This Würth #8 x 1-1/4-inch flat head assembly screw is built for cabinet and woodworking applications where fastening into 3/4-inch material is the everyday job. The combination of a Type 17 Auger point, coarse thread, flat head with milling nibs, and #2 Phillips drive delivers clean starts, flush seating, and consistent holding power across softwoods, hardwoods, and engineered panels.
At 1-1/4 inches, this screw is sized for applications centered on 3/4-inch material. It reaches through a face panel and bites solidly into the substrate behind it, which makes it a natural fit for attaching drawer box components, fastening cabinet backs into rabbets, and securing interior cabinet panels where a longer screw would blow through or a shorter one would under-penetrate. The length also suits light hardware backing and general casework joinery in plywood, MDF, and particleboard. For shops running a high volume of 3/4-inch sheet goods, this is a stock-the-bench size that handles a wide range of repetitive assembly tasks without a length change.
The flat head seats flush with the material surface, which matters anywhere the screw will be visible or where a proud head creates a clearance problem. The milling nibs on the underside of the head do the countersink work as the screw is driven, removing the need for a separate prep step in most softwoods and engineered panels. The Type 17 Auger point extends that efficiency to the entry: the fluted tip clears chips at startup, lowers the torque needed to drive through denser cabinet materials, and reduces the splitting risk that a plain sharp point can cause in tighter-grained hardwoods or thin-edge situations. Together, the nibs and auger point are what allow this screw to go from bit-contact to flush-seated in a single motion on most interior cabinet substrates.
Cabinet shops running production on frameless or face-frame casework keep this size loaded in a dedicated driver for drawer box and panel work. Installers assembling pre-built cabinet runs on site reach for it when fitting backs, adding blocking, or securing panels where a quick, clean countersink matters. Furniture makers working in plywood and MDF find the nibs and auger point reduce the setup steps between layout and driving. The #2 Phillips drive means any shop or site crew can run it without a dedicated bit, and the box of 1,000 keeps pace with production quantities without the overhead of reordering mid-run.
In most softwoods, plywood, MDF, and particleboard the nibs mill a clean countersink as the screw seats, so a separate countersink step is usually not needed. In dense hardwoods, a shallow pre-countersink can help the head seat cleanly without stress around the hole.
Yes. Coarse thread provides better pull-out resistance in low-density engineered panels like MDF and particleboard than fine thread does, because the wider thread form grabs more material fiber volume per revolution.
The zinc finish is suited to dry indoor environments. For applications with regular moisture exposure, a screw with a more robust corrosion-resistant coating is a better fit.
The Type 17 Auger point has a fluted tip that cuts and removes wood fibers as the screw enters the material. A standard sharp point displaces fibers without clearing them, which increases driving torque and splitting risk in denser materials.
This screw has a flat head and coarse thread. For hardwood face-frame joinery, a fine-thread screw with a pan or washer head is the standard recommendation because coarse thread can reduce holding power in hardwood and the flat head geometry is not optimized for pocket-hole face-frame work. This screw is well matched to softwood and engineered panel assembly.
When 3/4-inch stock is the constant in your workflow, this Würth #8 x 1-1/4-inch flat head assembly screw covers the width of tasks that length demands, with the nibs, auger point, and Phillips drive to keep each one moving without extra setup steps.
