The black 00635147 knob kit for Bosch, Thermador and Gaggenau gas cooktops (including the Thermador SGS304) is discontinued by the manufacturer, and owners reported months on backorder before that. Replace the full set: design once, set the bore to your stem, and order four or more for 10% off.

Shaft fit: Dimensions not published. Measure the valve stem with a knob pulled off. Knobulator lets you set the exact bore shape and clearance. Compare the preset with your original before ordering; a part number alone does not confirm that the bore matches.

Customize — pick your shaft → Design from scratch

Pull the broken knob off and check the shaft first — then set the exact bore. Replacing the full set? 4+ knobs get 10% off automatically.

Is this an original manufacturer part?

No. Knobulator makes custom designs, not original manufacturer parts or exact replicas. Brand names and part numbers identify the replacement you are researching; they do not guarantee compatibility.
