Key Features
- Genuine OEM Construction — manufactured by Bomag to the exact material grade and dimensional tolerances of the original star knob, maintaining consistent grip and thread engagement over time
- Direct Drop-In Installation — threaded interface matches the original mounting point exactly, allowing this star knob to seat and torque down without rework or modification
- Broad Fleet Coverage — fits BW-series single drum rollers including BW 145 D-3, BW 177 D-3, BW 213 D-3, and BW 216 D-3; tandem rollers including BW 161 AD-2, BW 174 AD, and BW 202 AD-2; BC-series refuse, landfill, and soil compactors; BM-series cold milling machines including BM 500/15 and BM 2000/75; and MPH/RS-series recycler/stabilizers including MPH 125, MPH 600, and RS 650
- Ergonomic Operator Control — the star knob profile allows operators to apply firm, even hand-tightening torque without tools, supporting quick panel or guard adjustments during routine servicing
- Long Service Life — correct OEM material selection resists cracking and thread wear under repeated adjustment cycles, preventing the stripped or stuck fasteners that a worn or incorrect knob causes
A star knob is a hand-tightened fastener used to secure access panels, adjustment covers, or serviceable components that require regular removal and reinstallation in the field. Its multi-lobe profile gives operators a confident grip without the need for hand tools, making routine maintenance faster and more practical on the jobsite. When a star knob cracks, strips, or becomes difficult to turn, panel retention is compromised — replacing it promptly with the correct OEM part restores secure closure and keeps service intervals on schedule.
