The A-S Series™ Stud Threaded Insert offers a unique design advantage in that once installed, a threaded stud is left protruding from the workpiece. Component parts can be located on the stud until final assembly is accomplished with a mating nut. The A-S Stud Insert is an ideal alternative to clinch or weld studs. The A-S Insert is designed to be used with Grade 5 or Metric Class 8.8/9.8 non thread locking type nuts.
