The Würth #8 x 1-1/2" flat head assembly screw is built for cabinet assembly, carcass work, and general woodworking joinery where the fastener needs to seat flush and hold cleanly in standard 3/4-inch material. The 1-1/2" length puts thread engagement where it counts for that stock thickness without over-penetrating the panel.
At 1-1/2", this screw reaches across a butt joint or pocket-hole angle in 3/4-inch panels and bites solidly into the receiving member. That makes it a natural fit for cabinet box assembly, shelf pin-backing reinforcement, and carcass-corner joinery where the combined stock puts material on both sides of the fastener. It also works for attaching face-frame components directly to a cabinet box side when a wider head profile and flush seat are preferred over a trim head. For thicker stock or deep structural connections, a longer length from the same family is the right move.
The flat head with underhead nibs handles countersinking in the same motion as driving. As the head approaches the surface, the nibs mill a small relief in the wood fibers and help the head seat square and flush. This is especially useful in production runs where stopping to pre-countersink every hole adds time. The Type 17 auger point extends the chip-clearing flute further than a standard Type 17, reducing the driving force needed to start and seat the screw in denser wood. The zinc finish is appropriate for interior woodworking in dry shop or residential conditions. This screw is intended for indoor use only.
Cabinet shops building boxes in volume will find the 1,000-piece count and the flush-seating flat head useful for keeping assembly lines moving. The #2 square drive bit is standard equipment in most shops, so there is no tooling change required. Custom furniture builders and millwork teams working in 3/4-inch solid wood or plywood reach for this length when they want a screw that pulls a joint tight and disappears into the surface without additional prep. Contractors setting frameless cabinets on site will appreciate the consistent head seating when fastener visibility in the box interior matters.
The 1-1/2" length passes through a 3/4-inch panel and threads into the receiving member with enough engagement to hold the joint firmly. It avoids breakthrough on the far side when driving into a second 3/4-inch panel or a solid-wood rail of similar thickness.
In most softwoods, plywood, and medium-density panels, the nibs mill a sufficient countersink as the head seats. In very hard or dense hardwoods, a light countersink pass before driving produces the cleanest result.
A standard Type 17 point has a single short flute near the tip. The auger variant extends that flute further up the point, providing more aggressive chip clearing and faster penetration in denser or thicker stock.
This screw carries a coarse thread, which is best suited for softwood, plywood, and engineered panels. For hardwood face-frame joinery in maple, oak, or cherry, a fine-thread face-frame screw is the better choice because coarse threads can lose holding power in dense hardwood grain.
The zinc finish is rated for dry interior environments. It is not suitable for exterior use, pressure-treated lumber contact, or high-humidity settings like unventilated crawl spaces.
When 3/4-inch cabinet work is the job, the Würth #8 x 1-1/2" flat head assembly screw gives production shops and working woodworkers a reliable, flush-seating fastener they can run all day without switching bits or stopping to countersink.
