The FastCap #10 x 3-inch flat head wood screw is built for wood assembly work that demands full reach into thick material. The Type 17 auger point, coarse thread, and nibs under the flat head make this screw a reliable choice wherever a deeper bite and a flush finish matter.
At 3 inches, this screw is sized for joints where shorter fasteners cannot get adequate thread engagement into the receiving member. Think cabinet carcass assemblies where panels stack thick, box-to-box connections in frameless cabinetry, or solid-wood joinery in furniture that needs a fastener with staying power across the full depth of the joint. The coarse thread works with the grain structure of softwood and engineered panels, pulling threads tight without the screw walking loose over time.
The Type 17 auger point carries a longitudinal flute that evacuates wood fiber ahead of the thread, reducing the torque needed to drive the screw through dense or layered material. That matters when driving a 3-inch fastener into a hard glue line or through a panel face into solid framing. The #2 square drive recess is designed to keep the bit engaged under that load. A correctly sized square bit seats into the recess with enough contact to transfer torque cleanly, which matters most on long screws where the driver is working hardest at full depth. The flat head with nibs finishes the job: the milling ridges cut a tidy countersink as the screw is driven, so the head ends up flush without prep work.
Cabinet shops assembling thick panel constructions, furniture builders joining solid-wood components, and finish carpenters fastening into layered substrate all reach for a 3-inch fastener when shorter screws would leave too little thread in the second member. The black finish suits interiors where visible fastener heads should recede rather than stand out, including dark cabinet interiors, painted MDF casework, and furniture built with a matte finish. This is an indoor wood assembly screw; it is not rated for exterior or treated-lumber applications.
The 3-inch length gives you more thread in the receiving member, which matters when you are driving into thick stock, through a face panel into solid framing, or across a glue-up where a shorter screw would not reach the second piece with enough thread for a secure grip.
The fluted tip on a Type 17 auger point removes wood fiber as the screw advances, which reduces driving resistance and the risk of splitting when the screw is traveling the full 3-inch depth through dense or laminated material.
The square recess is designed to hold a correctly sized bit securely, which helps maintain engagement when the driver is working hardest near the end of a long drive. Using a bit that is true to size is important to get that benefit.
This screw has a coarse thread, which is suited for softwood, plywood, and sheet goods. Coarse-thread screws are not recommended for hardwood face frames, where a fine-thread screw is the right choice to avoid splitting the stock.
No. This is an indoor wood assembly screw. For exterior or treated-lumber work, choose a fastener with a coating rated for outdoor exposure.
When the joint depth demands a fastener that goes the distance, this FastCap #10 x 3-inch black flat head screw combines the auger point, coarse thread, square drive, and nibs to drive cleanly, seat flush, and hold in solid wood and engineered panels.
