The Würth #8 x 1-1/2" flat head assembly screw is built for high-volume cabinet and woodworking production. A coarse thread, Type 17 Auger point, combination drive recess, and milling nibs work together to speed up assembly and deliver a clean, flush head in softwood, sheet goods, and engineered panels.
At 1-1/2 inches, this screw is well matched to common cabinet and furniture assembly joints. It drives through a 3/4-inch face or panel and achieves solid thread engagement in the second member, making it a practical choice for attaching cabinet backs, fastening shelf standards, joining box components, and similar panel-to-panel work. The length also works for securing hardware backing strips and interior mounting blocks where a shorter screw would under-penetrate and a longer one would risk breakthrough.
The combination recess accepts both a #2 Phillips and a #2 square bit without changing heads. In a production shop where multiple operators share tools, that flexibility eliminates the delay of hunting for the right bit. The flat head carries milling nibs on its bearing face, which cut a clean countersink into the surrounding material as the screw seats. The result is a flush head without a dedicated countersink drill pass, which matters when throughput is the priority.
This screw is designed for cabinet shops, millwork operations, and on-site installers working in dry interior conditions. The coarse thread pulls reliably through softwood, plywood, particleboard, and MDF — the materials that make up the bulk of production cabinet work. The zinc finish provides adequate protection for climate-controlled shop and residential interior environments. For outdoor, high-humidity, or treated-lumber applications, a corrosion-rated exterior screw is the better specification.
Yes. The combination recess accepts both a #2 Phillips and a #2 square bit, so either works in the same head without any adapter.
In most softwood, plywood, MDF, and particleboard, the milling nibs under the flat head mill a clean countersink as the screw is driven, seating the head flush. Very dense hardwood may benefit from a pilot countersink pass.
Yes. Coarse thread provides better pull-out resistance than fine thread in low-density engineered panels like MDF, particleboard, and melamine-faced substrates, which are the most common materials in cabinet box construction.
No. The zinc finish is suited to dry indoor environments. Outdoor work or contact with pressure-treated lumber calls for a screw with a corrosion-rated exterior coating.
The Type 17 Auger point carries a fluted cutting tip that clears wood fibers ahead of the thread as the screw starts. This reduces the torque needed to begin driving and lowers the risk of splitting, particularly when fastening close to a panel edge.
When your work demands a flat-head assembly screw that starts cleanly, seats flush, and keeps up with production volume, the Würth #8 x 1-1/2" delivers the length, thread, point, and drive combination that cabinet and woodworking shops rely on day to day.
