Kennametal Accessories Retention Knobs WARNING Retention knobs are available in various styles and are not always interchangeable because all are machine and spindle specific. The proper retention knob must be used at all times with the appropriate adapter, according to machine specifications as provided by the machine's original manufacturer. Failure to use the correct retention knob, or to adequately install and tighten the correct retention knob, may result in an adapter loosening. Using a combination of metric and non-metric components can result in an inadequate coupling of the adapter to the spindle during machining, causing the component to fail. While Kennametal has endeavored to obtain accurate and up-to-date information regarding retention knob selection based on individual machine tool builder specifications, we cannot guarantee that the information and specifications contained in this catalog are complete and that they have not been modified or superseded by the manufacturer. You, the machine tool operator, are ultimately responsible for proper selection and use of retention knobs. The purchase of retention knobs from Kennametal is subject to Kennametal’s Standard Terms and Conditions of Sale. Machining center manufacturers use numerous types and styles of retention knobs.
