SCREW CONNECTION, PARTICULARLY FOR COLLARS AND COLLAR Russian patent published in 2016 - IPC F16L33/04 F16B2/08 

FIELD: installation.

SUBSTANCE: invention relates to a screw joint, in particular for a collar, and is aimed at achieving the simplest way of geometrically reproducible installation of the final state of the screw connection. It is a screw connection, in particular indicated for a tensioning clamp, with a screw having a screw head and an external thread having a thread profile and a threaded shaft, and a counter-threaded member, that the male thread adapted internal thread with at least one of the thread flanks limited thread notch and into which the screw can be screwed. External threads at a predetermined distance from the screw head have a geometrically defined deformed portion which when screwing the screw into the mating threaded element is facing at least one side face of the thread profile and which is formed by plastic deformation by molding at least one profile of the thread in the radial direction.

EFFECT: deformed portion extends substantially parallel to the perpendicular to the thread axis.
