HF-64 Hanger For Welded Stud
The HF-64 Hanger is useful when one side of the beam is not accessible, such as bridge widening projects. A 3/4 inch diameter threaded stud may be welded to the top flange (similar to other shear studs), and the HF-64 hanger with a special 90º end fits over the threaded stud and is secured with a 3/4 inch UNC nut. Actual safe working load is mainly dependent on the weld of the stud to the flange. Care must be taken to assure a proper weld in the field.
The HF-64 Hanger may also be used on a concrete beam by drilling a hole in the top flange of the beam and epoxy grouting.
