30 Pièces Inserts Filetés pour Bois, Écrous Inserts en Alliage de Zinc M4 x 10mm, Tête à Entraînement Hexagonal pour Meubles, Armoires et Projets de Menuiserie DIY

【Precise Installation】Easily create durable metal threaded holes in wooden components, providing reliable connection points that can be repeatedly assembled and disassembled for furniture, cabinets and other wood products. 【Strengthening Strength】Made of zinc alloy by high pressure casting, the outer wall has spiral grooves combined with barb structure. After implantation, the pulling force is 60% higher than ordinary straight groove inserts, ensuring they never turn or loosen in the wood fibers. 【Practical Solution】 When the solid wood furniture you make requires concealed screw fixing, or when repairing threaded holes on old wooden works that have become stripped, these inserts can quickly restore or even improve the strength of the connection. 【Simple Operation】Just use the corresponding hex key to screw them into the pre-drilled hole. The operation is as simple as tightening a screw. It is recommended to purchase several batches according to the number of furniture connection points and complete the installation kit. 【Smart Fusion】 When the screws fit perfectly with metal threads nestled in the heart of the wood, these small zinc alloy pieces are a testament to the clever fusion of traditional craftsmanship and modern durability.
