The Würth #8 x 1" flat head assembly screw is a short, purposeful fastener for cabinetry, hardware mounting, and panel work where the stock thickness leaves no room for a longer screw. The square drive, Type 17 Auger point, and milling nibs work together to start cleanly, seat flush, and hold without splitting.
At 1 inch, this screw is sized for applications where the combined material stack is thin: attaching a hardware mounting plate to a 3/4-inch panel, fastening a cabinet back, or securing drawer guide hardware through a 3/4-inch side. It drives fully without punching through the opposite face, which matters whenever the back of the panel will be visible or needs to stay intact. The short length also works for edge banding anchor points, face-frame shim blocks, and interior cabinet trim strips where a longer fastener would over-penetrate.
The black finish keeps fastener heads from drawing the eye in dark or painted cabinet interiors. It is an interior finish suited for dry, climate-controlled woodworking applications. The flat head profile with underhead nibs mills its own countersink in softwood, plywood, MDF, and particleboard as the screw is seated, leaving the head flush or just below the surface without a separate countersink operation. In hardwood or laminate, a pilot and countersink are still recommended for a clean result.
Cabinet shops running production lines reach for this screw when attaching drawer slides, mounting hinge backing plates, or fastening hardware to cabinet sides where the panel thickness limits screw length. Installers use it for similar hardware-mounting tasks on site. Furniture makers working with 3/4-inch sheet goods find the 1-inch length useful for edge-to-face joints in lighter assemblies. For any application where a standard 1-1/4-inch or longer screw would over-penetrate, this is the screw to keep in the bin.
In most cases, yes. The Type 17 Auger point cuts a channel as it enters, so pre-drilling is not required in plywood, MDF, and softwood. In hardwood or near very thin edges, a pilot hole reduces split risk and gives a cleaner result.
The black finish is intended for dry, indoor applications. It resists the minor humidity of a normal interior environment and will not rust under typical cabinet conditions, but it is not rated for damp or exterior use.
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.
In softwood, plywood, MDF, and particleboard the milling nibs under the head clear material as the screw seats, typically producing a flush finish without a separate countersink step. In hardwood or laminate, countersinking first gives the cleanest result.
For most hardware plates fastened to a single 3/4-inch panel, 1 inch provides enough thread engagement without breaking through the opposite face. If you are fastening through two layers or into thicker stock, consider a longer screw from this same family.
When the panel thickness sets a hard ceiling on screw length, the Würth #8 x 1" flat head assembly screw gives you a clean-starting, flush-seating fastener that does the job without over-penetrating the material.
