CMI Bolt hangers were originally designed to be used in the ropes course market to be fastened to a tree or pole with a 5/8" lag screw.  The larger than normal size helps to facilitate tree overgrowth and allow extra time to keep using the hanger.  They are not to be used for climbing or slacklining.
