A star knob is a manually operated fastening or adjustment control used to secure or position a component without the need for tools. On Bomag cold milling machines, star knobs are typically found on guards, covers, or adjustable assemblies where the operator needs quick, repeated access during setup or servicing. When a star knob cracks, strips, or becomes difficult to grip, it slows down adjustments and can compromise the secure positioning of the component it controls. Replacing a worn knob with a genuine Bomag unit restores smooth, tool-free operation and keeps machine adjustments fast and accurate on the job.
