The Kreg #8 x 1" Washer Head Face Frame and Pocket-Hole Screw is sized for softwood and engineered panel joinery in 3/4-inch stock. The 1-inch length keeps the tip well within the joint without breaking through the far face, making it a natural fit for cabinet box assembly, face frame attachment, and similar work where stock thickness and screw length need to match precisely.
At 1 inch, this screw is calibrated for 3/4-inch stock, the standard thickness for cabinet boxes, plywood panels, and most face frame material in residential and light commercial work. Driving a longer screw into thin stock risks the tip breaking through the far face or the panel edge. This length stays safely within the joint, which matters especially when pocket holes land near the edge of a narrow stile or a thin panel side. It is also a common length for attaching a face frame to a cabinet box, where the screw passes through the face frame and bites into the box panel without over-penetrating.
Coarse thread is the correct choice for softwoods like pine and poplar, as well as sheet goods including plywood, MDF, and particleboard. The wider thread spacing bites more material per revolution and generates higher pull-out resistance in low- to medium-density substrates than a fine thread would. The zinc finish suits the controlled indoor environments where cabinet and furniture assembly happens. These screws are for dry, interior work.
Five hundred screws is a working quantity for a production cabinet shop running softwood face frames or assembling plywood cabinet boxes in volume. For a remodeler or installer, the same box covers a full kitchen or bath install without the waste of a larger bulk container. The washer head and square drive combination is standard across the Kreg pocket-hole screw line, so the same bit and driver setup works throughout a job.
When two pieces of 3/4-inch stock meet face to face, the total thickness at the joint is 1-1/2 inches. A 1-inch screw is sized for a single layer of 3/4-inch stock, not for stacked thickness. For face-to-face joints or thicker assemblies, a longer length is the better choice.
Coarse thread is designed for softwood and sheet goods like plywood, MDF, and particleboard. The wider thread spacing digs into the fiber matrix of those materials and holds well. Fine thread is the right call for hardwood face frames in maple, oak, or cherry, where the tighter grain needs a different engagement pattern to avoid splitting.
The Type 17 auger point has a flute near the tip that cuts and removes wood fibers as the screw drives. That chip-clearing action reduces the torque needed to seat the screw and lowers splitting pressure at the joint, which is useful when pocket holes land close to a material edge.
Yes. The 1-inch length, washer head, and coarse thread make this a practical choice for attaching a softwood or plywood face frame to a cabinet box side where 3/4-inch stock is involved. The washer head distributes clamping force across the pocket wall and the coarse thread grips the panel without splitting it.
This screw uses a coarse thread, which is suited to softwood, plywood, and engineered panels. For hardwood face frames in maple, oak, or similar dense species, a fine-thread pocket-hole screw is the better match. Coarse thread in tight-grained hardwood can split the stile under torque.
When the job calls for pocket-hole or face frame joinery in 3/4-inch softwood or sheet goods, this Kreg SML-C1 screw delivers the length, thread, point, and head geometry that match the work without over-engineering the fastener.
