No-Wrench Screw Anchor is also called Earth Helical Screw Anchor, it is a type of earth anchor, that functions by guying wires or cables within utility poles. It includes an anchor rod of forged-eye, angle-cut tip and a welded helix. Both the Triple eye and the Thimble eye Eye anchors have a rod with an enormous opening to support a turning bar that ensures the anchor is screwed on the ground. The No wrench screw is installed by turning it into the ground by a machine or hand.The extension rod ensures installation to a depth reaching the firm soil.
The anchor can be power-installed due to its eye that engages in the adapter of the hole-boring machine. The wrench anchor serves best in loose to medium-dense soils. After installation, the exposed anchor should have a final height of 8-12 inches extending the grade height. When the No-Wrench anchor is hand installed, it reduces the holding capacity by about 10-20%. Failure to adhere to the 5° installation alignment with the guying mass will significantly minimize the strength. The capacity ratings are only applicable to anchors that are properly installed.
