The Atlantic Hardware KD555NP-31 is an M6 connecting screw sized for material thicknesses from 1-3/16 to 1-9/16 inches, with a fine thread, underhead nibs, and a Nickel finish. It is designed for furniture and cabinet assembly applications where the joint pulls tight, the head seats cleanly, and the finish matches the hardware around it.
Connecting screws like the KD555NP-31 are the fastener of choice for butt joints in cabinet carcasses, flat-pack furniture, bookcases, wardrobes, and similar panel-based assemblies. The screw threads into a pre-bored hole from one panel face and draws the mating panel tight against it, creating a joint that resists racking without glue or additional hardware. The 8 mm drill hole diameter is a standard confirmat-style bore, so the screw works with existing step-drill tooling already common in cabinet shops. The 1-3/16 to 1-9/16 inch material thickness range covers the combined stack of two standard 3/4-inch panels as well as slightly thicker or thinner engineered wood components.
The Nickel finish on the KD555NP-31 is a practical specification choice when the rest of the installation uses Nickel-finished hinges, drawer slides, or pulls. Exposed connecting screws on cabinet interiors and furniture backs are visible during installation and sometimes after, so a finish that matches the surrounding hardware gives the completed cabinet a cleaner, more intentional look. The fine thread engages the pre-bored panel material consistently without stripping, and the underhead nibs clean up the countersink seat as the head comes down, reducing the need for a separate head-countersink step.
Cabinet shops assembling carcasses with confirmat-style joinery are the primary users. The 100-piece box suits a production run of several cabinets or a full kitchen install without requiring bulk-pallet quantities. Furniture assemblers and millwork installers working with European-style panel joinery will also find the M6 thread and 8 mm bore a natural fit for their existing drilling and assembly setups. When the hardware spec calls for Nickel throughout, this screw keeps the fastener finish consistent from hinge cup to panel joint.
The KD555NP-31 requires an 8 mm drill hole. Use a step-drill or confirmat-style boring bit sized to 8 mm for the shank hole, with the head countersink matched to the screw head diameter.
Yes. Connecting screws with fine threads are used in particleboard, MDF, plywood, and melamine-faced panels. They are the standard fastener type for European-style carcass joinery in engineered wood.
The underhead nibs mill the countersink area as the screw seats, helping the head sit flush without requiring a separate countersink drilling step. They also resist the head spinning back if the driver slips.
Connecting screws can be backed out and re-driven for disassembly and reassembly, which is one reason they are specified for furniture that may need to be moved. Repeated removal and reinstallation will eventually reduce holding power in engineered wood panels.
The KD555 family is available in multiple finishes. Check the family listing to find the finish that matches your hardware specification.
When every fastener in the cabinet matches the hardware finish, the KD555NP-31 is the connecting screw that closes that loop, combining a standard M6 confirmat-style fit with a Nickel finish that coordinates with the rest of the installation.
