The Würth #6 x 1-5/8" flat head drywall screw pairs a twinfast double-lead thread with a #1 square drive and sharp point for quick, consistent installation into wood framing. At 1-5/8 inches, this screw is sized to penetrate standard 1/2-inch gypsum board and seat firmly in the stud behind it, making it a natural fit for interior wall and ceiling work on wood-framed assemblies.
At 1-5/8 inches, this screw threads through 1/2-inch gypsum board and bites deep enough into standard wood framing to hold the panel securely through seasonal movement and normal structural loads. It also works well attaching 1/2-inch sheathing, thin wood panels, and similar interior substrates to wood backing where a shorter screw would under-penetrate and a longer one would risk breaking through the far face of narrow framing members. Interior partition walls, ceilings over wood joists, and shop-built assemblies with 1/2-inch sheet goods are all natural applications for this length.
The twinfast thread runs two helical leads starting at offset positions on the shank, so the screw advances twice the distance per revolution compared to a single-lead thread of the same pitch. In a production setting, that means less time per fastener and less motor wear when you are driving hundreds of screws in a session. The #1 square drive complements this by staying engaged under the torque of a cordless driver or screw gun without the cam-out tendency that slows installation with a cross-head drive. The sharp point eliminates any need for pre-drilling into softwood framing and gets the screw started squarely on the first contact.
This screw is built for dry, indoor applications on wood framing. The black finish handles standard interior conditions, and the flat head seats into the gypsum paper cleanly so joint compound can be applied directly over the dimple. A box of 1,000 is sized for the volume a drywall crew or production cabinet shop needs on hand, without the waste of oversized bulk quantities. If the work involves metal studs rather than wood, a fine-thread S-type drywall screw is the correct choice instead.
Yes. This length penetrates the 1/2-inch board and gives adequate bite into the wood stud behind it, which is the standard pairing for interior wall and ceiling assemblies on wood framing.
It uses a #1 square drive bit. Make sure the bit is correctly sized for the recess — a worn or off-spec bit will reduce the engagement advantage the square drive provides.
The twinfast design has two thread starts rather than one, so each full rotation of the driver moves the screw forward twice as far. That adds up quickly when you are setting hundreds of fasteners in a day.
No. This is a coarse-thread, sharp-point screw for wood framing. Metal stud work calls for a fine-thread S-type drywall screw with a self-tapping point designed to engage thin-gauge steel.
No. The black finish on this screw is rated for dry indoor conditions. Exterior or wet-area work requires a corrosion-resistant finish such as galvanized or a rated exterior coating.
The Würth #6 x 1-5/8" drywall screw gives interior work crews and production shops a fast-driving, reliable fastener in the length that matches standard 1/2-inch board over wood framing, backed by a 1,000-piece box that keeps supply ahead of the job.
