Abstract:
1. An installation method for a component in an opening with an internal thread of a mating component, wherein a pitch per rotation of the internal thread is known, wherein said component includes at least one of a screw or an installation spindle with a threaded element in the shape of a wire thread insert, said threaded element comprising a plurality of adjacent helical windings, at least the radial interior of which is adapted in shape to a thread, in which at least one narrowed helical winding is composed of at least two helical winding sections, which enclose one or a plurality of adjacent secants, which constrict the narrowed helical winding radially inward, said method having the following steps: a) screwing-in said at least one of the screw with the threaded element or the installation spindle with the threaded element into the internal thread of the opening of the mating component; b) capturing a screw-in torque and an angle of rotation of the threaded element during said screwing-in step; and c) determining a position of the threaded element in the opening from the pitch of the internal thread and from a first covered angle of rotation after a first increase of the screw-in torque from a base screw-in torque to a first screw-in torque that signals an entry of the narrowed helical winding of the threaded element in the opening.
