Quality made in the USA, for anchoring down outdoor items that have limited sized mounting holes. Are you searching for how to hold a project down to the ground and so far the only solution you have found is to lay concrete and then anchor into the concrete? ...Or, perhaps you are still searching for an easy cost effective way? Introducing our threaded range of GroundGrabba ground anchors. Our threaded earth anchors are perfect if you only have a limited hole diameter which the flights or spirals of GroundGrabba's will not screw through and you don't want to go through the drama of concrete pouring etc. Threaded Range You get to choose from our general use GR13 range and our heavier load commercial capacity GR14 range. GR13UMT - 450mm in length GR13ULT - 600mm 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. The Threaded GroundGrabba product line is meant for permanent infrastructure and placement. 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 commercial threaded hex-less are made so that after being driven into the ground, there will be a portion of threaded shaft protruding to screw on a supplied nut (x2) and washer. How To Deploy Hold Down Capacity Please look at our tests below. Our GroundGrabba ground anchors will anchor down up to 7X that of a similar sized hammer in spike stake! See the complete test chart here 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. Please also note that you will experience even greater ground holding as time goes by and the earth resettles undisturbed.

GroundGrabba is the heavy duty screw in ground anchor stake for sand or normal to firm substrates. To drive these into the ground you may likely need a very high torque impact wrench, perhaps as one of these or even with a higher torque ability: Makita 40v TW001GZ-40v Brushless 3/4" Impact Wrench Milwaukee M18 FUEL 2867-20 For all grounds please do drill pilot holes. You'll want to use a masonry drill at least the same length as the GroundGrabba you choose. Please Note: These are not toys. You will need a powerful drill if attempting to use these in hard ground. Disclaimer ⚠ Caution: ❌ Do not use in grounds where there are underground services such as but not limited to: electricity, gas, phone, data, water. ❌ Do not use GroundGrabba products for any other purpose other than ground anchoring. ❌ Not for timber, concrete, rock, bitumen, hot mix, tiles or Hard Large rocky grounds. Misuse or abuse of GroundGrabba products can lead to injury or worse to the user or bystanders. Not to be used with mains powered drills. When using Battery drills please refer to the drill manufacturers warnings and safety instructions prior to use with GroundGrabba products. Only use GroundGrabba products for their intended purpose of ground anchoring things such as tents and shade canopies. Always hold your drill firmly with both hands and use the inside of your legs as a drill guide with the drill handle in between your legs to help prevent torque twisting wrist or other injury. Always start your drill on the lowest torque setting. Use a good quality high torque drill or impact wrench. For hard or extremely hard grounds we recommend pre drilling a minimum of a 16mm pilot hole to help with insertion. Some grounds will be impenetrable. Use the correct GroundGrabba for the job. Do not rely on ground holding ability information herein. You must carry out your own ground holding as ground types and densities vary widely and therefore ground holding ability attained.
