Material: The socket head nut is made of color galvanized carbon steel, offering high hardness, resistance to deformation, corrosion resistance, good fastening effect, and easy screwing. Features: The nut has high strength and impact resistance, and is more stable when connecting to wooden furniture, effectively preventing loosening and ensuring a secure hold for a long time. Overall size: 8 different screw sizes: M4*10mm*80, M5*10mm*60, M6*10mm*30, M6*15mm*20, M6*17mm*20, M6*20mm*9, M8*20mm*5, M8*25mm*6 (inner diameter*length*quantity). Safety tips: Apply wood glue to the hole (on the side wall), insert and turn the nut several times, apply glue to the nut's threads, then tighten the nut completely so that it is flush with the wood. The wood should be flat and as dry as possible.
