This Würth #8 x 1-1/4" truss head machine screw is built for mounting decorative cabinet hardware — knobs, pulls, and cup handles — to doors and drawer fronts. The 8-32 thread is the North American cabinet hardware standard, meaning it fits virtually every knob and pull sold for residential cabinetry. The 1-1/4" length is the go-to choice when hardware needs to pass through stock thicker than a standard 3/4" door panel, including layered or inset drawer fronts.
Standard cabinet pulls and knobs are designed around 3/4" door stock, and a shorter screw handles that well. The 1-1/4" length steps in when the geometry changes. Double-thick drawer fronts, applied overlay panels, inset door construction, and solid-wood furniture doors all add material between the drill hole and the hardware base. At 1-1/4", there is enough thread engagement to pull the hardware firmly against the face while keeping the screw from bottoming out or stripping the pull's barrel. It is also the right call when hardware has a thick back plate that eats into available thread length.
The screw is zinc-plated steel, which is the standard finish for interior hardware mounting work. The zinc plating provides adequate protection against light moisture exposure in a kitchen or bath environment and keeps the shank from reacting with painted or lacquered cabinet surfaces. The truss head sits flat and wide, distributing the clamping load evenly across the back of the pull or knob base without requiring a countersink in the panel. The combination Phillips/Slotted drive accepts a #2 Phillips bit for powered installation or a flat-blade driver when a drill cannot reach the screw head cleanly — a real convenience when hanging hardware on assembled cabinet boxes.
Cabinet shops running full kitchen or bath installations benefit most from the 1,000-piece pack. A single kitchen can easily consume dozens of these screws across drawer fronts and door hardware, and having a dedicated box for the 1-1/4" length means no guessing mid-install. Finish carpenters and renovation contractors working on furniture-grade doors or built-ins with thicker panels will also find this length spans the range where a 3/4" or 1" screw comes up short. Homeowners replacing hardware on painted or panel-overlay doors — where the original shorter screws no longer reach — will find this the correct replacement length.
8-32 is the North American industry standard thread for cabinet knobs and pulls. Nearly every decorative hardware manufacturer threads their products to accept an 8-32 machine screw, so this screw will fit standard knobs and pulls without any adapters or inserts.
The 1-1/4" length is the right choice when the door or drawer front is thicker than standard 3/4" stock, when an overlay or applied panel adds material, or when the hardware itself has a thick back plate. If a shorter screw is stripping out before the hardware seats firmly, a longer screw provides more thread engagement.
No. The truss head is a non-countersunk profile designed to bear flat against the back surface of the hardware or the face of the material. It does not need a countersink and should not be driven into one.
Yes. The combination recess accepts either a #2 Phillips driver or a flat-blade driver in the same recess. Both will drive the screw; Phillips is the better choice for powered installation because it provides better cam-out resistance than the slot.
The zinc finish is designed for indoor use. It is a good fit for kitchen, bath, and furniture hardware in dry or lightly humid interior environments, but is not the right choice for exterior hardware exposed to weather.
When the length fits the stock and the thread matches the hardware, installation is straightforward and the pull seats firmly without rework. The 1-1/4" 8-32 machine screw covers the installs where standard-length screws fall short.
