The anchor is screwed into the ground, both the thimble eye and triple eye anchors have a rod with a wide opening to withhold the turning bar. The best thing about this anchor is that it can be power-installed because of its eye that takes part in the adapter of the hole-boring machine. When installed, the no wrench screw anchor reduces the holding capability 10-20%, while this failure is to stick with 5 degrees of installation alignment with the guying mass will reduce the strength. Also, these ratings are only valid for anchors that are installed correctly.
