These M8x20mm threaded inserts install easily to provide a steel socket for M8 machine screws. Specifications: M8 internal thread, 8mm inner diameter, 20mm overall length – the longest and strongest M8 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.\u003c\/li\u003e\n\u003cli\u003e【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.\u003c\/li\u003e\n\u003cli\u003e【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.\u003c\/li\u003e\n\u003cli\u003e【Simple DIY Installation】 – ① Drill a 9mm (11\/32\") hole 2mm deeper than the insert length (22mm total depth); ② Thread the M8x20mm 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).
