This Würth #6 x 2-1/4 inch flat head drywall screw is sized for installations where standard shorter screws fall short: thicker drywall assemblies, double-layer hang work, and repairs where the fastener needs to reach well into the framing behind the board. The twinfast thread advances quickly with fewer revolutions, and the square drive holds the bit steady under the tool.
A 2-1/4 inch screw is the right reach when you are hanging double-layer drywall, adding a second layer over existing board during a remodel, or fastening into deeper framing members. Single-layer standard installations call for shorter screws, but the moment the assembly stacks up, you need a fastener long enough to bite solidly into the wood behind it. This screw handles those situations without requiring a separate fastener for the thicker sections of the job.
The twinfast double-start thread runs two helical paths simultaneously, so the screw seats in roughly half the driver rotations of a single-start thread at the same pitch. In high-volume hanging work, fewer rotations per screw adds up to measurable time savings across a full board run. The black finish is an interior coating suited to dry, climate-controlled environments. This screw is not rated for exterior, wet, or high-humidity applications.
Finish carpenters adding a skim-coat layer, remodelers dealing with existing wall assemblies, and drywall crews running repairs on thicker builds will find this length more practical than trimming down with shorter screws. The 100-count box suits targeted repair work or fills out a job where a smaller quantity of longer screws rounds out the fastener kit alongside the primary supply.
The 2-1/4 inch length provides extra reach for double-layer drywall installations, repairs over existing board, or situations where the framing sits farther behind the wall surface than a standard single-layer hang. For single-layer 1/2 inch or 5/8 inch board on wood studs, a shorter screw is typically the right call.
A twinfast thread has two helical thread starts that begin at opposing positions on the shank. The screw advances twice as far per revolution as a single-start thread of the same pitch, which means fewer driver rotations to fully seat each fastener. On a board run with many screws, that adds up to faster installation.
This screw uses a #1 square drive bit. The square recess is designed to hold the bit in the head during driving, which helps reduce cam-out compared to a Phillips-only recess.
No. The black finish on this screw is appropriate for dry interior environments only. For exterior work or areas with moisture exposure, choose a screw with a corrosion-resistant coating rated for that environment.
No. The flat head is designed to dimple into the gypsum board surface as the screw seats, creating a slight recess for joint compound fill without a separate countersink step.
When the assembly is thicker and a standard-length screw leaves you short of the framing, this 2-1/4 inch Würth drywall screw with twinfast thread and square drive gives you the reach and the speed to finish the hang cleanly.
