Six-Lobe Star Through-Hole Hand Knob Tightening Fastener with Brass Internal Thread for Furniture Decoration, Food Industry, Marine Parts, Mechanical Operations and General Industrial Production
Product Description
This six-lobe star through-hole hand knob fastener combines a black hard plastic exterior with an embedded brass internal thread, delivering a practical balance of grip comfort and reliable fastening strength. The six-petal plum blossom shape provides an ergonomic surface that allows easy manual tightening and loosening without additional tools, making it a convenient choice for frequent adjustments. Available in M4 and M5 internal thread specifications, both sizes share consistent parameters: an overall height of 11.3mm, an overall diameter of 24.5mm, a top diameter of 12.6mm, and a central boss height of 4mm. This compact yet sturdy design allows the knob to work seamlessly with screws, bolts, and nuts across a wide range of applications. Whether you are assembling furniture, maintaining marine components, operating machinery, or managing routine industrial production lines, this hand knob offers dependable performance. The brass internal thread resists wear from repeated use, while the black plastic body keeps the overall weight low and comfortable to handle. In food industry environments, the smooth surface is easy to wipe clean, supporting hygienic working conditions. For mechanical operations, the star-shaped profile gives users a firm grip even in tight spaces. Every cloud has a silver lining — and for anyone tired of fumbling with loose nuts and bolts, this hand knob is exactly that silver lining, simplifying adjustments and reducing downtime. Its neutral black and brass color scheme blends well with most equipment and furniture styles, making it a versatile addition to workshops, production floors, boats, and home projects alike.
