A nut for anchor with a breakable fixing member is located at the end of the anchor bolt with screw periodic profile. At the butt end of the nut is made one or more fixing members, the size of which allows to restrict the movement of the nut on the anchor bolt with transferring of torque prior to curing of polymer filler in the hole, and then, when the resistance to movement of the anchor bolt is increased, the fixing members are destroyed, the nut is screwed onto the anchor bolt and forms tension therein. |
