Atlantic Hardware M6-1-7/16 - 1-7/8" - Fine Thread Nickel, 555NP-37 - 500/Box

Atlantic Hardware M6 Connection Screw For Joinery

Atlantic Hardware M6 connection screw gives you a fine thread nickel fastener for joining components where a reliable metal thread is needed. The screw uses an M6 fine thread, so it engages cleanly in compatible metal threads and helps produce a tighter fit in the joint. The threaded section is a galvanized steel bolt, which provides corrosion resistant steel in the load-bearing part of the fastener and supports service in typical shop or installation environments. The head of the screw is plastic, so it bears directly against a plastic socket and helps distribute clamping force over the insert face. The matching plastic insert has a plastic socket that receives the screw head, which creates a metal-through-plastic connection between the parts being joined. The insert is ribbed to prevent rotation while tightening, so torque is transmitted into clamping instead of spinning the insert in the material.

Key Connection Screw Details For Daily Work

• The M6 fine thread on the galvanized steel threaded bolt provides a precise metal thread engagement, which supports repeatable tightening torque in each joint.
• The corrosion resistant steel construction in the threaded bolt maintains its function in normal woodworking and cabinet environments, which supports consistent performance over time.
• The plastic insert with a plastic socket and screw head creates a metal-to-plastic interface, which helps spread load over the insert and supports joints in lighter construction materials.
• The ribbed design on the plastic insert prevents rotation while tightening, which keeps the insert seated in the material so the clamp force builds in the joint instead of spinning.
• Each set consisting of one male and one female component forms a complete connection point, which lets you plan joints around a known pair of mating parts.
• Standard boxes of 100 sets and additional bulk pack options support project-level purchasing, which suits production runs or stocking for repeated assemblies.

Installation Behavior Of The M6 Fine Thread Screw

The M6 fine thread on this connection screw engages gradually, which helps the galvanized steel threaded bolt draw the joint together in a controlled way during tightening. The ribbed plastic insert is designed to stay fixed in its bore during tightening, so torque applied at the plastic screw head is directed into clamping rather than spinning the insert. The plastic socket and matching plastic screw head mate together, which allows the metal bolt to load the joint while the plastic components interface with the workpiece surface. The connection screw length range of 1-7/16 to 1-7/8 inch defines the clamping span, so the fastener can bridge components within that material thickness range.

Using The 555NP-37 Connection Screw In Assemblies

Where This Atlantic Hardware M6 Screw Fits Best

This Atlantic Hardware M6 connection screw is specified with a 1-7/16 to 1-7/8 inch connection length, which suits joints where the combined thickness of the parts falls within that span. The galvanized steel threaded bolt runs through the joint, while the plastic insert with its plastic socket seats in one component and receives the plastic screw head from the opposite side. Because the insert is ribbed to prevent rotation while tightening, it supports use in materials where pull-out resistance depends on surface engagement rather than internal threads. The corrosion resistant steel bolt carries the tensile load, so the screw can serve in typical cabinet, fixture, or furniture-type assemblies that rely on a metal tension member and a plastic locating insert.

Why These Screw Details Support Repeatable Results

The fine thread nickel M6 design on the 555NP-37 connection screw provides a consistent pitch, which helps installers achieve similar clamp force from one joint to the next with a familiar turning feel. The galvanized steel threaded bolt concentrates strength in the core of the fastener, so the joint depends on a metal load path even though the interface at the work surface is plastic. The ribbed plastic insert resists spinning during tightening, which maintains alignment of the connection point in the predrilled bore across multiple assemblies. With each set providing a defined male and female pair, the installer works with a predictable interface on both sides of the joint, which supports faster layout and reduced rework on repetitive builds.

Common Questions About The 555NP-37 Connection Screw

Selecting The 555NP-37 For Your Next Assembly Run

The Atlantic Hardware M6 connection screw 555NP-37 combines an M6 fine thread, a galvanized steel threaded bolt, and a ribbed plastic insert with a plastic socket and screw head to form a defined male and female joint. The 1-7/16 to 1-7/8 inch connection range suits assemblies built around that material thickness span, while standard boxes of 100 sets and bulk options match well with production or repeat build environments. For work that benefits from a metal tension member paired with a locating plastic insert, this connection screw provides a consistent, repeatable fastener format.
