METHOD OF FABRICATION OF BOLT CONNECTION Russian patent published in 2009 - IPC F16B31/00 F16B39/22 C09K3/10 

FIELD: machine building.

SUBSTANCE: invention refers to general machine building, particularly to connection of parts and structure elements of railroad ways operating under vibration. The method of fabrication of bolt connection mainly under vibration conditions consists in applying material in form of anaerobic sealant, for example grade "Unifix P1", on a threaded part of bolt connection. Anaerobic sealant is applied on threaded surface so, as to fill recesses of thread. An applied layer of anaerobic sealant is levelled by run of a nut. Upon this operation the nut is screwed with torque equal to 150-200 Hm and conditioned within 20-30 min for solidifying of anaerobic sealant. An activator, for example, K101M, is additionally applied on threaded surface, when bolt connection operates under negative temperatures of ambient air.

EFFECT: upgraded corrosion resistance of connection and prevention of unscrewing of bolt connection.
