Overview

Big-Screw EZ Tie-Down is an innovative tie down system combining a lightweight 18 cast aluminum ground screw, and a custom aviation designed attachment strap. The 18-inch long cast aluminum screw provides stronger ground holding in all soil types. The screw penetrates deeply into compacted soils resulting in superior holding strength. This exclusive design provides two to three times the holding strength of spike type angled-in tie-downs. Large 1 Wide screw provides 80 Square inches of Ground Contact Area, 40 times more than a spike. The screw can be positioned either directly below or set out from aircraft attachments. Quick easy installation and removal using a 1 ratchet, 1 socket, or a portable impact wrench (not included).

The aviation designed EZ Tie-Down Straps ensure a quick and secure connection between the ground and aircraft. The 9-foot tie-down straps feature industrial strength weather-proof Polyester webbing, single lever locking strap tensioner, heavy-duty vinyl coated aircraft attachment double S-hooks, and cast steel Chrome Plated Tie-Down Clip. The detachable straps can be used on airport ramps without the ground screw offering additional versatility.

BIG SCREW TIE DOWN SYSTEM

December 31, 2022

The flashing left from the casting process was excessive and ugly and made it hard to turn the screw into the ground. It took me about an hour with a rasp to make all three look as nice as the ones in the pictures. Including the wrench, these weigh the same as the Big Steel Spikes I was using before. The improvement here over the steel spikes is the quiet screwing process. I didnt like the noise of driving the steel spikes into the ground with my axe.

We bought these in 2018 for our first trip to Oshkosh in a Cessna 206. Loved them. Worked great in multiple types of soil. Not easy in hard packed, gravelly, or dry ground, yet they did work (and Im not convinced that many other types would work at all, or very well). We have now used for multiple cross country tips and Oskkosh again. Highly recommend. Durable, easy to use, and strong!

Great tie down system. I have used dog tie style screws in the past. The Big Screw system is such a huge improvement. Easy to install amazing holding power. Great straps too.

Tried once and was very satisfied. Used a good wrench, so the installation was easy Fortunately the weather was good, but I was not worried anymore

Wow. Very heavy-duty. Ive never seen how serious, high-quality, and heavy-duty a simple tie-down could be until now. Its like you could use this to secure a Challenger regional jet in the grass at Oshkosh during a cyclone with this thing!

Looks great on the add. I though the screws were made out of steel. Its cast aluminum. If it were milled out of aluminum rod fine. But its not. Weak.
