ABSTRACT A fastener is disclosed suitable for securing a grinding wheel to the spindle of an angle grinder, the fastener being capable of tightening and loosening by hand. The fastener comprises a first disc-shaped component having a first pressure transmitting surface adapted to bear against the grinding wheel, and a second disc-shaped component having a threaded hub non-rotatably fixed thereto. The first and second components are assembled on the hub so as to be rotatable with respect to each other, and the second component is adapted to apply an axially directed compressive force to press the first component against the grinding wheel when a torque is applied to the second component. A solid dry lubricant washer is provided between facing surfaces of said first and second components in an annular recess immediately adjacent the hub, for reducing friction when one of the components is rotated relative to the other. The lubricant washer can ensure that a significantly increased proportion of the torque applied to the second component is converted to compressive force transmitted through the first component to the grinding wheel. A gripping device in the form of a flap is pivotally connected to the second component, and is capable of pivoting to an upright position in which the flap can be manually grasped to apply a torque to the fastener.
