FIELD: mechanical engineering.
SUBSTANCE: indicating device comprises rod, which is set in the opening of the fastening bolt. The rod is made of top member and bottom member. At least one of the members is made of a material with low elongation coefficient. The members of the rod tightly abut against each other over length Δl for permitting detachment when the bolt elongation reach a specified value during tightening. The top member of the rod cooperates with the compressed screw spring.
EFFECT: enhanced reliability.
