Atlantic Hardware M6-1-7/16 - 1-7/8" - Fine Thread Nickel, KD555NP-37 - 100/Box

Long-Reach Connecting Screw For Thick Panel and Flat-Pack Assembly

The Atlantic Hardware M6 KD555NP-37 is a fine-thread connecting screw sized for material thicknesses from 1-7/16 to 1-7/8 inches. Finished in Nickel and packed 100 to the box, it is built for furniture assembly, cabinet carcass construction, and flat-pack joinery where thicker combined panel sections require a longer-reach fastener.

Key Features

• Fits 1-7/16 to 1-7/8 inch combined material thickness, making it the right reach for thicker panel assemblies in this connecting screw family.
• M6 fine thread provides consistent thread engagement in pre-bored holes across hardwood, particleboard, MDF, and melamine panels.
• 8 mm drill hole diameter matches the standard bore size for KD-style connecting hardware.
• Underhead nibs help the head seat cleanly and resist rotation once the screw is driven to final position.
• Nickel finish blends with chrome and satin-metal hardware fittings common in contemporary cabinet and furniture work.
• 100 screws per box suits both single-project needs and ongoing production use.

Where This Screw Fits the Job

Connecting screws span a range of material thicknesses, and matching the screw to the actual combined panel depth is the critical variable. This variant handles the thicker end of the range, at 1-7/16 to 1-7/8 inches, which comes up when joining two full-thickness panels, when a panel face meets a thicker substrate, or when the assembly design stacks multiple layers before the fastener seats. Flat-pack furniture, RTA cabinet carcasses, wardrobe boxes, and bookcases built from 3/4-inch or thicker engineered panels are the natural home for this screw. The 8 mm bore requirement is consistent with KD-style cam-lock and barrel-nut hardware, so this screw works alongside the fittings already specified for those systems.

Nickel Finish in a Working Hardware Context

The Nickel finish is a practical choice in cabinet and furniture interiors where exposed fastener heads are visible at joints or in accessible compartments. Nickel reads as a clean, neutral metal tone that pairs well with the brushed and satin hardware finishes widely used in contemporary kitchens, baths, and office furniture. The finish also reduces the visual contrast between the screw head and light-colored panel surfaces or metal cam-lock hardware surrounds. For production shops assembling furniture with mixed visible and concealed hardware, having the connecting screw finish coordinate with other fittings is a detail that holds up in the finished piece.

Who Reaches for This Box

Cabinet shops and furniture manufacturers who build with thicker engineered panels will find this screw handles the combined panel depths that shorter variants in this family do not reach. RTA product builders specifying KD hardware systems need the correct screw length to match each joint's total material stack, and this variant covers the thicker assemblies in that range. Installers completing flat-pack furniture on site benefit from having the right screw for the job rather than substituting a length that seats proud or bottoms out before the joint closes. The 100-piece box works for a single large assembly run or as restocking inventory for a shop that moves through connecting screws regularly.

Common Questions

The Right Screw for Thicker Panel Joints

When the assembly calls for a connecting screw with the reach to close a joint through 1-7/16 to 1-7/8 inches of combined material, this M6 fine-thread Nickel screw from Atlantic Hardware does the job cleanly and finishes in a tone that holds up in visible hardware applications.
