The Würth #8 x 1-1/2" washer head assembly screw is a lubricated, turbo-thread fastener sized for panel joinery, cabinet box assembly, and furniture manufacturing where a 1-1/2-inch screw matches the combined stock thickness. The wide washer head distributes clamping load across the surface, and the combo drive accepts either a #2 Phillips or a #2 square bit — whichever is already in the driver.
At 1-1/2 inches, this screw is well matched to panel-to-panel joints where two pieces of 3/4-inch stock meet at a face or edge, and to single-panel attachments into a backing member where penetration depth matters. Cabinet box carcass assembly, furniture panel connections, drawer box construction, and shelf-pin backing are all applications where this length earns its place. The washer head stays on the surface rather than countersinking, so it works best in interior faces, backs, and locations where the head will be covered or is otherwise out of sight.
The turbo thread profile uses a wider pitch and an aggressive cutting geometry that reduces the number of revolutions needed to pull the screw to depth. Paired with the lubricated finish, driving resistance drops noticeably on long production runs through particleboard and MDF — materials that generate high friction against a standard thread. The washer head adds bearing area at the surface, and the underhead nibs mill the material cleanly as the head seats, reducing the torn or raised surface fiber common with plain flat or pan heads driven into laminated panels.
This screw is sized and configured for shops that assemble cabinet boxes, furniture carcasses, and ready-to-assemble panel goods in volume. The combo drive means the line does not stop when one driver type is unavailable — a #2 square bit and a #2 Phillips bit both engage the same recess. The 5,000-piece pack supports extended production without mid-run restocking. For shops working primarily in engineered panels and softwood at the 3/4-inch-plus stock thickness range, the #8 x 1-1/2" is a workhorse size that covers the majority of interior panel joints.
Yes. The single recess is shaped to accept either a #2 Phillips or a #2 square bit. You do not need a separate screw for each driver type.
The underhead nibs mill the surface material as the head seats, producing a cleaner, flatter bearing surface. This matters most in laminates and melamine-faced panels where a plain head can lift or tear the facing.
This screw uses a turbo thread — an aggressive coarse-pitch geometry — and a sharp point. That combination is well suited to softwood, particleboard, MDF, and plywood. For hardwood face-frame joinery such as maple or oak, a fine-thread screw with a Type 17 point is the better fit.
The lubricant is applied to the thread and point surfaces. It reduces friction as the screw drives, which lowers torque demand and helps prevent heat buildup in the material during high-volume installation.
The sharp point self-starts in softwood, particleboard, and MDF without a pilot hole. In denser materials or when driving close to an edge, a pilot hole reduces the risk of splitting.
When cabinet box assembly, furniture panel joinery, or production woodworking calls for a 1-1/2-inch washer head screw that works with the bits already on the floor, this Würth assembly screw delivers without slowing the job down.
