The Bomag 06421250 Star Knob is a genuine OEM component designed for Bomag BP 10/35, BP 12/40, BP 12/50 A, BP 20/50, BP 20/50 D, BP 25/50, and BP 25/50 D vibratory plates. Sourced directly from Bomag, this star knob delivers an exact match to the original hardware, ensuring proper fit and function right out of the box. If your existing knob is cracked, stripped, or missing, replacing it with the correct OEM part keeps operator controls where they need to be — firmly in hand and working as intended.
Key Features
- Genuine OEM Construction — molded and dimensioned to Bomag's original specification, so the grip profile and thread engagement match the factory-installed component exactly
- Direct Bolt-On Replacement — threads directly onto the existing stud or shaft with no modifications, using the same mounting interface as the original star knob
- Broad Vibratory Plate Coverage — confirmed fitment across the BP 10/35, BP 12/40, BP 12/50 A, BP 20/50, BP 20/50 D, BP 25/50, and BP 25/50 D forward vibratory plates
- Secure Operator Control — the multi-lobe star profile distributes hand pressure evenly, allowing confident tightening or adjustment without slipping or rounding off
- Verified Part Number — ordering by Bomag part number 06421250 ensures you receive the correct knob for your specific BP-series plate, eliminating guesswork on dimensional fit
A star knob is a hand-tightened fastener used to secure adjustable components — such as handles, guards, or depth settings — without the need for tools. Its radiating lobes give the operator enough leverage to tighten the connection firmly by hand, making quick field adjustments practical on the job. When a star knob cracks, strips, or breaks off, the component it secures can shift or loosen during operation, affecting both control and safety; replacing it promptly restores the intended clamping force and keeps adjustments locked in place.
