Würth #8 x 1-1/4" Washer Head Assembly Screw Combo Drive - Sharp Point Turbo Thread Lubricated, 3670000224961 500 - 500/Box

Sized Right For 3/4-Inch Stock And Fast Assembly Work

The Würth #8 x 1-1/4" Washer Head Assembly Screw is a production-ready fastener for cabinet boxes, panel joinery, and wood assembly where 3/4-inch material is the standard. A turbo thread, lubricated finish, and combination Phillips/square drive are engineered together to keep installation fast and consistent across the workday.

Key Features

• 1-1/4" length sized for common 3/4-inch panel and carcass assembly without over-penetrating the substrate.
• Washer head spreads clamping load across a wider bearing surface, reducing pull-through in engineered panels.
• Turbo thread is designed to reduce driving torque and friction during installation in wood and composite materials.
• Lubricated finish lowers resistance as the screw drives, supporting high-volume repetitive fastening.
• Combination Phillips/square drive (#2) accepts either a #2 Phillips or a #2 square bit in the same recess for flexibility on the shop floor or job site.
• Sharp point self-starts in softwood, plywood, MDF, and particleboard without a pilot hole.

Where This Length Earns Its Place

At 1-1/4", this screw is matched to the thickness most cabinet and furniture shops work with every day. Driving through a 3/4-inch panel face into a second panel edge, or fastening a panel-to-panel butt joint in a cabinet carcass, puts this length right at the sweet spot: enough thread engagement to pull the joint tight, without the tip breaking through the far face of the receiving panel. It also works well for attaching backs and bottoms to cabinet boxes, securing drawer components, and fastening wood cleats or support strips in interior casework. For shops running melamine-faced particleboard, MDF, or furniture-grade plywood, this is a go-to length for day-in, day-out assembly.

Drive, Thread, And Finish Working Together

The combination drive accepts a #2 Phillips or a #2 square bit in the same recess. That matters in shops where multiple operators are working from the same cart, or on site where bit selection is less controlled. The square recess is designed to hold the screw on a correctly sized bit for one-handed placement, which helps when positioning components alone. The turbo thread reduces the force needed to drive each screw, and the lubricated finish compounds that benefit, cutting friction through the full length of the drive stroke. Over a long run of cabinet boxes, lower driving resistance translates directly to less fatigue and more consistent seating depth. The washer head bears against the panel face with a broad, flat surface that distributes load and resists countersinking into soft panel materials.

Built For Cabinet Shops And Production Assembly

This screw is a natural fit for cabinet manufacturers, millwork shops, and furniture producers who move through material quickly and need a fastener that keeps pace. The sharp point self-starts in softwood, plywood, MDF, and particleboard without requiring a pilot hole, which removes a step in high-volume environments. The jar packaging keeps 500 screws accessible at the bench or alongside the assembly station, and the jar format is convenient for moving around the shop or carrying to an install site. This is an interior fastener for dry, climate-controlled environments.
