The Quickscrews #8 x 1-1/4-inch flat head assembly screw is a coarse-thread wood screw built for cabinet boxes, face frames, and general woodworking joinery where the fastener needs to disappear into the surface. A #2 square drive, Type 17 auger point, and underhead nibs make this screw well suited to the high-repetition work that fills a cabinet shop's day.
At 1-1/4 inches, this screw is sized for common cabinet assembly joints: fastening a 3/4-inch panel face to a second panel edge, securing cabinet backs in rabbets, attaching hanging rails to cabinet sides, and similar two-member joints in 3/4-inch material. The length reaches well into the second member for solid pull-out resistance without punching through the back face of a single panel. For shops running standard 3/4-inch sheet goods, this is often the go-to length for interior box assembly.
The square drive recess grips a correctly sized #2 square bit cleanly, which matters when the same screw is being driven hundreds of times in a shift. The Type 17 auger point carries a flute that cuts a channel through wood fiber ahead of the thread, which lowers the torque needed to start and reduces the risk of splitting near edges or in thin stock. Once the screw is near flush, the nibs on the underside of the flat head mill away the surrounding material so the head seats cleanly without a countersink bit. These three features work in sequence: the point starts fast, the thread drives with less resistance, and the head finishes flush.
This screw is at home in cabinet shops producing frameless or face-frame cabinets in softwood, plywood, MDF, or particleboard. The zinc finish is suited for dry indoor environments: cabinet boxes, drawer components, interior panel assemblies, and similar work where moisture is not a factor. Shops that need a reliable coarse-thread flat head in the 1-1/4-inch length, in large enough quantity to keep a station stocked, will find this box format practical for both bench work and production lines. It is not the right screw for outdoor exposure or pressure-treated lumber.
A 1-1/4-inch screw passes through a 3/4-inch face or rail and seats roughly 1/2 inch into the second member, which is enough thread engagement for a solid joint without risk of breakthrough in most panel assemblies.
The Type 17 point has a longitudinal flute near the tip that removes wood fibers as the screw enters the material. This chip-clearing action lowers driving torque and reduces splitting compared to a plain sharp point, especially near panel edges.
In most softwood and sheet-good substrates, yes: the nibs mill the countersink as the head seats, so a separate countersink step is often not needed. Results can vary in very dense hardwood or thin laminate faces.
No. The zinc finish is rated for dry indoor use. Outdoor and pressure-treated applications require a corrosion-resistant coating compatible with ACQ chemistry.
The square recess accepts a #2 square drive bit. Using a correctly sized bit is important for the bit-retention feature to function as intended.
When the job calls for a flush-seating, fast-starting assembly screw in a length matched to 3/4-inch cabinet material, this Quickscrews flat head delivers the drive engagement, point geometry, and pack size to keep production moving without interruption.
