ABSTRACT:
In a first embodiment, a hexagonal threaded nut includes a pair of horizontal slots about a peripheral portion extending through the nut into a central threaded bore. The slots form jaws which are tightened by pairs of vertical screws about a threaded stud engaged within the central bore. The sides of the slots are forced together to firmly grip the stud. Stress relieving bores at the ends of the slots aid in applying a high torque to the stud and facilitate removal. A standard wrench can be used to rotate the nut and unscrew the stud. Another embodiment utilizes a pair of like threaded nuts positioned on a threaded stud with a fixed spacing therebetween. Screws passing through holes in the two nuts are tightened to compress the spacing and affix the nut to the stud to permit removal. One method for removing studs includes threading a pair of like nuts onto a stud to provide a fixed spacing therebetween, the nuts having a plurality of threaded holes, threading a plurality of screws through respective holes in said nuts, and tightening the screws to compress the spacing and affix the nut to the stud to permit removal of the stud.
