The Würth #8 x 1-5/8" flat head assembly screw is sized for the most common stock thickness in cabinetry and woodworking. With a #2 Phillips drive, coarse thread, Type 17 Auger point, and milling nibs under the head, it handles the repetitive assembly work that cabinet shops and installers run through every day.
Cabinet carcass assembly, drawer box construction, and panel-to-panel connections in 3/4-inch material are the natural home for this length. The 1-5/8" screw passes through one 3/4-inch panel and bites deep enough into the adjacent piece to hold the joint under typical shop loads. It also works well attaching solid-wood edge banding, securing light blocking or nailers inside a box, and fastening back panels where the material stack puts the tip in solid wood rather than open air. For shops building cabinet runs in volume, having this length on hand in a 1000-count box keeps the line moving without constant restocking.
The flat head with milling nibs means the screw seats flush with the panel face in a single pass. As the head descends, the nibs mill away the surface fibers and collect the material rather than pushing it aside, which produces a cleaner result in hardwood, plywood, and melamine-faced stock. The coarse thread is well matched to solid wood and sheet goods, gripping the fibrous or layered material matrix tightly. Zinc plating provides reliable corrosion protection in the dry indoor environments where most cabinet assembly happens. The #2 Phillips drive is a straightforward choice for shops running standard driver bits across every station.
Cabinet shops assembling production runs of kitchen and bath cabinetry depend on a screw at this length because 3/4-inch material is the default panel thickness across the industry. Millwork teams building built-ins, bookcases, and entertainment units face the same stack of panels and the same need for a screw that seats cleanly and holds without splitting the stock. Installers who assemble cabinet components on site and finish carpenters attaching wood trim components to panels also keep this length in their kits. The 1000-count box suits any of these buyers running enough volume to make single-box quantities worth ordering.
Driving through one 3/4-inch panel leaves 7/8" of thread to engage the receiving piece. That depth gives the coarse thread enough material to grip firmly without the tip blowing through a thin back panel or a narrow nailer.
The nibs are small raised ridges on the underside of the flat head. As the screw seats, they mill away the wood fibers around the head perimeter, letting the head settle flush without a pre-drilled countersink in most wood and panel materials.
Yes. The drive recess is sized for a #2 Phillips bit, which is standard across most shop and jobsite driver kits. Using the correct bit size helps the head seat cleanly and reduces the chance of cam-out when driving at production speed.
The zinc plating on this screw is rated for indoor, dry environments. It is not appropriate for exterior exposure, high-humidity spaces, or contact with ACQ pressure-treated lumber.
In most softwood, plywood, and cabinet-grade sheet goods, the Type 17 Auger point self-starts without a pilot hole. In dense hardwoods or when fastening very close to an edge, a pilot hole reduces the risk of splitting the stock.
When the material is 3/4-inch and the job is cabinet assembly, the Würth #8 x 1-5/8" flat head assembly screw is sized for the task, built for volume, and ready to run through a 1000-count box without slowing the line down.
