The Würth #8 x 3" flat head drywall screw pairs a twinfast double-lead thread with a #2 square drive and sharp point, designed for interior panel and gypsum board work where a countersunk, flush-seated head is the goal. Packed 100 to the box.
This is an interior-use drywall screw suited to gypsum board, MDF, particleboard, and wood panel applications where a flush countersunk head is needed. The flat head seats cleanly in a pre-drilled countersink rather than self-dimpling like a bugle head, making it a practical choice when the fastener surface will be visible, filled, or painted. At 3 inches, it has enough length for thick assemblies or for driving through a panel and well into a backing member. Keep this one for dry, indoor work — the black finish is not rated for exterior or high-moisture environments.
The twinfast thread uses two helical leads starting at offset positions on the shank. Because the screw advances twice as far with each full turn of the driver, it reaches full depth in roughly half the rotations of a comparable single-lead screw. That matters in production settings — cabinet shops, millwork operations, and interior finish crews — where driving the same screw hundreds of times per day adds up. The #2 square drive supports that pace: the square recess is designed to hold a correctly sized bit securely, which reduces the driver slippage that slows single-screw placement and can mar surrounding surfaces.
This screw suits cabinet shops and finish contractors who need a reliable interior panel fastener with a flush-seated head and efficient driving geometry. The combination of twinfast thread, square drive, and flat head is practical for production assembly of MDF components, panel installations, and interior gypsum board work where countersinking is part of the workflow. The 100-piece box is sized for targeted use or for evaluating the screw in a specific application before committing to a larger quantity.
A bugle head has a curved underside that self-dimples into gypsum board without tearing the paper. A flat head has a straight conical underside and is designed to seat in a pre-drilled or pre-cut countersink, leaving a truly flush surface. Use the flat head when you want the screw to sit in a defined countersink rather than self-sink into the material.
A twinfast thread has two helical leads beginning at offset points on the shank. The screw advances twice as far per revolution, so it reaches full depth in fewer driver rotations. This reduces installation time in production applications where the same screw is driven repeatedly.
No. This is an interior-use screw. The black finish is not rated for exterior exposure or wet environments. For outdoor work, choose a screw with a galvanized or other exterior-rated coating.
Yes. The sharp point and twinfast thread drive well into MDF and particleboard, and the flat head seats flush in a countersink in those materials. For best results in particleboard edges, pre-drilling reduces the risk of material crumble near the fastener entry.
A #2 square drive bit. The square recess is designed to hold the screw on a correctly sized bit for placement, and provides positive bit engagement during driving.
When you need a flush-seating, fast-driving interior screw for gypsum board, MDF, or panel work, this Würth flat head drywall screw delivers the twinfast thread speed and square drive control to keep production moving.
