SUBSTANCE: screw with captive parts is made in the form of a body with a threaded part on one end, with a head on the other end and with a plain part on the body between the threaded part and the head of the screw; it includes a packing and spring washer and a sleeve, and the plain part of the screw has a diameter equal to an arithmetic mean value of average and inner diameters of the thread. The sleeve is provided on one of its edges with an annular flange, the diameter of which is larger than that of a hole made in the part or an assembly unit, which is intended for installation of the screw. Outer diameter of the sleeve without any annular flange corresponds to inner diameters of packing and spring washers. Inner diameter of the sleeve is made so that free passage of the threaded part of the screw is provided through it. A slot is made on the sleeve in a longitudinal direction along the symmetry axis. On the sleeve symmetrically to the slot on the side opposite to the annular flange there are two mouldings of a spherical shape, which face with their projecting parts inside the sleeve so that distance between them is equal to the average diameter of the screw thread. Length of the sleeve to the annular flange is equal to total thickness of the part through which the screw passes, thickness of the packing washer and half thickness of the spring washer. Length of the threaded part of the screw is equal to distance from the annular flange of the sleeve to the mouldings of spherical shape.

EFFECT: simpler installation method of screws with captive parts.

SUBSTANCE: antitheft locking device includes a threaded part, a retaining part intended for installation on an object that is to be fixed, and a drive part intended for introduction into a wheel well, which allows transmitting the tightening or weakening torque to the threaded part by means of a wrench, etc. Connection of the wrench, etc. to the drive part is performed by means of matching grooves on the drive part and the wrench, etc. The drive part includes a cylindrical pin passing along the axis, and an insert in the form of a sleeve having the above grooves on the outer side. The insert is installed along the axis with the force on the cylindrical pin to take up the first position of use with possibility of taking up the second position of use, in which it is inserted deeper on the cylindrical pin; and with that, the insert is connected at rotation to the cylindrical pin by means of friction means. The cylindrical pin and the insert are made so that in the first position the friction means can arrange the transfer of the tightening or weakening moment, and in the second position the friction means cannot arrange the transfer of the tightening or weakening moment.

EFFECT: absence of possibility of unauthorised breaking of this device.
