This Würth #8 x 1-1/2" flat head assembly screw is a production-ready fastener built for joining wood panels, cabinet components, and furniture parts where 3/4-inch stock is the standard working thickness. The combination drive recess accepts both a #2 Phillips and a #2 square bit, and a lubricated finish keeps driving torque low across long production runs.
A 1-1/2" screw lands squarely in the range used for face-to-edge joints in 3/4-inch plywood and for attaching nailers, cleats, and blocking inside a cabinet box. It drives through a 3/4-inch near panel and threads into the adjacent piece without blowing through the far face — a key consideration on melamine interiors and finished plywood where a protruding point would ruin the surface. Cabinet shops also reach for this length when securing drawer-guide support rails and light interior blocking. The #8 coarse thread pulls quickly in particleboard and MDF, both of which are common in frameless cabinet construction, so there is no need to slow the driver to build adequate thread engagement.
The combination recess accepts a #2 Phillips or a #2 square bit in the same head. On a busy assembly line or in a small shop where one driver may be running Phillips all morning and another is loaded with square bits, that flexibility cuts down idle time. The lubricated finish matters most in volume work: lower friction at the thread means the driver works less hard on each screw, and consistent resistance across hundreds of repetitions helps the operator set every head to the same depth without dialing the clutch up and down. The flat head countersinks cleanly into softwood, plywood, and engineered panels, leaving a flush surface ready for edge banding, paint, or hardware mounting.
This screw fits cabinet manufacturers, millwork shops, and finish carpenters who cycle through large quantities of fasteners on interior wood assemblies. The 5,000-piece box supports continuous production without the interruption of small-pack replenishment. Because the coarse thread and sharp point are designed for wood-based panels and softwood rather than metal or masonry, this screw is best kept to dry interior applications — it is not coated for exterior exposure or treated-lumber environments.
Yes. The 1-1/2" length is commonly used for exactly this joint — driving through a face panel and threading into the edge of an adjacent 3/4-inch piece. Plywood edges hold coarse-thread screws reasonably well, though a pilot hole reduces the risk of splitting near the veneer edge on thinner plywood grades.
No special bit is required. The recess accepts a standard #2 Phillips driver or a standard #2 square (Robertson) driver. Either works in the same head, so you can use whichever bit is already in your tool.
The lubricant is applied to the threads and shank to reduce friction as the screw drives. In practice, this lowers the torque needed to reach full seating depth, which is most noticeable when driving hundreds of screws in a session — the driver clutch holds its setting more consistently and the operator experiences less resistance variation from screw to screw.
Yes. Coarse-thread screws are the standard choice for particleboard and MDF because the wider thread spacing grips the fiber matrix of those materials more effectively than fine thread. The sharp point self-starts without pre-drilling in most panel thicknesses.
This screw is intended for interior woodworking and cabinet assembly. It is not rated for exterior exposure or for use with ACQ pressure-treated lumber. For outdoor work, choose a screw with a coating rated for exterior or treated-lumber environments.
When 3/4-inch panel joinery is the job, the Würth #8 x 1-1/2" flat head assembly screw gives a cabinet shop or millwork crew a lubricated, combo-drive fastener in the quantity needed to stay on schedule without stopping to restock.
