The Quickscrews #8 x 1-1/4-inch Flat Head Assembly Screw is a coarse-thread, lubricated wood assembly screw with a combo Phillips/square drive, underhead nibs, and a double auger point. The 1-1/4-inch length is a natural fit for joining 3/4-inch panels, cabinet components, and face-frame parts where a flush, clean-seated fastener is the goal.
Cabinet and casework assembly constantly calls for a screw that passes through one 3/4-inch layer and bites firmly into the next without punching through the back face. At 1-1/4 inches, this screw sits right in that window. It works for panel-to-panel butt joints, attaching wood drawer box sides, fastening cabinet backs into rabbets, securing light shelf cleats, and anywhere you are joining two layers of standard-thickness sheet goods. The coarse thread generates solid pull-out resistance in the softwood, plywood, MDF, and particleboard that makes up most cabinet carcasses, so the joint pulls tight and stays that way.
The combo drive recess accepts both a #2 Phillips and a #2 square bit, which means you are not stopping to swap bits when the driver on the bench is set up differently than the one in your hand. The double auger point has two opposing flutes that evacuate chips from the hole as the screw advances, helping it start cleanly in denser material and reducing the splitting pressure that a plain sharp point can create near an edge. Once the head arrives at the surface, the underhead nibs cut their own shallow countersink so the flat head sits flush without a separate boring step. The lubricated finish keeps driving torque low across the whole run, which matters when you are seating a box of 1,000 screws in a production day.
Cabinet shops building standard 3/4-inch carcasses in plywood or MDF will go through this size consistently. Furniture makers assembling drawer boxes and small cabinet components reach for the 1-1/4-inch length because it threads through face stock and bites without breaking through the opposite face. Trim carpenters attaching blocking, cleats, and light structural pieces to 3/4-inch substrates find that the coarse thread and double auger point make fast work of both softwood and composites. For interior wood assembly — not outdoor or pressure-treated applications — this is a reliable everyday screw in a pack size that keeps a production operation stocked.
The recess is designed to accept a #2 square bit for one-handed placement when the bit fits correctly. A correctly sized #2 square bit seats in the recess and holds the screw on the bit; a worn or off-spec bit may not grip as reliably. The same recess also accepts a standard #2 Phillips bit.
A standard Type 17 point has one flute that clears chips as the screw enters. The double auger point adds a second opposing flute, which doubles the chip-clearing capacity and helps the screw start and advance faster in denser or thicker wood.
In most wood and panel materials, the underhead nibs mill their own countersink as the head seats, so a separate countersink step is often unnecessary. In very hard or dense stock, pre-countersinking can still help the head seat cleanly.
No. This is an interior assembly screw. For outdoor or pressure-treated applications, use a screw with a coating rated for ACQ or exterior exposure.
Coarse thread provides strong pull-out resistance in softwood, plywood, MDF, and particleboard. For hardwood face frames, a fine-thread screw is generally the better choice to prevent splitting.
When 3/4-inch panels are the building block, the 1-1/4-inch length covers the joint without guesswork — and with a lubricated finish, combo drive, and double auger point, this screw is built to keep a production run moving from the first box to the last.
