The Würth #8 x 1" flat head assembly screw is a coarse-thread, Phillips-drive fastener sized for applications where a longer screw would over-penetrate. The 1-inch length keeps the tip inside thinner panels and backing materials while the flat head countersinks flush for a clean surface. A lubricated finish reduces driving torque, and the 1000-piece box keeps production runs moving without frequent restocking.
One inch is a practical length when the combined stock at the fastening point is thin. Attaching a drawer guide strip or a hardware mounting block to a 3/4-inch panel, fastening a back panel to a shallow ledge, or securing interior shelf cleats are situations where a longer screw creates risk of tip blow-through or surface marking on a finished face. The flat head countersinks cleanly for a flush result that does not interfere with drawer travel, door clearance, or laminate surfaces. Cabinet shops also reach for this length when fastening into pre-bored hardware locations in melamine and laminated particleboard, where thread engagement across the full 1-inch depth is enough and a longer screw would exit the panel.
The lubricated finish on this screw reduces surface friction between the thread and the substrate as the screw seats. In a production environment where a driver is cycling through hundreds of fasteners per shift, lower driving torque translates to less bit wear and less fatigue. The finish is applied to the steel shank and threads. This screw is designed for interior woodworking, cabinetry, and millwork in dry conditions. It is not rated for outdoor use or contact with pressure-treated lumber.
This screw suits production cabinet shops assembling interior components from engineered panels, softwood, and sheet goods. The #2 Phillips drive matches the standard bits most shops already run, and the 1000-piece box size supports a full day of assembly without a restock interruption. Installers doing interior trim, cabinet hanging, or hardware mounting in finished spaces will find the 1-inch length useful for applications where reach into the wall or panel needs to stay controlled. For hardwood face frames or dense solid lumber, consider a fine-thread or Type 17 point variant from the same family to reduce splitting risk.
In softwood, plywood, MDF, and particleboard the sharp point typically self-starts without a pilot hole. In dense hardwood or locations very close to an edge, a pilot hole reduces splitting risk.
No. The lubricated steel finish is suited for dry indoor conditions. For exterior work or contact with pressure-treated lumber, select a corrosion-resistant coating such as a hot-dip galvanized or ACQ-compatible option.
In softwood and medium-density panels, the flat head typically countersinks as it seats. In harder materials or melamine-faced panels, a pre-drilled countersink improves the finish and reduces surface chipping around the head.
The lubricant reduces driving friction, which lowers torque demand and decreases bit wear during repetitive fastening. It does not add meaningful corrosion resistance beyond what the base steel provides.
Choose the 1-inch when tip penetration must stay within a thin panel or when combined stock at the joint is 3/4 inch or less. If the joint involves two layers of 3/4-inch material or requires deeper thread engagement for holding strength, a longer length is the better fit.
The Würth #8 x 1" flat head assembly screw gives interior woodworking shops a reliable, production-ready fastener for thin-stock applications where flush seating, controlled penetration, and low driving friction matter most.
