About this item

  • 【Create Strong Metal Threads】 – Small screws often pull out of particle board, plywood, or plastic. These M6x20mm threaded inserts install easily to provide a steel socket for M6 machine screws. Specifications: M6 internal thread, 6mm inner diameter, 20mm overall length – the longest M6 insert for maximum thread engagement in extra thick materials. Perfect for repairing stripped holes in heavy furniture, thick table tops, bed frames, workbenches, and heavy-duty boards – giving you a durable, reusable fastening point.
  • 【Hex Socket Drive – Anti-Loosening Under Vibration】 – The hex drive design allows maximum torque transfer with the included hex wrench. Unlike ordinary wood screws that work loose over time, these screw-in nuts stay locked in place – ideal for items subject to movement, like chair legs, tables, bed frames, and heavy-duty DIY projects.
  • 【Zinc Plated Carbon Steel – Reliable Corrosion Resistance】 – Made from high-quality zinc plated carbon steel, these furniture connector nuts offer good rust resistance under normal indoor use. Unlike brass or plastic inserts that can strip or crack, our threaded inserts maintain their strength and integrity for years.
  • 【Simple DIY Installation】 – ① Drill a 7mm (9/32") hole 2mm deeper than the insert length (22mm total depth); ② Thread the M6x20mm hex drive insert into the hole using the provided hex wrench; ③ Tighten until flush. The self-tapping external threads cut cleanly into wood, plastic, and soft metals (like aluminum). Saves time compared to hammer-in or push-in nuts – and you can remove/reuse as needed. Pro Tip: The 20mm length provides maximum thread grip, making it ideal for 22-27mm thick materials
  • 【Complete 20-Piece Kit】 – You get 20 threaded inserts (M6 internal thread / 6mm inner diameter × 20mm length) + 1 hex wrench. Enough quantity for multiple furniture repairs, woodworking projects, or keeping as spares. The box keeps your inserts organized and easy to find. A cost-effective solution for DIYers, woodworkers, and furniture assemblers.

Review the product description, intended application, dimensions, materials, compatibility information, and installation requirements before ordering. If you are uncertain, contact us with details about your project and the product you are considering.

Are your products suitable for outdoor use?

Some products are designed for exterior applications, while others are intended only for indoor or protected areas. Check the individual product page for information about weather resistance, moisture exposure, temperature limits, and suitable surfaces.

Can I use these products for structural repairs?
