Würth #8 x 1-1/2" Washer Head Assembly Screw Combo Drive - Sharp Point Turbo Thread Lubricated, 3670000223961 500 - 500/Box

Combo Drive Assembly Screw for Drawer Boxes and Cabinet Interiors

The Würth #8 x 1-1/2-inch washer head assembly screw is built for cabinet shop production, combining a Turbo Thread, sharp point, and lubricated finish to drive fast and seat clean in drawer boxes, cabinet backs, and panel-to-panel connections where a low-profile head and controlled bite matter.

Key Features

• Washer head spreads clamping load across a wide bearing surface to resist pull-through in engineered panels and plywood.
• Turbo Thread design reduces driving torque so the screw moves through material with less resistance during high-volume runs.
• Sharp point self-starts in softwood, plywood, MDF, and particleboard without a pilot hole.
• Combo drive accepts a #2 Phillips or a #2 square bit in the same recess, so drivers can run without a bit change.
• Lubricated finish lowers thread friction further, reducing heat buildup and driving effort on long assembly runs.
• 500 screws per jar keeps the bench stocked through a full production day without reordering mid-shift.

Where the 1-1/2-Inch Length Earns Its Place

At 1-1/2 inches, this screw is sized for joints where two panels come together and you need thread engagement in both. Drawer box corners in 1/2-inch material, cabinet back panels let into a rabbet, and stretcher-to-side connections in 3/4-inch stock are all natural fits. The length gives enough thread in the second piece to hold the joint without punching through the far face. For shops running plywood or melamine drawer boxes by the dozen, this is the screw that keeps the line moving.

Drive, Thread, and Finish Details

The combo drive recess accepts both a #2 Phillips and a #2 square bit, which matters on a busy assembly floor where one operator may reach for a Phillips driver while another uses a square. Neither has to stop and hunt for the right bit. The Turbo Thread is an aggressive wide-pitch design that moves through particleboard, plywood, and MDF quickly and grips the fiber matrix firmly once seated. The lubricated coating works alongside the thread geometry to cut friction at the point and along the shank, which reduces the torque your driver has to produce and helps prevent head stripping on rapid repeat drives. The washer head profile sits flat against the panel face without countersinking, making it the right choice where a recessed head would weaken thin stock or laminate edges.

Who This Screw Is Built For

Cabinet shops building frameless boxes or running drawer production are the core user. The jar format puts 500 screws in a container that sits open on the bench or in a bin without tipping, and the lubricated finish means screws feed smoothly rather than sticking together. Installers assembling site-built casework and furniture manufacturers joining panel components will find the 1-1/2-inch length covers the joints they hit most often in 1/2-inch and 3/4-inch engineered panel work. For shops that already run Würth assembly screws, this JAR SKU fits the same workflow with an accessible pack size suited to daily use rather than full pallet stocking.

Keep the Assembly Line Running

When the joint calls for a 1-1/2-inch screw and the panel is engineered wood, this Würth washer head assembly screw handles the combination of speed, drive flexibility, and head bearing that production cabinet work demands.
