The metal box is NOT grounded but I am trying to think of an example of how anything bad would happen. We know they are durable, climate-friendly and more cost-effective, and you don’t have to prepare the ground, dig large holes, cast your own supports and wait an age for them to cure… You screw them in, attach the structure, and you’re done!

Grassy or Unpaved Areas: They are ideal for installations in grassy fields, gardens, or other unpaved surfaces. The machinery used does not damage the surrounding landscapes and with no excavation there is no soil removal. In practice it will almost always be OK, because the light fixture is connected to the metal box with metal screws. I was told that a unpainted 10-32 machine screw can be used to connect the ground to a 4" square or similar J-box.These days a light fixture will have a separate green or bare grounding wire that can be connected directly to the bare copper wire in the electrical box. Via the screws" is only a valid grounding path if (by cause of tightening the screw) two metal surfaces are clamped together flush, hard and without contamination (rust, paint, those little plastic squares that capture the screws etc. The reason this is in place, is due to the product either being double insulated, or using a low voltage power supply. Our screws come in lengths from 800mm to 2050mm, to be able to create strong and stable foundations in most soil types and for a wide variety of projects.

Earth screws are an eco-friendly alternative to concrete, as they hold less embodied carbon, are faster to install, cause less surrounding damage, with no excavation, and they are removable, reusable and recyclable.While our range of screws offer these sustainability benefits, the best choice for your foundations depends on the specific requirements of the project, including load-bearing needs, soil conditions, and long-term objectives. If you remove a TEK screw, and then put it back in the same hole, can you get the same torque the second time? Reusability and Removability: Ground screw anchors can be removed and reused, offering a sustainable option for temporary structures or when changes are needed.

Our standard attachments allow you to build any structure on top of our foundation screws, but if you need a customised solution, we can manufacture it for you. Our range of screws presents a compelling and practical substitute for concrete foundations, offering numerous strong advantages, especially in sustainable construction.The 1000mm Self Install Ground Screw is a longer and stronger version of the 750mm Self Install Ground Screw. Let's say the hot wire got slightly nicked or abraded when the electrician ran the wiring (it happens).
