["Stainless steel material: 304 stainless steel precision forging for sidewalk bolts, inherently resistant to oxidation and corrosion. Long-lasting rust prevention in harsh environments, no oxidation or deformation, and maintaining the metallic luster and strength for a long time. Its lifespan is several times longer than that of ordinary iron screws. It is an ideal accessory for outdoor and high-frequency scenarios.","Wing-shaped design: The bed frame hardware features an original double-winged handle structure, modeled after the shape of an airplane wing, which increases the area for hand application of force. This enables a \"bare-handed twisting\" operation, allowing for quick locking and disassembly. It is particularly suitable for scenarios requiring frequent disassembly and assembly or for emergency situations without tools, being both efficient and effortless.","Complete set of gaskets included: Along with the hexagon bolts, thickened flat gaskets are provided. After installation, they effectively increase the contact area and distribute the locking pressure. Not only do they perfectly protect the surface of the workpiece from scratches, but also fill the installation gap, enhancing the anti-vibration and sealing performance. One set is fully equipped, ready for direct installation, eliminating the hassle of purchasing additional accessories.","Strong assembly stability: The bed frame bolts have strong and resilient screws that lock tightly, the gaskets provide buffer protection and shock absorption, and the wing-shaped nuts self-lock for secure tightening. The three forces work together to form a tight and stable connection structure, ensuring that the equipment and furniture remain firmly in place over a long period of time without shifting, and providing comprehensive protection for usage safety and structural durability.","Multifunctional fastening accessories: The wing-shaped nuts and bolts integrate functions of tightening, adjusting and fixing. They are widely used in photography equipment, 3D printers, small mechanical devices, computer cases and cabinets, bags and other items. They can be used as regular connecting parts or locking components for adjusting the equipment positions, and are versatile accessories for DIY craftsmanship and industrial assembly."]
