M8 Bakelite Ball Knob with Copper Core — 25 mm, M8 x 14 mm internal thread Key benefits Built for durability: copper core with a bakelite coating combines strength and wear resistance for long service life in industrial use. High-temperature performance: designed for continuous operation up to 180 °C, suitable where heat-resistant components are required. Precise fit and control: 25 mm ball diameter and integrated copper nut provide a smooth, non-slip grip for accurate manual adjustments. Simple, tool-free installation: internal metric thread (M8 x 14 mm) allows you to mount the knob by hand — just screw it onto a standard M8 thread and tighten securely. Stable and ergonomic attachment: the integrated internal thread evenly distributes force for vibration-free fastening and comfortable handling. Specifications Ball diameter: 25 mm Internal thread: M8 x 14 mm (metric) Core material: copper nut/core Coating: bakelite Continuous operating temperature: up to 180 °C Installation: hand-tighten onto M8 male thread; no tools required Compatibility and function Fits any component or lever with a standard M8 male thread and up to 14 mm engagement. The copper core and internal thread ensure reliable torque transfer and a secure connection while the bakelite surface offers a smooth, anti-slip touch. Suitable where repeated manual adjustments, vibration resistance, and elevated temperature tolerance are needed. Typical applications Machine tool hand levers and adjustment knobs that require durable, heat-resistant controls during continuous operation. Valve handles and control levers in industrial ovens, furnaces, or hot-process equipment where parts are exposed to elevated temperatures. Packaging, assembly-line, and automation machinery where frequent manual adjustments and vibration resistance are important. Installation and care Install by hand: screw the knob onto the M8 male thread and tighten until secure. No tools required. Inspect threads periodically for wear or contamination; clean and re-tighten as needed to maintain a vibration-free connection. This M8 ball knob delivers a compact, reliable, heat-resistant solution for industrial controls and manual adjustments where a durable, easy-to-install knob is required.
