The Würth #8 x 1-1/2 inch flat head assembly screw is a coarse-thread, sharp-point fastener with a #2 Phillips drive and a black finish. It is built for cabinet carcass assembly, panel joinery, and interior woodworking tasks where a 1-1/2 inch length lands cleanly through standard 3/4-inch stock.
At 1-1/2 inches, this screw is well matched to cabinet carcass construction: back panel attachment, shelf pin strip installation, and joining 3/4-inch side panels to top and bottom rails. The flat head countersinks flush in melamine and raw plywood alike, so interior surfaces stay smooth. On furniture cases and drawer boxes built from 1/2-inch or 3/4-inch sheet goods, this length pulls joints tight without blowing through the back face of the receiving panel. It also handles interior trim blocking, dado reinforcement, and hardware backing strips where screw length needs to stay controlled.
The screw body is steel with a black finish suited to dry, indoor cabinet and woodworking environments. The black color is a practical choice in shop environments where screw heads appear inside finished cabinets: it reduces the visual contrast between the fastener and a dark or painted interior. This finish is appropriate for interior applications in controlled environments.
The box holds 7,000 screws. That volume suits cabinet shops, millwork operations, and production facilities that go through a consistent quantity of #8 x 1-1/2 inch assembly screws each week. Ordering at this quantity reduces per-screw cost and keeps the bin full during busy production cycles. The Phillips drive works with standard #2 bits available at any supply house, so there is no specialty tooling to source or stock.
For a face-to-face butt joint through one 3/4-inch panel and into a second, 1-1/2 inches gives roughly 3/4-inch of thread engagement in the receiving piece, which is solid for carcass-grade joinery in plywood and particleboard.
Coarse thread is optimized for softwoods, plywood, MDF, particleboard, and melamine-faced panels. For dense hardwood face frames, a fine-thread screw is a better match.
The flat head seats best in a pre-drilled countersink, particularly in harder substrates. In softer materials like particleboard or MDF, it will often self-countersink cleanly, but a pilot countersink produces a more consistent result across a production run.
This screw carries a black finish rated for dry interior use. It is not recommended for exterior applications or high-humidity environments.
It uses a #2 Phillips bit, the most common Phillips bit size in shop and jobsite use.
When the length, thread, and head match the joint, assembly goes faster and finished cases look cleaner. This #8 x 1-1/2 inch flat head screw is sized for the panel thicknesses that drive most cabinet and casework production, stocked in a quantity that supports a busy shop schedule.
