This Würth #8 x 3" flat head assembly screw is sized for applications that demand full thread engagement across stacked panels, built-up frames, or thick solid-wood components. The coarse thread, sharp point, lubricated finish, and combination Phillips/square drive make it a production-ready fastener for cabinet shops and woodworking operations driving volume.
At 3 inches, this screw reaches well beyond what shorter assembly screws can anchor. That extra length makes it useful when fastening through a face frame and into a cabinet side, joining two thicknesses of sheet goods with a backing block, or securing solid-wood components where the joint depth demands thread engagement far below the surface. The coarse thread grips wood fiber across the full engaged length, so the added reach translates directly into holding power rather than just physical depth.
The combination recess accepts a #2 Phillips or a #2 square bit, whichever is already in the driver. In production settings where different crew members use different bits, that flexibility eliminates small but real delays. The flat head seats flush when driven into a countersink, and the nibs on the underside of the head shave the countersink clean as the screw seats — useful in hardwood species like maple and oak where a sharp head is needed to pull flush without tearing the surface. The lubricated finish cuts driving resistance throughout the screw's full 3-inch travel, reducing heat buildup and bit wear during long runs.
This screw is a practical choice for cabinet manufacturers, custom shops, and production woodworking operations that assemble thick panels, face frames, or multi-layer builds and need a fastener that drives consistently across thousands of pieces. The 1,500-count box keeps pace with production demand without constant restocking. It is an indoor wood fastener — reach for a coated or galvanized screw for any application with moisture exposure.
The 3-inch length is suited for joints where the fastener must pass through a thicker top workpiece before reaching the substrate — stacked panels, face frames on cabinet sides, or solid-wood members that require thread engagement deep below the surface for adequate holding power.
Yes. The combination recess accepts both a #2 Phillips and a #2 square bit. Use whichever is already in your driver.
The nibs mill a clean countersink in the surrounding wood as the head seats. In hardwoods and laminates, this allows the flat head to pull flush without a separate countersink drilling step.
No. The lubricated finish on this screw is intended for interior wood assembly. For outdoor work or pressure-treated lumber, use a screw rated for those conditions.
The lubricated finish is a dry-to-the-touch surface treatment applied to reduce driving friction. In most cabinet and woodworking applications it does not interfere with finishing or glue joints at the fastener location, but confirm with your finishing process if the screw will be near an exposed glue line.
When the job calls for a flat-seating, flush-driving assembly screw that can handle the reach of thick stock, this Würth #8 x 3" coarse-thread screw delivers the combination of drive flexibility, head geometry, and lubricated finish to keep production moving from the first screw to the last.
