameless or face-frame boxes in softwood plywood, melamine-faced particleboard, or MDF reach for this size most often. It also works well for attaching 3/4-inch backing panels, installing interior blocking, and fastening shelf standards or hardware mounting strips inside a cabinet case. Homeowners assembling ready-to-finish cabinet kits and contractors closing out kitchen or bath installs will find the 1-1/4-inch length practical for the same panel-thickness scenarios. The flat head with nibs is particularly useful in melamine and laminated panels, where it seats flush without chipping the surrounding surface the way a sharp-edged countersink sometimes can.
Yes. The combo recess accepts a #2 Phillips driver. It also accepts a #2 square bit, so either works in the same head without switching screws.
The lubricant on the threads and shank reduces the torque needed to drive the screw. Over a long production run this means faster driving, less bit wear, and less strain on your wrists and driver motor.
The nibs are small ridges on the underside of the head that mill the wood surface as the screw seats. This lets the head countersink itself flush in plywood, MDF, and particleboard without a separate countersink drill operation in most cases.
This screw has a coarse thread and a sharp point, which are best suited for softwood, plywood, MDF, and particleboard. For hardwood face frames in maple, oak, or similar species, a fine-thread screw with a Type 17 point is the better choice to prevent splitting.
Yes. The lubricated finish is suited for dry indoor assembly. It is not rated for exterior or pressure-treated lumber applications.
When 3/4-inch panel work is the core of your production, a lubricated #8 x 1-1/4" assembly screw with a combo drive and flat head with nibs keeps each joint consistent and each shift moving.
