The Würth #8 x 1-5/8" flat head assembly screw is built for the joinery and panel fastening tasks that define day-to-day cabinet and woodworking production. At 1-5/8 inches, the length seats fully through standard 3/4-inch stock with enough thread engagement in the receiving piece to hold the joint without over-penetrating thin panels or back walls. A coarse thread, Type 17 Auger point, Phillips drive, and underhead nibs work together to make this a reliable production screw for shops running high volume.
Cabinet shops, millwork operations, and finish carpenters reach for a 1-5/8-inch screw when the job involves 3/4-inch sheet goods and solid wood. The length threads fully through the face piece and bites deep enough into the mating panel to create a tight, lasting joint without the tip breaking through a 3/4-inch back or nailer. Common tasks include attaching cabinet nailers, assembling drawer boxes from 1/2-inch or 3/4-inch plywood, connecting carcass parts before pocket screws reach, fastening shelf cleats, and securing face-frame components to a box. For shops running melamine-faced particleboard and MDF alongside plywood, the coarse thread handles all three substrates in the same operation without a screw change.
The Type 17 Auger point opens a clean entry channel in the wood fiber before the thread engages, which is why it reduces splitting in softwood and cuts driving torque in denser materials like MDF. The coarse thread form then pulls the joint tight as the screw advances. Nibs on the underside of the flat head mill the surface as the head seats, so in most softwoods, plywood, and MDF applications the head countersinks itself without a pre-drilled recess. That saves a tool change on the drill press or a second pass with a countersink bit. The zinc finish on the steel shank is suited to the dry, climate-controlled environments where interior cabinet work happens.
This SKU packs 3,500 screws in a pail. Pail packaging is convenient for movement around the shop or to the job site. For a production cabinet operation, 3,500 pieces at a single size means fewer reorders interrupting the build schedule. The #2 Phillips drive means any drill or impact driver already set up for drywall or hinge screws runs this screw without a bit swap. Shops that standardize on Phillips across their assembly stations will find this fits into an existing workflow without added tooling.
It threads fully through 3/4-inch stock and seats with enough thread engagement in the mating piece to hold a tight joint, while stopping short of breaking through a second 3/4-inch panel. That range makes it versatile for carcass assembly, nailer attachment, and cleat work.
Coarse thread is the right choice for softwood, plywood, MDF, particleboard, and melamine-faced panel products. It is not the preferred thread for dense hardwoods like maple or oak, where a fine thread resists splitting better.
In softwood, plywood, and MDF the nibs typically mill a clean enough seat that no separate countersink step is needed. In very hard or dense materials, a pre-drilled countersink still helps the head sit fully flush.
For softwood face frames and face frames in sheet goods, the coarse thread and 1-5/8-inch length work well. For hardwood face frames in maple, oak, or cherry, a fine-thread screw is the better match because coarse thread can split tight-grained stock.
The zinc plating is rated for dry indoor environments. It is not suited for outdoor exposure, high-humidity conditions, or contact with pressure-treated lumber.
When the work calls for a dependable 1-5/8-inch assembly screw for cabinet panels, drawer boxes, and wood frames, this Würth flat head in a 3,500-piece pail gives production shops the quantity and consistency to stay on schedule.
