What is the purpose of a nut runner machine?

Automated nutrunning machines are industrial manufacturing systems that install threaded nuts over stud fasteners with minimal human effort. Nutrunner machines can position, screw down and torque nuts during the production of manufactured assemblies. A wide array of manufactured products depends on nutrunner machines, spanning medical device, automotive, electronic and many more applications. Human operators only need to load and unload the machine, and the automatic precision fastening system does the rest.
