Customer Questions and Answers for Gas Range Venturi Tube by Bosch

Slav, You'll need to be very careful if you're going to use an "easy out" or drill bit, you'll probably damage the orifice holder 00415498 and or the gas supply tube 00487244. 10 mm is a bit small,but it is a "metric" dimension. You'll want to have some anti seize compound handy when you put the burners back together, that will help to keep the venturi from seizing to the orifice holder in the future. The threads on the venturi and orifice holder are "standard" threads(clockwise to tighten, counter clockwize to loosen).
