A description is given of a disc nut (1) for fixing system components of core drilling devices, wall and wire sawing systems and the like on threaded bolts, clamping spindles or the like that protrude from a receiving bore, which nut has a base body (2), which is formed in the manner of a cup with a bottom (6) provided with a bore (7), and a connection part (3) captively mounted on the base body (2). The connection part (3) has a through-bore (4), the inside wall (5) of which is profiled in the manner of a thread. From a head portion (9) of the connection part (3) there extends a shank (10), which passes through the bore (7) in the bottom (6) of the base body (2). The connection part (3) is arranged movably in relation to the base body (2), wherein an underside (12) of the head portion (9) that is formed in the manner of a spherical surface and a spherical surface on the base body (2) interact with one another. The spherical surface is formed by a ball socket (14) of an insert part (13), which is provided with a bore for the shank (10) of the connection part (3), is movably arranged in a recess (8) in the bottom (6) of the base body (2) and is prestressed with respect to the head portion (9) of the connection part (3). |
