The Würth #7 x 2-1/4" drywall screw is a coarse-thread, bugle head fastener designed for securing gypsum board to wood framing where extra penetration depth is needed. At 2-1/4 inches, this screw is suited for double-layer drywall applications, thicker substrates, and situations where a standard 1-5/8" screw falls short.
Most single-layer drywall work calls for a 1-5/8" screw. The 2-1/4" length steps in when the assembly gets thicker: two layers of 1/2" board stacked for improved fire or acoustic ratings, a layer of drywall over a resilient channel, or a repair patch built up over existing material. The extra length ensures the screw reaches well into the wood stud behind the assembly, maintaining holding power through the full thickness of the build-up. For crews doing commercial ceilings or remediation work involving double-layer systems, having this length on hand prevents the job from stopping while someone sources a longer screw.
These three details work as a system. The bugle head curves up from the shank gradually, which lets it compress the gypsum board face slightly and seat below the surface without punching through the paper or mushrooming above it. That clean dimple is what joint compound fills correctly. The sharp point starts the screw without a pilot hole and threads it through the gypsum layer quickly. The coarse thread then grabs the wood framing and cinches the board tight. None of these elements are decorative — each one directly affects whether the finished wall looks right and holds reliably.
This screw is for interior, dry-condition installation into wood studs or wood backing. It is not rated for metal framing, which requires an S-type fine-thread screw with a self-tapping point. The black finish suits controlled indoor environments; for areas with elevated moisture, a screw with a heavier corrosion-resistant coating is a better choice. The 1000-piece box works well for a full room or a multi-room project, keeping the bucket stocked through the job without frequent restocking trips.
The 2-1/4" length is intended for assemblies where two layers of drywall are stacked, or where the board is going over resilient channel or another base layer. The longer screw reaches fully into the wood stud behind the assembly, where a 1-5/8" screw may not achieve adequate penetration.
No. This is a coarse-thread W-type drywall screw intended for wood framing only. Metal stud work requires an S-type fine-thread screw with a self-tapping point designed to cut through steel.
Overdriving breaks the gypsum board face paper, which weakens the fastener's holding grip and leaves a hole that joint compound does not bridge cleanly. Set the driver clutch or depth-setter so the head dimples just below the surface without punching through.
The black finish provides standard indoor corrosion resistance for dry framing conditions. In areas with consistent moisture exposure — behind tile, in steam rooms, or in unconditioned spaces — specify a screw with a heavier protective coating.
This box contains 1000 screws, sized for full-room and multi-room drywall projects.
When the assembly calls for extra depth, the Würth #7 x 2-1/4" drywall screw handles it cleanly — bugle head seats flush, coarse thread holds in wood framing, and the length covers the build-up so the finished wall is solid from face to stud.
