Würth #8 x 1-1/4" Flat Head Assembly Screw Combo Drive - Sharp Point Turbo Thread Lubricated, 3670000108961 500 - 500/Box

Assembly Screw Sized For 3/4-Inch Stock Joinery

The Würth #8 x 1-1/4" flat head assembly screw is built for cabinet and woodworking joinery where 3/4-inch material is the standard. A Turbo Thread design, sharp point, and lubricated finish work together to keep driving fast and consistent through repeated assembly runs.

Key Features

• Turbo Thread profile reduces driving torque and friction for faster installation in wood and engineered panels.
• Combination Phillips/square drive recess accepts a #2 Phillips or #2 square bit in the same head.
• Flat head with milling nibs seats flush in the material surface without a separate countersink operation.
• Sharp self-starting point gets the screw started quickly in softwood, plywood, and light-density panels.
• Lubricated finish reduces friction at the threads and point for lower-effort driving in production work.
• 500 screws per jar with a 2-inch drive bit included in the package.

Where the 1-1/4-Inch Length Fits

A 1-1/4-inch screw lands in a practical sweet spot for cabinet and furniture assembly built around 3/4-inch sheet goods. It drives fully through a face-frame member or panel face and into the substrate with enough thread engagement to hold the joint, without punching through the back of a thin panel or creating interference in tight assemblies. This length is also a go-to for attaching light hardware backing, assembling plywood drawer components, and joining melamine or laminate panels where a longer screw would exit the far face. Shops working primarily in 3/4-inch plywood, MDF, or particleboard will reach for this size often.

Turbo Thread, Nibs, and Lubricated Finish in Practice

The Turbo Thread geometry uses a wider-pitch thread profile designed to move through wood fiber with less resistance than a standard coarse thread. Combined with the lubricated coating, the screw drives with noticeably less effort per fastener — a meaningful difference when assembling a run of cabinet boxes or drawer components. The flat head carries milling nibs on the underside that cut a clean countersink as the screw seats, so the head ends up flush without pre-drilling a countersink hole. That keeps the assembly sequence short and the surface clean in finished interiors.

A Two-Bit Option for Mixed-Crew Work

The combination drive recess accepts both a #2 Phillips and a #2 square bit. For shops that standardize on square drive, the Robertson geometry holds the screw on a correctly sized bit for controlled one-handed placement. For crews running Phillips, the same screw works without a bit swap. The package includes a 2-inch drive bit so the first box is ready to run immediately. Cabinet shops, millwork teams, and finish carpenters who work across multiple crews or tool sets will find the flexibility useful on days when bit selection is not uniform across the site.
