The Quickscrews #8 x 1-1/4" flat head assembly screw is a coarse-thread wood screw built for joining 3/4-inch panels, face frames, and cabinet components. It combines a Type 17 Auger point, underhead nibs, and a #2 square drive in a black finish, packed 9000 to the box for production use.
At 1-1/4 inches, this screw is matched to the thickness math of common 3/4-inch stock. Driving through one 3/4-inch panel into a second leaves just enough thread buried for a solid grab without punching through the far face. That proportion shows up repeatedly in cabinet work: attaching a shelf cleat to a side panel, fastening a back nailer, securing a drawer-bottom support, or pulling a partition to a cabinet wall. The coarse thread gives each of those joints the bite it needs in plywood, MDF, pine, and similar shop materials. For hardwood face frames, a fine-thread screw is the right call; this coarse-thread version is the one to reach for when the substrate is a sheet good or softwood.
The Type 17 Auger point sets this screw apart from a standard sharp-point flat head. The extended flute at the tip acts as a chip channel, pulling fiber out of the hole rather than compressing it against the shank walls. That matters most in dense composites and tight-grained softwoods where a plain sharp point raises driving torque and splitting risk. Once the screw is seated, the underhead nibs take over: they rotate into the wood surface and carve a countersink that matches the head taper, so the flat head drops flush without requiring a separate countersink drill pass. The #2 square drive completes the picture by transferring torque cleanly at the high end of a driver's range, where a Phillips would start to cam out.
A 9000-piece box is a production quantity, and that is the environment this screw fits. Cabinet shops building frameless boxes, millwork operations fastening cleats and nailers, and furniture manufacturers joining case components all move through short-length screws quickly. The black finish keeps the head visually recessive in cabinet interiors finished in dark melamine or painted white — the low-gloss black blends better than bare zinc in either setting. For installers pulling screws off a belt clip, the square drive's positive bit retention reduces dropped screws in tight bays and overhead installs.
Yes. The 1-1/4-inch length gives enough thread engagement in the second layer of 3/4-inch plywood without breaking through. The coarse thread holds well in the cross-ply fiber structure of plywood.
In most softwoods, plywood, MDF, and particleboard, yes. The nibs mill a seat for the flat head as it drives down. In very hard species, a pre-drilled countersink will give a cleaner result.
This is a coarse-thread screw. Hardwood face frames call for a fine-thread screw to prevent splitting and get adequate thread grip in dense grain. Use this one for softwood, plywood, MDF, and particleboard applications instead.
A #2 square drive bit. The square recess is designed to hold the screw on a correctly sized bit, which helps with placement in tight cabinet interiors.
Yes. The black finish is a good match for dark melamine interiors and blends well in painted cabinet boxes. It is an interior finish; this screw is for dry indoor applications.
When the job is cabinet boxes, shelving, or millwork and the screw count is measured in thousands per week, the Quickscrews #8 x 1-1/4" gives a flat head, a clean-driving auger point, and a square drive in the quantity that keeps the bin full.
