Beschreibung
Zusammenfassung:	FIELD: mechanical engineering. SUBSTANCE: bolt has auxiliary members with whose help self-locking of threaded joint may be ensured, for example, riffles with negative cutting of chips, coat which is dry film lubricant between friction surfaces and surfaces to be hardened, blind slot (slots) at end of threaded axle for auxiliary bending of drill in micrometric range and distribution of contact working surface of turns of thread to avoid transfer of twisting and bending loads on entire length of bolt. Bolts has other advantages in self-locking due to delivery of thermal energy to area of active threaded surface at moment of self-locking. EFFECT: enhanced reliability and extended range of technological capabilities. 4 cl, 6 dwgF
