This Würth #8 x 2-1/2" drywall screw is a coarse-thread, bugle-head fastener for attaching gypsum board to wood studs and joists in interior walls and ceilings. The 2-1/2 inch length provides solid thread engagement through standard 1/2-inch or 5/8-inch board into wood framing, making it the go-to size for single-layer drywall installation.
At 2-1/2 inches, this screw is well matched to single-layer 1/2-inch or 5/8-inch drywall over wood framing. After passing through the board, there is enough shank left to achieve solid thread engagement in the stud without breaking through the back side of typical 1-1/2-inch dimensional lumber. That penetration depth is what the installation standard calls for, and this length delivers it without overdriving or splitting the stud. For double-layer assemblies or thicker substrates, a longer screw would be the appropriate choice.
The bugle head's curved underside transitions smoothly from the head face to the shank, letting the screw dimple cleanly into the board face without cutting the paper. A torn paper face weakens the joint tape bond and has to be addressed before finishing, so the head geometry here matters as much as the length. The coarse thread is optimized for wood fiber, providing the pull-out resistance needed when the board is fastened to dimensional lumber or engineered wood framing. The sharp point self-starts in wood so there is no need to pre-drill or reposition the bit before driving.
This is a straightforward interior drywall fastener for residential and light commercial construction. It belongs in wood-framed walls and ceilings where the framing is dimensional lumber, LVL, or similar engineered wood. Finish carpenters and drywall crews who hang board on wood framing will reach for this size most often. It is not the right choice for metal stud framing, which requires a fine-thread S-type screw, and the black finish is intended for dry indoor conditions only.
No. This is a coarse-thread screw engineered for wood framing. Metal stud work requires a fine-thread S-type drywall screw whose threads are designed to bite into steel. Using this coarse-thread version in metal studs results in poor thread engagement and weak holding power.
Yes. The 2-1/2 inch length passes through 5/8-inch board and achieves adequate thread engagement in the wood stud behind it, making it suitable for single-layer fire-rated assemblies on wood framing. Always confirm the required fastener schedule with the assembly specification.
A standard #2 Phillips bit. Most drywall dimpler attachments ship with a #2 Phillips bit already installed, so no separate bit is needed for the vast majority of setups.
The black finish on these screws is suited to dry interior environments. For rooms with elevated humidity such as bathrooms or laundry areas, verify the finish meets your project requirements, or specify a screw with a higher corrosion-resistance rating for that application.
Each box contains 1000 screws.
When the framing is wood and the board is standard single-layer gypsum, this 2-1/2 inch Würth drywall screw covers the application cleanly, with the bugle head, coarse thread, and sharp point working together to keep installation fast and the finished surface ready for tape and mud.
