摘要： The disclosure is of a spreadable keeper for use in the cooperative slots in a machine tool spindle and its associated shank or tang. In use, the slots are partly aligned crosswise of the spindle axis of rotation and the keeper is inserted in the slots and screw-expanded to force the tang or shank more tightly into the tapered bore of the spindle. The keeper comprises a base on which are mounted cooperative camming members operable by a screw to expand lengthwise of the spindle for exporting the tightening force.
