This Würth #8 x 1-1/4 inch flat head assembly screw is sized for joining 3/4-inch panels and cabinet components where a screw that fully engages the receiving piece without over-penetrating is the priority. It pairs a Type 17 Auger point with coarse thread, a #2 square drive, milling nibs under the flat head, and a zinc finish in a 5000-piece pail suited to production shop use.
At 1-1/4 inches, this screw is a natural match for face-to-panel attachments where the receiving member is 3/4-inch thick. It threads fully into the receiving piece with enough bite to pull the joint tight without the tip emerging on the finished face. Cabinet box assembly, stretcher-to-side connections, and drawer-box construction in 1/2-inch to 5/8-inch material with a 3/4-inch back panel all fall into the range this length handles cleanly. Production shops building frameless or face-frame cabinets in volume will reach for this length repeatedly across a single run.
The Type 17 Auger point uses an extended flute to pull wood fibers out of the hole as the screw is driven, keeping driving torque low and reducing the risk of splitting at tight margins. The coarse thread is the right choice for the engineered panels, plywood, and softwood species that make up most cabinet carcass work — it grips the fiber matrix quickly and resists withdrawal under racking loads. When the screw reaches full depth, the milling nibs under the flat head cut a clean countersink seat so the head finishes flush without a separate boring step.
The 5000-piece pail format keeps this screw accessible at the bench or at the point of install without constant restocking. Pail packaging is convenient for movement around the shop or to the job site. The zinc finish suits the indoor cabinetry environment this screw is designed for. The #2 square drive is compatible with the driver bits already in rotation in most cabinet shops, and its geometry is designed to hold the screw on a correctly sized bit for one-handed placement — a measurable time-saver when you are driving dozens of connections per assembly.
The screw needs enough length to pass through the first member and thread deeply into the second. At 1-1/4 inches, there is enough shank engagement in the receiving 3/4-inch piece to develop full withdrawal resistance without the tip breaking through the opposite face of the panel.
Coarse thread is optimized for softwood, plywood, MDF, particleboard, and melamine — the engineered sheet goods and softwoods most cabinet carcasses are built from. Fine thread is the correct choice for hardwood face frames; this screw's coarse thread is for the panel and box work.
In most cabinet panel materials, no. The milling nibs under the flat head cut the countersink as the screw seats. In very hard or dense materials a pilot countersink can help, but in plywood, MDF, and particleboard the nibs handle it in one step.
Yes. Square drive and Robertson refer to the same four-sided socket geometry. A #2 square bit fits this screw. The square recess is designed to hold the screw on a correctly sized bit, which aids one-handed placement when driving into assembled cabinet components.
No. The zinc finish on this screw is rated for dry indoor environments. For exterior or pressure-treated lumber applications, choose a screw with a coating rated for outdoor exposure.
When the work is cabinet and panel assembly in 3/4-inch material and the volume calls for a pail rather than a box, this Würth #8 x 1-1/4 inch assembly screw covers the length, thread, point, and drive combination that keeps a shop moving through a full production run.
