The Würth #10 x 4" bugle head drywall screw is a coarse-thread, black, Phillips drive fastener sized for attaching gypsum board to wood framing in thicker wall assemblies, double-layer drywall applications, and anywhere a longer screw is needed to reach solid stud backing.
A 4-inch drywall screw is the right call when the standard 1-5/8" or 2" screw does not reach. Double-layer drywall ceilings and walls, sound-dampening assemblies with resilient channel, and furring strips over masonry or existing finishes all create combined thicknesses where extra length is the difference between a screw that holds and one that floats in the substrate. This screw gives enough thread engagement in the stud to hold the assembly securely without shimming or switching to a different fastener mid-job.
Coarse thread is the correct choice when the framing is dimensional lumber, LVL, or engineered wood studs. The wider thread pitch bites into wood fibers efficiently and resists pull-out without the pre-tapping that fine-thread screws require in wood. The bugle head works alongside the thread: as the screw reaches depth, the curved underside of the head guides it into a clean dimple just below the paper surface. That dimple is exactly what joint compound needs to create a smooth, invisible finish.
Drywall hangers working on fire-rated assemblies, remodel contractors adding a second layer over existing drywall, and finish carpenters attaching thick panels to wood framing reach for 4-inch drywall screws when shorter lengths leave too little bite. Cabinet shops installing wall panels over existing surfaces and soundproofing contractors building double-stud walls both keep this length in stock. The 1000-piece box supports a full day of hanging without restocking mid-project.
No. Coarse-thread drywall screws are designed for wood framing. For metal studs, use a fine-thread S-type drywall screw, which has the thread geometry to cut into steel.
A 4-inch length is appropriate for double-layer drywall, resilient channel assemblies, and other situations where combined material thickness requires deeper penetration to reach solid wood framing.
The bugle head is specifically shaped to seat cleanly without tearing the paper face. Drive to a shallow dimple just below the surface, not so deep that the paper breaks.
This is an interior screw. The black finish is not rated for outdoor exposure or contact with ACQ pressure-treated lumber. Use an exterior-rated fastener for those applications.
A standard #2 Phillips bit fits this screw. Use a drywall screwgun or a drill with a depth-stop attachment to control seating depth consistently across the panel.
When the job calls for reaching through extra material into solid framing, this 4-inch Würth drywall screw delivers the penetration, thread grip, and clean seating that thick assemblies demand, packed in a 1000-piece box sized for production hanging.
