Quality made in the USA, for anchoring down outdoor items that have small mounting holes. Are you searching for how to hold down a project to the ground that may only have a limited hole diameter which the flights or spirals of GroundGrabba's will not screw through? If you answered yes, we have created a threaded/hexless range that will help as follows. Threaded Range GR13UMT - 1.5 Feet in length GR13ULT - 2 Feet in length We have specifically designed these for uses such as outdoor sculptures, furniture, structures and various other items whereby up till now you may need to create a concrete slab and install permanent concrete anchoring which as you know is a time consuming and often expensive exercise. Our threaded ground anchors are a real game changer, done and dusted in mere minutes. How They Work Our engineered ground anchor flights (spirals) wind their way into the ground and create a tree root like hold. Then you simply bolt-down your base plate or item. Our hexless are made so after being driven into the ground, there will be a portion of threaded shaft protruding to screw on a supplied nut (x2) and washer. The Threaded GroundGrabba product line is meant for permanent infrastructure and placement. How To Deploy Hold Down Capacity Please look at our test below. Our GroundGrabba ground anchors will anchor down up to 7X that of a similar sized hammer in spike stake! Download PDF IMPORTANT***Please note that these figures are a guide only. The results are absolute peak readings and you should allow a decent safety margin. Ground types vary. Through the depth of one ground anchor the ground can be of different densities and affect outcomes. These all rely on correct deployment in dry conditions.
