The Würth #8 x 1-1/4-inch flat head assembly screw is a coarse-thread, sharp-point fastener built for cabinet box assembly, drawer construction, and general panel joinery in 3/4-inch material. A lubricated finish reduces driving torque, and the combination drive recess accepts either a #2 Phillips or a #2 square bit, giving production shops and installers flexibility with the bits already on hand.
At 1-1/4 inches, this screw is sized for fastening through a single layer of 3/4-inch material and threading into a second panel or substrate behind it. That makes it a natural fit for cabinet box assembly, where sides, tops, and bottoms meet at butt joints, and for attaching drawer box components in plywood or Baltic birch. It also works well for securing cabinet backs, installing shelf cleats, and other shop tasks where the fastener needs enough bite in the second member without punching through the back face of thinner panels. For thicker stacks or longer penetration depths, other lengths in this family cover those applications.
The combination Phillips/square recess in this screw means one box works with whichever bit style is loaded in the driver. The square recess is designed to hold the screw on a correctly sized bit for steadier one-handed placement. The Phillips side keeps the screw compatible with the most common bit type on the job site. Neither drive requires a dedicated bit change between tasks. The lubricated coating on the screw body is a dry-touch finish that reduces friction as the threads cut through wood fibers, lowering the torque needed to seat the head flush. In a production cabinet shop running hundreds of joints per day, that reduction in driving resistance adds up and helps reduce fatigue and bit wear over a full shift.
This screw is a workhorse for cabinet manufacturers, millwork shops, and finish carpenters who run high volumes of box and panel assembly. The coarse thread and sharp point work reliably in softwood plywood, cabinet-grade birch, MDF, and similar engineered panels. The flat head countersinks cleanly in these materials, leaving a surface ready for edge tape, paint, or a finished interior without additional work. The box of 1,000 is practical for shops that go through fasteners quickly and want a consistent screw across all their box-building without switching between products mid-run. It is an indoor assembly fastener suited to dry shop and installation environments.
Yes. The combination recess accepts a standard #2 Phillips bit. The square recess is also available in the same head if you prefer to use a #2 square bit.
The lubricant is a dry-touch coating applied to reduce driving friction. It is intended for hidden or interior fastening applications and is not formulated to be glue-compatible. If glue joints run directly over fastener locations, use a screw without a lubricated finish in those spots.
No. This is an interior assembly screw. For outdoor or high-humidity applications, choose a screw with a corrosion-resistant coating rated for the exposure level.
It can be used in MDF and particleboard for light cabinet assembly, but coarse-thread screws provide less pull-out resistance in those materials than in plywood or solid wood. Pre-drilling near edges helps prevent surface blowout in engineered panels.
It uses a flat (countersunk) head. For a flush finish, the receiving panel should be countersunk to match the head angle. In softer plywood and many cabinet panels, the sharp point and head profile will self-countersink under normal driving torque.
A screw that drives smoothly, seats flush, and works with the bits already in the driver keeps assembly moving without interruption. The Würth #8 x 1-1/4-inch combo drive assembly screw delivers that consistency across the cabinet box work and panel joinery where shops need it most.
