The Würth #7 x 1-5/8 inch bugle head drywall screw is a workhorse size engineered for attaching standard 1/2-inch or 5/8-inch gypsum board to wood studs. The 1-5/8 inch length puts roughly an inch of thread into the framing behind the panel, giving the head room to dimple cleanly without over-penetrating. It drives with a #2 Phillips bit and arrives packed 5000 to the box, sized for production crews and high-volume installs.
Length is the make-or-break spec on a drywall screw. Too short and the screw lacks the thread engagement needed to hold the panel securely; too long and the tip risks punching through the far face of narrow framing or catching wiring runs. At 1-5/8 inches, this screw is the standard choice for 1/2-inch gypsum board on wood studs and also handles 5/8-inch board when a little extra embedment depth is acceptable. The head seats at the right depth for a joint-compound-ready dimple without a second pass to correct over-driven fasteners. For crews moving at production pace, that consistency matters row after row.
The bugle curve on the underside of the head is what sets a drywall screw apart from a standard wood screw in this application. As the head reaches the panel face, the gradual curve transitions the clamping force across the paper facing rather than concentrating it on a sharp edge. The result is a clean dimple instead of a torn crater. Combined with the coarse thread designed for wood-stud engagement, this screw pulls the panel tight to the framing and stays put. The black finish is appropriate for the dry, climate-controlled interiors where drywall installation happens. This is an indoor screw; it is not intended for exterior or high-humidity environments.
Residential framing and finish crews hanging standard single-layer board are the core users for this size. The 1-5/8 inch length also appears in light commercial tenant improvement work where wood blocking and wood-framed partition walls are in the plan set. Remodeling contractors adding a room, finishing a basement, or patching a full wall will find the 5000-count box practical for a multi-day job rather than running out mid-wall. Cabinet shops that do occasional drywall work on their own build-outs keep a box on hand for the same reason. One important note: this screw is designed for wood studs. For metal stud framing, a fine-thread S-type screw with a self-tapping tip is the correct choice.
Yes. The 1-5/8 inch length provides adequate thread engagement in wood framing behind 5/8-inch board. Check your project's fire-assembly specification to confirm fastener schedule and spacing requirements, as fire-rated assemblies carry their own installation rules.
These are loose-packed screws, not collated strips. They are designed for a standard drywall dimpler bit or a corded screw gun with a depth-limiting nose, not an auto-feed magazine tool that requires strip-collated screws.
The bugle head is the key distinction. A drywall screw's concave underhead curve lets the head countersink through gypsum paper without tearing it. A standard wood screw with a flat or pan head would dimple unevenly and risk damaging the paper facing.
No. The black finish on this screw provides standard indoor corrosion resistance for dry interior applications. Bathrooms with direct water exposure and any exterior application call for a screw with a heavier corrosion-protective coating.
A common rule of thumb is one screw every 12 inches in the field and every 8 inches at the edges of a 4x8 sheet, which works out to roughly 32 screws per sheet. A 5000-count box covers approximately 150 sheets at that spacing, making it a practical quantity for a full room or a multi-room project.
When the length is right and the head is right, drywall installation moves without interruption. This Würth #7 x 1-5/8 inch bugle head drywall screw delivers the depth and head geometry that interior hang crews rely on, in a box quantity built for the pace of real production work.
