An internally threaded insert for wood (stainless steel) is used to create a strong, durable metal thread inside wood, allowing machine screws or bolts to be installed and removed repeatedly without damaging the wood.

Common applications include:

• Furniture assembly – Beds, tables, chairs, desks, and cabinets that need to be assembled and disassembled multiple times.
• Knock-down furniture – Flat-pack or modular furniture where strong threaded connections are required.
• Marine applications – Boats, docks, and outdoor furniture where stainless steel provides excellent corrosion resistance.
• Outdoor projects – Pergolas, decking, garden furniture, and timber structures exposed to the weather.
• Woodworking jigs and fixtures – Creating reusable threaded mounting points in workbenches, router tables, and shop fixtures.
• Mounting hardware – Attaching handles, hinges, brackets, machine components, or equipment to wood using machine screws.
• Musical instruments – Securing necks, pickguards, or hardware where repeated removal is expected.
• 3D printer and CNC projects – Reinforcing wooden frames or enclosures with durable threaded connections.
• Repairing stripped wood threads – Restoring damaged screw holes with a stronger metal thread.
• Heavy-duty fastening – Providing higher pull-out strength than wood screws alone in hardwoods and softwoods.

Benefits of stainless steel inserts

• Corrosion and rust resistant.
• Suitable for indoor, outdoor, and marine environments.
• Stronger and more wear-resistant than threading directly into wood.
• Allows repeated installation and removal of machine screws without degrading the wood.

Compatible materials

They can be installed in:

• Hardwood
• Softwood
• Plywood
• MDF (with appropriate sizing)
• Particleboard (light to moderate loads)

These inserts are typically used with machine screws, socket head cap screws, button head screws, countersunk screws, or hex bolts that match the insert's internal thread (e.g., M4, M5, M6, M8, 1/4"-20, etc.).
