Abstract
A quick lock nut (1) for positive friction locking securement of a disc-like tool (2) to an external thread (3) on a working spindle (4) driven about an axis of rotation (A), having an associated inner threaded part (5) and a manually displaceable tensioning means (6, 6′, 6″) for axial clamping and release of the inner threaded part (5) relative to the tool (2), wherein at least one flat spring (7) extending essentially parallel to the axis of rotation (A) is associated with the inner threaded part (5) on the tool side, by means of which the inner threaded part (5) can be axially resiliently tensioned with the tool (2).
