Product Summary
This M6 Insert Nut is a yellow zinc plated carbon steel fitting used to create a machine-threaded fixing point inside wood. It is designed for furniture production, wood panel joining, repair hardware packs, and knock-down furniture assembly.
After the insert is driven into a prepared hole, an M6 bolt or machine screw can be tightened into the internal thread. This gives the furniture part a reusable metal thread instead of relying only on direct screw holding in wood.
The product is mainly selected for wood applications that need a stronger and cleaner fastening point, such as pine boards, plywood panels, fiberboard, solid wood parts, and furniture combination systems.

Why This Insert Is Used
Wood may loosen after repeated screw installation, especially in flat-pack furniture or repair parts. This M6 insert nut solves that problem by placing a metal thread inside the wood.
For production buyers, it helps keep assembly more consistent. For furniture repair kit suppliers, it provides a standard replacement part that can be packed with bolts, washers, or other hardware. For cabinet and furniture factories, it works as a practical connector for repeated tightening points.
Material and Finish Advantages
The carbon steel body gives the insert good hardness and wear resistance during installation. Yellow zinc plating provides a clean yellow-gold surface and basic protection for indoor furniture hardware.
The finish also makes the part easy to identify in hardware kits, which is useful for assembly packs, repair kits, and mixed furniture fastener sets.
Hex Socket Installation
The standard hex socket head allows the insert to be installed with an internal hex wrench or matching drive tool. This is convenient for furniture workshops, assembly lines, and repair kit users.
The flanged thread texture helps the insert bite into the wood and reduce unwanted rotation after installation. The burr-free surface also helps the insert enter the pilot hole more smoothly.
Installation Notes
Drill a pilot hole before inserting the nut. The hole depth should normally be 1–2 mm deeper than the insert body length.
For pine, plywood, or fiberboard, use a hole size that allows the outer thread to grip the material firmly. For dense solid wood or harder boards, the hole may need to be slightly larger to reduce driving force and avoid cracking.
Once the insert is fixed in place, install the matching M6 bolt or machine screw into the internal thread.

Supply and Packing
This M6 insert nut can be supplied for bulk furniture production or packed as part of hardware kits. Packing can be arranged by quantity per bag, mixed kit requirement, barcode label, private label, or export carton.
For buyers who need matched accessories, bolts or screws can also be quoted together according to the assembly requirement.
FAQ
Q1: What is the main difference between this product and a normal wood screw?
A wood screw cuts directly into the wood. This insert nut creates a metal M6 thread inside the wood, so the matching bolt can be tightened, removed, and reinstalled more reliably.
Q2: Why is yellow zinc plating used?
Yellow zinc plating gives the carbon steel insert a clean surface and basic rust protection for indoor furniture hardware. It is also easy to identify in mixed hardware kits.
Q3: Can it be installed in plywood?
Yes. Plywood, pine, fiberboard, and solid wood are common application materials. The pilot hole size should be adjusted according to the material density.
Q4: What should be checked before bulk ordering?
Please confirm the insert length, outside diameter, pilot hole requirement, matching bolt size, packing quantity, and whether the product will be used in soft wood or hard wood.
Q5: Can this item be packed with bolts?
Yes. It can be supplied as a single insert nut or packed together with matching M6 bolts, washers, or other furniture hardware parts.
