This Quickscrews #8 x 2-1/2" flat head assembly screw is built for wood-to-wood fastening where extra length is the priority. A combination square/Phillips drive, coarse thread, milling nibs, double auger point, and lubricated finish work together to make this screw a reliable choice for cabinet carcass assembly, face-frame attachment to box sides, thick solid-wood joinery, and other applications where 2-1/2 inches of penetration is what the joint calls for.
A 2-1/2" screw is the right call when the joint demands reach. Attaching a face frame to a cabinet box built from 3/4" material, the screw passes through the frame and buries deep into the box side for a connection that holds under racking and door-swing loads. In solid-wood panel builds, carcase assembly with two layers of 3/4" stock, or any situation where a shorter screw would leave too little thread in the second member, this length closes the gap. The coarse thread grabs well in softwood, pine, poplar, plywood, and MDF, making it a practical choice across the mix of materials a cabinet shop runs on any given day.
The double auger point carries two opposing flutes that clear chips quickly as the screw enters thick stock, reducing the torque spike that can stall a driver or split a workpiece. In dense material or when driving close to an edge, that chip clearance matters more as screw length increases. The flat head's milling nibs relieve wood fibers under the head as the screw seats, helping the head pull flush cleanly without tearing or mushrooming the surface. The combination square/Phillips recess means the screw works with either drive type. The square recess is designed to hold the screw on a correctly sized bit for one-handed placement, which matters when reaching into a cabinet box or working in tight assembly positions.
Cabinet shops and millwork teams running high volumes need screws that keep up. The lubricated finish lowers driving resistance so each screw seats with consistent torque, reducing the fatigue that builds through a long assembly run and decreasing the chance of over-driving in softer panels. Packed 500 to the box, this screw suits shops that go through fasteners in quantity and want a box that lasts through a meaningful stretch of production rather than running out mid-job.
The 2-1/2" length is the right choice when the joint requires deep thread engagement in the receiving member. Typical scenarios include attaching a 3/4" face frame to a cabinet box where you want at least 1-1/2" of thread in the box side, or assembling two layers of 3/4" material where a shorter screw would not reach far enough into the second piece.
A standard Type 17 point has one flute that clears chips as the screw enters the material. The double auger point has two opposing flutes, which doubles the chip-clearing capacity. This is most useful in thick, dense, or resinous wood where a single flute can pack and slow the screw down before it reaches full depth.
Yes. The combination recess accepts both a #2 Phillips and a #2 square bit. Either will drive the screw; the square recess generally offers better cam-out resistance and is designed to hold the screw on a correctly sized square bit, while Phillips works with the drivers most installers already carry.
You can countersink separately, and in very hard or figured wood that is sometimes the cleaner approach. In softwoods, plywood, MDF, and most cabinet-grade panels, the nibs mill their own countersink as the head seats, saving the extra step. Either workflow produces a flush result.
No. This screw carries a lubricated finish designed for indoor woodworking and cabinet assembly. It is not rated for exterior or high-moisture environments.
When 3/4" stock and a face frame meet, or when two thick members need a connection that holds under load, this 2-1/2" assembly screw has the length, point geometry, and drive versatility to get the joint done cleanly and keep the assembly line moving.
