1 Retention Knob SOCKETS CAUTION: Retention knobs are manufactured to the specifications of the machine tool builder and any deviation from this could cause serious problems. Retention knobs are not normally interchangeable and failure to use the correct configuration can cause the toolholder to slip from the spindle which can result in serious damage. Retention knob fractures may occur from several factors, some of which are: improper knob configuration, mis-aligned machines, metal fatigue due to use, dropped tools, over torquing etc. Unless parts are ordered to a specific drawing or catalog number, we suggest you furnish a drawing of the part, make model number and serial number of the equipment requiring the knob. Read carefully when selecting a Socket.
