Description:

Good Material: The knurled nut is made entirely of plastic, with a smooth surface and corrosion and rust-resistant properties. The internal threads are made of copper core material, which is high in hardness and wear-resistant, with clear and deep threads, ensuring long-term use.
Through Hole Design: The knurled butterfly nut features a simple, compact thread design, making it less likely to deform or slip during rotation. The bolt passes completely through the tightening knob, allowing for free adjustment and extending from the top to provide ample adjustment range. The thickened nut head and knurled edge design facilitate smooth rotation, ensuring a safe and convenient installation.
Easy to Use: Our locknuts have a knurled surface, making them very easy to use. You can tighten them by hand without tools, which makes tightening, installation, and removal convenient and brings convenience to your project.
Wide Application: These round knob fasteners are widely used in the machinery industry for fastening industrial products or furniture, such as cabinets, toolboxes, machine tools, 3D printer platforms, and instruments.
