FIELD: engineering.
SUBSTANCE: invention relates to a torque limiting apparatus which is comprised of a nut and a locking member, wherein the locking member in the rear zone of the locking member has a top part with a driving profile for coupling the top part with a setting tool not allowing for rotation, the locking member in the front zone of the locking member has a receiving part with a receiving well open in front where the nut is set not allowing for rotation, and the locking member has means for applying torque from the top part to the receiving part, connecting the top part and the receiving part, wherein said means are destroyed at limit torque with interrupted connection between the top part and the receiving part. The locking member has no less than one fixating grab located on the receiving part and fixating the nut from the front part of the nut in the receiving well. Also a mounting system is described which includes an expanding anchor and said torque limiting apparatus, as well as a method of manufacture of said apparatus.
EFFECT: invention is characterized by high accuracy of fracture and reliability.
